A MUST HAVE QUAD COPTER FOR ALL BEGINNERS TO PRO'S!!!!
March 7, 2016
Excellent little quad copter I would highly recommend this quad copter if your a beginner like me! And even if your a pro you would still have fun with this thing it really zooooms outside but watch the wind! If you get it up to high and theres a pretty good lil wind blowin it can fly away real easy if your not careful I've chased it a few times lol! All in all though it's a great flyer and easy to fly. You have to go over the instructions for the controls and how and what the controller does and it's fairly easy to understand, I had no problem getting it to take off!! And after a short time maybe an hour and remember this is my first quad EVER I could easily maintain a hover and that's the key I found once you can keep it still with little effort the flying is all good!!! Recommend this quad!!! Full review here--[...][...] Holy Stone Mini RC Quadcopter Drone Helicopter with Camera,2 Batteries & 12 propellers,Perfect Drone Trainer
November 21, 2015
A great trainer for beginners. Easier to fly than the smaller one I first bought from another place. Resolution is 640x480, not the best, but for the price a great deal. I flew it so high it got out of range and I could not control it. It lost a prop and came crashing down and partially broke one of the motor supports. See image of disassembled unit. Surprisingly after I attached the prop it could still fly. Being technically competent, I emailed the company and asked if I could get a replacement body, since the motors and electronics still worked, I figured I could switch the body. They sent me a returned unit that was marked as defective, the body was good and I was able to swap the parts and fly again. This swapping of bodies was a challenging and not really a task for those unskilled at this sort of thing. My point in telling you this is to show what a great company Holy Stone is; the damage was my fault, but they were willing to help me by granting my unusual request. Hey said they would help me, and they did.Thanks Eliza
Fun to fly and TOUGH as nails!
August 7, 2015
This was my first quadcopter and it hit the ground/floor A LOT at first. I found it excellent to learn to fly with because it hovers well and it survived a lot of wrecks. Time after time I would pick it up, dust it off, and it flies again. It is terrible to fly outdoors with any breeze whatsoever, but for a beginner/training quad, this was a great choice. The camera/video was a joke, but this thing is only $35 bucks, so you either get a decent quadcopter or a decent camera, but not both for $35 bucks. I would recommend this to a friend as a first quad. The customer service was... persistent to say the least. Until you unsubscribe, expect to receive 3 or more emails per week asking how your toy is working. I even got a random phone call from someone wondering how my product is working. A little too much attention, but I understand that the importer is trying to establish a name.
This little copter is Dangerous - to your budget!
July 17, 2015
I got this copter as an entry level trainer for myself. In 30 min I was up, running, and buzzing around the house. Within an hour I was using the camera feature! It was quick to learn, fast to master, and gave me the confidence to purchase a Hubson. Even still, I come back and fly this copter. My wife uses it, as do both kids. I'm going to get a second so the kids don't have to fight over the one!Now for the cons,As noted in other reviews, the tab to open the door does come of quite easily. When my wife was learning, she twisted it off on her second battery. But, like others, I simply removed the door. This turned out to be a plus as I was then able to stick a 500 mAh batter in there and fly for even longer!The Prop Guards break. By the time I was competent with the copter, the first prop guard had snapped. It could still be attached to the copter, but anything short of a perfect landing would cause the guard to quiver, get caught in the prop, and be subsequently ripped off. So, I spent a lot of time re-attaching them. Even still, they did their job, and absorbed the impacts that inevitably come with learning to fly.By the time my son was done training, a second prop guard was snapped. It was an annoyance for my wife when she started to train, and I had to remove them entirely for my daughter - who had to train outside as the house is too small to learn if there are no prop guards.Finally, the budget. I was recording video with the copter (which has sound!) during the first flights, and while I was carrying it outside, I made the comment, which was recorded, how this little copter was going to be very dangerous to my budget. I was right. As soon as I saw the aerial footage of my property, from when I flew it around outside, I was hooked. I purchased more batteries, prop guards (so my daughter can learn), and even a Hubson! But I still like flying this copter.I've taken it hiking - for aerial footage in the woods - and even got a travel case for it.All said. for the price point this is an awesome purchase. Just be forewarned: It'll bite you with the Areal RC bug, I know, because it bit me!
Great little drone for the price!
May 27, 2015
I have really been enjoying this little drone for flying around the house. It's small and light so I don't have to worry about breaking anything, and it's really fast! I found it a bit more difficult to control than my u818a, but it's likely because of the size and weight of this drone in comparison. The model that I purchased included two batteries and 12 rotor blades total. That makes this a no brainer at the sub-$40 price point. Pick one up for yourself, they are great!Pros:-Price is nice!-Fast!-Small and light!-Two batteries-extra parts-sd card reader included!-customer service (see light bar comment in cons)Cons:-Gets away fast. This is not a child's toy. It will take time to learn to control it.-I had one light that was not working all the time, but the manufacturer sent me a new light bar for free! ++ :)-The battery is a bit difficult to stuff in the compartment, but it's nice not worrying about it falling out sometimes like it does on my U818a.Overall:This is a must buy for anyone who is on the fence about getting a drone, or anyone who just wants to have one for fun. I also appreciated the service I received from Holy Stone when I needed help.
March 29, 2015
Totally awesome toy. For the price the video and pictures can not be beat and its just a lot of fun.Also let's talk about the durability for a minute. We lost connection over a large tree that is well over 2 stories high in the neighbors yard across the street. It tumbled all the way through the tree and down a hill - all the while recording and then landed upside down. Its just fine and the video from that adventure was great. The audio itself was priceless when we finally found it. I believe someone was coo'ing about being "so happy the little buddy survived the fall". Yes that would be the husband who went down the hill to retrieve it.Its good fun. I've added a few screens from video we shot. This is our first time with one of these and we are impressed. And we are buying a second one in a different color for me!!!
Love it. Just wish the snow was gone so ...
February 20, 2015
Love it. Just wish the snow was gone so we could get it outside. My grand daughter who is 13 picked it up fast. I am still practicing with it. It is a great quadcopter to start with. The camera takes decent pictures and movies. Once I get this one down pat I will be getting a better one. But for the money it is worth it. Oh yeah, it is a good idea to order some extra batteries as they only last around 6 minutes. I ordered 5 extra batteries that came today.i will get these charged and keep them on hand. I recommend this unit for beginners. My only complaint is the batteries only last around 6 minutes but I knew that before I bought it.
Drone better than anticipated. Patience is a virture.
January 14, 2015
The GOOD. Ordered evening of 1/7/2015. Estimated delivery 13th-17th. Arrived afternoon of 9th.Packaged very well, read instructions (couple of times because English version a bit cryptic, but decipherable). Charged the flight battery supplied ... always takes about an hour to green light on charger. (I've since ordered two additional flight batteries.) Plugged in 4 AAA's (not supplied) to controller and did initial flight testing on our billiard table. The user docs states the rear left black rotor should turn clockwise, and rear right black rotor anticlockwise. Physical rotation is just the opposite to balance the front white rotors (left clockwise, right anticlockwise). So ignored the doc on this issue.Came with four spare rotors, one for each location, charger, and USB cable for camera.Time of use is ten plus minutes depending if you leave the five led lights on (top right button on controller flips them on/off). The undercarriage blue lights in front and red in back are always on. Number of photos or how much video you take also makes a small difference. Ten minutes of full concentration on my part is enough. I'm over 60 by the way. (A 12 year old would already be an expert.)In order to fly well, the unit must be above it's backwash, I found that to be at least three feet off ground level. The controller screen has a bit of information on it, which is not well described in the manual, but is easy to figure out. Lights, photo, camera, indicators.The REALLY GOOD. Little thing is well designed and constructed. I've crashed it a dozen times or so, hard landings on floors, roadways, parking lots, and trees. Even have a great video of flying it into a tree 20 feet up, cutting the rotor power, and watching it fall into some waste high bushes. No damage except to my ego. I've even tried a couple of times to chop off my fingers, the rotors just stop, and the design compensates to insure no damage is done to the rotors or blades or fingers. Trying hard not to do anymore self testing on this issue.I've been using mode 1 for beginners. A mode 1/2 I would find useful. Mode 2 for experts I'm not even planning to try. The controls are really sensitive, and you need to anticipate the power, flight, etc. If you are keeping the unit in the same location off the ground it will tend to continue to rise until you begin to panic and reduce power. If you fly the unit, it will need more rotor power to not loose altitude.Sensitivity to wind is real. So I've given up trying to even fly if there is anything more than a light breeze. After all, the unit weighs less than the birds I've scared out of their trees a couple of times.The pictures and video are surprisingly good. Pictures are 1280x960 or 550KB files. The pictures and video require a steady flight, something I'm working hard to yet achieve. The video of my flight into the tree is actually a bit too clear. I've included a picture I was finally able to get of the front of our house that is actually in focus. For the price, this is a great purchase.
Perfect quadcopter at a great price!
January 13, 2015
My son got this for Christmas. He loves it! We downloaded the pictures and videos onto my computer and they're very clear. I highly recommend! Here's a photo my son took of our house with it!
The best Quadcopter for the money out there.
December 6, 2014
I have owned the quadcopter for about 2 months now and it is still flying without any damage after countless crashes.The outerframe is flexible and resilient which is nice for learning. It has led lights with a flashlight on the front you can turn off and on via the remote control.It has a sport mode(mode 2) for more power. I think its better for outdoor flying. there is a button on the controller to change the mode near the lid screen.It also has a trick button. You hit the flip bumper button and turn the stick and it flips in that direction(Does not work out well indoors) .It does flies pretty stable though for pictures and videos. It takes video and pictures easily via buttons on the controller. Don't expect HD quality video/pics, but it's better than what I expected for $60.Wind can be an issue flying outside, but it's small enough to fly inside while you get a basic understanding of the controls. An explicit outdoor version of this for up to $120 would be great!Battery life is approx 10-15min depending on flying style and if you are shooting video. FYI, spare batteries are cheap and I would recommend buying at least 1. I think 3-4 batteries is a good amount if you are rotating with someone.
Great Starter QuadCopter
July 1, 2014
My first foray into multi-rotor flight. I picked this up as a starter set based on advice from a local users group that learning to fly is best done before investing in a copter that does all the work for you by relying on gps and altitude locks. You will need to actively fly the UDI U818A. It's stable in flight, but easily pushed around by the lightest breeze. It doesn't hold a specific location or altitude on its own. It worked right out of the box as soon as I had charged the flight battery. Be warned that there is plenty of power to send this flying quickly out of your control range, which will then cause it to loose synch and flutter lightly back to the ground (or tree top). The only damage mine has incurred is the occasional displacement of a prop shaft that needs to be pressed back into place to fully mesh the offset gearing.The on-remote trim switches can be used to dynamically adjust the stability of the quadcopter. You can zero out any slight side slipping or rotation by tweaking the three trim switches this way or that. Once that's done, the copter will park itself quietly over a single location until the next change of wind or joystick input disturbs it.The onboard video and picture snaps are not high definition, but they are static free and very stable when loitering at altitude. You won't know what you've captured in the camera until you get it back to your computer to transfer the files from the camera via the included USB cable. For those who might prefer an FPV setup, there is an upgraded model of this quadcopter on the market that swaps out the onboard storing video camera with a broadcasting camera that your wifi equipped smart phone can receive video from.
Remarkable Quad For The $$$
May 6, 2014
This Quad is really very nice for the money. I paid $65 for the UDI 818A with camera included. I removed the safety canopy and replaced it with one I made from a plastic cup. This allowed the quad to be more agile due to less surface area contacting with the wind. I suggest the Turnigy 600mah batteries. These take about 45min to charge and give about 9min of flight time. Also, due to their discharge rate, they provide allot more response from a lower throttle position. The auto-stabilization is pretty extreme which make this great for someone learning to fly as well as a stable platform for taking pictures. The camera itself is nothing to write home about but it works as advertised. One thing to note is that this quad is virtually indistructable! Crash after crash, it continues to perform reliably. Out of the 9 quads I currently own, which range in price from $40 to $175, the UDI818A has proven itself to be the best overall value for my money.
Four Star Reviews:
A good kind of cheap fun!
November 10, 2015
This little bugger has provided me much entertainment, and is a wonderful trainer for new drone enthusiasts! Other reviewers pointed out the latter, which is one of the primary reasons I selected this drone. I've found this toy to be very durable! It has survived many impacts and 8-foot drops onto solid concrete floors. The blades tend to fly off rather than break, due to being friction-fit to the axles. This also means that blades can be very easily fit back on in moments, so a mere blade strike generally does not hinder your fun! The included blade guards likely contribute to the drone's durability, bUT i have nto flown withe them off, so I cant say for sure. But it's solid protection and you should definitely use it.I wish battery life was greater, but it's on par with other drones of its size. Flying easy in the "slow" mode will get several minutes of flight time, but improving to "fast" mode and putting it through its paces will reduce flight time to around 4 or 5 minutes. Extra batteries are recommended; the 2 included ones won't keep you satisfied. I just ordered another pair with a multi-charger that will charge all 4 at once.The camera is the only feature I'm going to be a stickler about. Think back to early cell phone cameras, circa 2003. My guess is that to save costs, the drone manufacturer went to the dump, dug up a bunch of cell phones from this era, and recycled their cameras. Don't get this drone for the camera. Seriously. It's worthless. If you want a decent camera, shell out some additional cash, and don't look back.Camera aside, this drone is a great toy, and a great way to learn to fly drones. To these ends, I highly recommend this product! I can't say I'm an expert pilot yet, but after just a few short weeks (with fewer-than-daily flights), I absolutely feel comfortable with basic skills and would have no fear flying a much larger, more expensive model! Training is ongoing, however, because I have my sights set on racing.
Great for a beginner - small but tough
October 23, 2015
Works mostly as described, but if using outside, is *very* affected by any slight breeze (took away 1 star for this). Would be a good unit for a beginner, as it seems to take a fall without breaking into bits (as other brands have). Have not been able to get the camera to work - did not take away rating because of this though, as we're unable to figure if it is User-end related (us not knowing how to work it) or Mfr issue as yet. Kept it at 4 stars mostly for the toughness of it - during a flying 'learning curve', has had numerous crashes with no major breaks. Item is small, too, about 7" side-to-side and about 2" tall, so can be flown indoors as well.
Great value for money. Little large for indoors and has some jumpy tendencies
September 12, 2015
Flies well and fairly stable. A little big for my apartment but it can probably fly well outside even when there is a slight breeze. It is controllable in my place but I can't really do any maneuvering. I detracted one star since it does feel a bit jumpy/fidgety.I'm an experienced RC pilot and bought 4 of these inexpensive mini quads but did not realize this was about double the size of the other 3.(That isn't necessarily a con, I probably should have paid more attention to the size / did a little more research. It does seem that either there isn't a standard way to measure these mini quads (between motor axles or blade tips?) or sometimes the package size is given here on Amazon.)I dislike the auto-flip feature on these things. I wish I could get it to bind to my computer hobby transmitter.This was the only one out those I've tried at around the same price which has a camera (records video or can take stills but no FPV). I don't have an interest in that aspect of quads so I have not tried it. Maybe I will later or maybe I'll remove the camera since it is basically dead weight.I will try it outside if we get a decent day here in the Northeast.
Good value for a sturdy UAV / copter
August 12, 2015
I have to say, i'm a bit suprised by the sturdiness of this thing. My kids have been crashing this for the past 2-3 days, sometimes from heights of 4+ meters. Propellers fall off, even broke a few, but it's still in one piece!Ok, so on to the review:Pros:Good build qualitySurprised by the video qualityTiny, lightCons:A bit difficult to fly - takes a lot of practiceCant hover in one place on it's ownI would not recommend this for small kids, but if your kid is +10 years, then why notUPDATE:Well after a few months playing, I crashed it bad, and one of the motors died.A new replacement kit is $17, with the toy being less than $50, so considering for a replacement.
Quadcopter good, Holy Stone excellent.
August 11, 2015
I do like the quadcopter, but a few issues with it:1) it's terrible at doing flips. I've done 1 flip successfully indoors with dozens of tries.2) the outdoor range isn't that great. It could use a better antenna.3) the camera isn't all that great of quality, and it's 4:3 ratio, not HD.The first unit had some issues: the battery warning came on usually after the battery was dead. The first unit had terrible audio recording, and had issues keeping synched up with the radio. Also, with the first unit, flight time with the camera OFF was terrible - maybe 2 or 3 minutes, and it would suddenly lose power though had only flown for a minute or two.The second unit seems to not have camera audio issues, the warning lights flash a few seconds before the battery dies (could be better), the flight time seems better, but still it doesn't do flips well...I have taken it outside and it does decently well - flying it at my son's school yesterday for quite a distance.Pros: Holy Stone customer service is radically excellent. They even called my house (first ever) the day after I received the unit. When I told them of the issues, they immediately sent 2 replacement batteries and a replacement unit. The replacement quadcopter showed up within 2 days, and the batteries within about 5 days or so - from China.They did call, however, at 8:30 at night, which was not a good time.Cons: Needs better camera, better warning with low battery, better flips. (I don't get other reviews that show excellent, easy flips. Not my units - either one)I'm about intermediate with over half a dozen small helicopters and quadcopters... my favorite is the Cheerson CX10 - which flies amazingly well for it's tiny size - with warning lights that tell you your battery is done with plenty of advanced warning - a unit I've had for nearly a year with zero problems.Thanks, Holy Stone, for being so proactive in your customer service. Even though I have some minor issues with the second unit, I'd likely purchase from you again because of your excellent customer service.

It IS a very good drone to learn the flight controls associated with most ...
December 12, 2016
I got this drone as a gift for my 8yr old. I ended up playing with it more than he did. You will NOT take spectacular video with this and you will NOT be able to go very far without risking a fly away...which means a healthy run when the battery quits.Having said that, this drone really isn't intended for those things. It IS a very good drone to learn the flight controls associated with most higher end commercially available drones. It is somewhat difficult to fly in that it is very sensitive to inputs and -of course- has no GPS locate/hover capabilities...which means you will be walking to retrieve it after a crash, which happens a fair bit (especially at first). I had a hard time getting it to hover in place for more than a few seconds because it is so light weight. The video camera is hard mounted, so any changes in attitude are picked up on video, leading to a lot of rocking and rolling on screen.However, considering the price point, all of this should be expected. The drone is entertaining to fly, and got me used to controls prior to my purchase of a popular higher end brand. The battery life is actually pretty good considering the size of the batteries, and they are inexpensive so get at least one spare (preferably two). I was able to eek out the stated battery time on mine pretty reliably as long as I didn't use video or marker lights. Finally, this is a ROBUST little drone. I crashed it....a LOT. It survived to fly again every time. Based upon that alone I would recommend this little guy if you just want to tinker and learn.I think I have been spoiled by my current drone, because this just isn't five star material, but considering the price point, and time I bought this (over a year ago and newer products etc.) I rated it at 4.
Great Quad to Learn On!
December 17, 2015
This is the quadcopter I learned on and I still enjoy flying it! Its very stable and lightweight, which also makes its affected heavily by the wind (don't try to fly over 7-8 mph wind gusts unless you're an expert). The controls are easier than another "drone" I have and after learning on it for awhile its an amazing intro into quadcopter/ "drone" flight. . I also LOVE flying this drone at night due to all the LED lights on the underside and front of it; it would be a very difficult toy to lose in the dark. Overall, I'm very happy I purchased this and continue to have fun with it! I'm attempting to upload a video here that I took with the quad when I flew it on a nice calm day in a picked cornfield. Most of my videos/ flight last around 1 minute before crashing back to earth, but it gives a good example of what this toy is capable of:
Great started quad copter with some issues
November 30, 2015
This is a great starter quad copter for a number of reasons.1. Price, obviously. :)2. It's mod friendly, in that the plastic guard is easily removable and all components have plastic connectors to the main board so components and can removed/replaced without any cutting/soldering of wires. Battery is very standard and you can (and should) upgrade it.3. This thing is a tank. Even after removing the plastic guard and flying this into a variety of things it is still working great.4. It has a button that does an auto 360 flip, which is really cool.A few cons however.1. Battery is 580mah and will only get you ~5 minutes of flight. Upgrading to a 1200+ battery is highly recommended, I get about 15 minutes of flight with mine now.2. Some of my friends who have bought this same unit had issues where trim had to be adjusted. I did not encounter this, but it suggests QA might not be great here.3. The controller is a joke. If you open it up, you'll notice the throttle trim button doesn't have any connectors on the board and is only cosmetic. The antenna that sticks out of this remote is not the actual antenna and just a filler. My antenna was actually pointing towards me and not the sky!4. On that note, the throttle is super sensitive. The slightest touch will cause it to jump 5-10% so it's almost impossible to find a sweet spot to hover. It makes it all the more frustrating that the throttle adjusting buttons are missing on the board!
His favorite Birthday gift
March 23, 2015
Bought this for my son's 9th birthday, and it was the first experience with a quadcopter/drone for both of us. I'd definitely recommend this as a good starter unit. We were both able to fly it with a decent amount of control the first time out. We learned quickly, however, that this model is susceptible to the slightest breeze, so keep that in mind when you take it out. Also, consider buying a few extra batteries to extend your flight time, 7-8 minutes goes by quick.Having an onboard camera is what I looked forward to most. It does work - taking pics or video is easily triggered right from the controller. But don't expect high res images. This camera isn't even up to par with low res camera phones from 10 years ago. But considering the price, I can't complain too much. They're at least good enough to get a birds-eye view of your neighborhood. And it did come with a generic 2gb micro SD card installed.My only real complaint with ours is one of the rotors had a malfunction right out of the box. 3 of the 4 spin immediately when power is applied, but the 4th needs a slight push to get it to spin up. Again for the money, it wasn't worth returning it. But since it won't take off with only 3 of 4 rotors spinning, if I ever accidentally land it on a roof, I won't be able to fly it back off, I'll need to get the ladder out.Overall, for the money, this is a decent, well performing drone for first timers.
Worked awesome! Great Fun!
December 31, 2014
Took my boys out to the park and we made our initial flight w/ our Quadcopter this afternoon. Worked great! Just wish the battery lasted a little longer. You only get about 7 minutes total, so I recommend some additional batteries. The video/photo capabilities are fantastic.
Great little Quad at a great price!
November 22, 2013
This is a great flying little quad, although it has been fairly windy since this has been delivered I have still enjoyed it, it does fair in light wind but it is a very light little machine and a gust of wind will pick it up and carry it away fairly quickly, It's a tough little bird though, I hung it up in a tree yesterday and instead of freaking out I looked and saw how it was hooked to the tree then I flew it right off the branch fairly easily, then instead of getting hung up even further up the tree I let it fall the rest of the way down, it smacked just about every branch on the way down and really don't even have a scratch on it.The camera is a fairly decent little camera although I upgraded the MicroSD card fairly quickly, the 1gig card fills up pretty quick. I use a USB cable to copy the video files to my computer instead of taking the SD out every time I'm sure taking the card in and out so much will wear it out fairly quick.The remote is great, it feels comfortable in hand and has digital trim settings and a digital readout showing throttle setting, remote battery life, trim settings, camera settings, etc, it also has the 360 inversion button you can tap to make the quad do flips, be sure to have some altitude before doing this a be ready to hit the throttle again to keep the quad from hitting the ground, you can also use the top left button for this, press it and when it starts beeping you can tap you rudder controls up, down, left, or right ta make it flip in the direction you like, this is a little more fun than just the 360 inversion.Other than that there is not much more I can say about this Quad other than I love it, I do plan on building my own quad in the future and this is giving me some great training on the physics of a quad and how to fly one.Let me add that some proper care an manteinence of your LiPO batteries will make them last long, There are many videos on Youtube on proper care of your batteries but here are some tips.* Your batteries will come from the factory charged, but not fully, Charge them fully before flying.* Do not run your battery down all the way, leave about 20% power in the battery, you can purchase voltage alarms that will buzz at a specified voltage.* after flying wait about 15 minutes for battery to cool down before re-charging.* when putting batteries up for storage do not fully charge them, charge them about 80%.
Three Star Reviews:
Fun but frustrating.
March 14, 2016
I have trouble flying this for a couple of reasons. I've missplaced the instruction manual and haven't figured out how to get the trim working, so it's always drifting off to the right and forward and turning, unless I correct it with the controls. It's hard to keep it hovering, much less make it go anywhere. My other problem is keeping track of which end is the front of the aircraft. I'm used to RC planes and it's pretty easy to identify the nose vs the tail without thinking. When you have to thing, let's see the yellow is .... oh heck I forget, now the green lights are ... By that time, the quad has turned 120 degrees to the right and flow off. It's fun but frustrating. I'm sure it'll be lots better if I can ever get it trimmed.
Ehhh, could be better. You get what you pay for.
August 26, 2015
Ordered this for my godson, he loves it. This is a really cute little toy for a little boy but it is much smaller then we expected. It can easily fit in the palm of your hand. Another downside, is one of the led lights went out about two hours after we got it. I didn't even notice, but my godson pointed it out to me. The copter still flies though so he doesn't mind - however, as I was the one that paid for it, I would have liked for all of the lights to work. Nice that it comes with an extra battery but you get less then 10 minutes of fly time before the battery dies. Would have rather purchased a more expensive copter that would hold charge longer.
Comparison of several drones
May 25, 2015
Comparison of several dronesLarger dronesHoly stone M62R - Too big for inside, too small for outside. Difficult to fly. Camera not very good.Holy Stone® RC Quadcopter with 2MP Camera M68R(Plus) - Too big for inside, great size for outside. Easy to fly. Has headless mode but it would occasionally go out of headless mode when batteries got low and go out of control so I quit using headless mode. I got the white one and painted the back half neon orange making it easy to see. Keep it oriented in the right direction and there is no need for headless mode. Has lights that make orientation easy to see at night. I've had it to about 200 feet high. Definitely recommend this one.Mini dronesSyma x12 - Small and easy to fly, good for indoors and out. Recommend this one. I took mine to about 100 feet up and it drifted away in the wind and got lost. I will probably buy another.Cheerson CX-10 - Smaller than the syma and harder to fly. It bounces around a lot so difficult indoors. Too small for outside. Was supposed to come with spare blades but it didn't. Broke a blade and can't fly it until I buy more.
Great Quadcopter Handicapped by Poor Battery Connector Design.
May 23, 2015
This is my first Quadcopter so this is a Newbie review. I would have given 5 stars except for issues with removing and installing the battery. The assembly was very straight forward and I had no issues. As I started to try to learn how to fly in my small apartment, I thought I'll never learn to control it but after three or four batteries of practice I can somewhat maneuver it - even in the small confines of my apartment so in an open space I imagine it would be very easy to control.The copter is amazingly durable as I did crash it into the ceiling and numerous pieces of furniture without any damage!The one issue is with the battery connector. It is extremely hard to unplug the battery from the connector. And it is also extremely difficult to fit the battery and the connector into the copter. I've started to fly it without closing the battery compartment - which works. Impatient kids or guys with brawny hands are inevitably going to damage the battery connector - leading to a high return rate. A needle nose pliers (or maybe a set of two) would come in handy to avoid ripping out the battery wires.
I should of got a SYMA X5 (the battery compartment placement sucks and is less than accommodating)
February 3, 2015
Fairly new into the world of Quadcopters,but Iam guessing most people are!!!This is my "3rd" quad (I have 2 other Syma small small quads)The "yaw"(twirling effect) on this model is excellent compared to my little Symas. It spins in place. The controls will be a bit to get used to (watch the reviewers video to learn how to control camera modes)The overall controls are OK its kind of sensitive (at least mine is even after re-calibrating)Video in low light is like any digital camera in low light (it sucks) but in the sun for this price its pretty good!!!The copter it self is LIGHT weight the shell is a light plastic (if this thing lands on concrete hard BYE BYE)also the wind can do a number on this one (make sure its not very windy outside when using it)One of my propeller (cheap) guards broke and I had to buy a new set of 4 (shipped from China $4.50)*****IM NOT A FAN (understatement) OF THE BATTERY COMPARTMENT IN THE FRONT (the placement AND CONNECTION is horrible)*****Trying to fit the battery back in with the wires and shut the compartment takes EFFORT!!!!!! Taking a spare battery out with you might not be a good idea(time consuming to switch). If you dont close the front compartment air flow can get in the quadcopter(compromising its stability) ANNNNND the compartment door being open BLOCKS THE CAMERA!Its a TIGHT TIGHT FIT with the battery and accompanying wires (BE CAREFUL)Sometimes it takes minutes (like 5 or more) to "push" the wires in and finding a place where they fit snug without compromising the front latch or damaging the wiring.I have also had problems with detaching the battery from the quad. The wire connector sticking and me fighting with it to get it loose/separated.In end its an OK quad for the price. I would look into a quad that has the camera that hangs down from the belly as opposed to one like this where the battery compartment could be a problem because the camera is directly under it.VERDICT: Its as big as a hand (maybe a little larger) the build feels cheap but flys good, video is good in sun light, battery compartment and connectors SUCK and almost ruin this one. Propeller guards will more than likely need to be replaced.IF I HAD TO DO IT AGAIN ID BUY THE SYMA X5 (old or newer edition) over this quad they are around the same price.To be honest I have more fun (in doors) with my tina SYMA X12 nano quadcopters than this one and this one is more powerful and has a camera just all the effort that goes into it at times makes it less than deserving of my time and maybe yours!
This is a pretty cool little quad-copter
January 28, 2015
This is a pretty cool little quad-copter. This thing is a blast to fly and is sure to put a smile on your face the first time it lifts off! The only three things that I see prone to failure in this particular model is the battery connection which is a remote connection (one male/ one female connector attached to wires, it seems it would be a little easier if per say the casing of the battery had contacts on the outside) and the poor quality of the blade protectors.Finally my last complaint ( I know, I know) is that the charger cable could be a bit more resilient. The controls are a little touchy at first but can be refined in time. The video and pictures are excellent quality for such an inexpensive copter and the spare props are a major plus. This thing is sure to give you hours of fun!

March 15, 2017
It has many flaws, but a good thing is that this thing can really hold up to a 11 year old smashing it to pretty much everything. The problem is that it loses connection out of the blue and it keeps flying in the same direction as the last command received; this meaning if you're moving it forward and loses connection, it will just keep moving forward until battery runs out or you (somehow) get to catch it.
Great beginner and first-timer's drone
May 26, 2016
This is an excellent drone for anyone wanting to get their feet wet. The controller is similar to the more expensive drones so this will help with becoming comfortable flying drones. I gave the drone three stars for the sole fact that it is very reasonably priced for this type of drone; however, it has it's major flaws.The first main flaw of this drone is it's extremely light weight and flimsy plastic-like design. On a barely windy day, be prepared for the smallest gusts of winds to carry your drone away. You are actually probably better trying to fly this drone in a large open indoors area (only where permitted of course). I have crashed this drone several times and although the design is a flimsy plastic, it has absorbed the impacts and yet to break on me; however, I can see how easy it will be for the propellers or drone itself to crack or break off if crashed (I guess I have just been lucky so far, only crashing onto cushioned grass from low flying heights).The next major flaw is the drones flying time. I know all drones have a short flight time related to battery, but this drone allows for 5-7 minutes of flight time max.The last major problem with this drone is the complexity of the operating the drone, controller, and drone's camera plus the lack of a descriptive manual to explain everything you need to know. I have still yet to figure out how the camera works, or if the camera even does work, because I cannot seem to find enough information regarding the operation of it, let alone the ability to keep it in flight outside long enough without the wind sweeping it away or the battery dying.Overall, it is a low priced, great drone to buy as a practice drone if you are looking into wanting one of the more expensive, high-end drones. If you are wanting this drone for the ability to take pictures, record videos, or spend hours of time outside flying around, then this IS NOT the drone for you. I look at this drone as purely a learning and practice only drone to help familiarize yourself with drones and their controllers to better operate the higher-end drones when the time comes so that you don't have to fear crashing the more expensive drones like you more than likely will with this one several times.
Don't try to fly it in a breeze.
November 25, 2015
It's very lightweight. So much so that any slight breeze has a profound (and lasting) impact on your ability to control it. The battery lasting 9 minutes is no joke, which is too bad. As light as this thing is, I would think they could include a slightly larger (heavier) battery and be able to sell a much better product. Buy extra batteries. The low-res camera produces video that you would expect from a low-res camera. Don't think the video is usable for anything other than fun.Comes with a USB cable to download video and/or pics to your computer, and, surprisingly, a 2GB Micro SD card already in it; 4 extra propellers, wall charger and tiny screwdriver. Instructions are typically convoluted from being translated from some other language (Chinese?), but they're understandable enough. Seeing the video on your computer is very straightforward and easy - just put the Micro SD card into a SD card adapter, or plug the drone into your computer with the included USB cable.Note: I paid under $50 for it, which was around half price on a Black Friday week special deal. If I had paid anywhere near $100 for it, I would send it back. It's really just a toy that I intend to use for drone practice.
Interesting but basically a toy that gets worse over time.
November 17, 2015
This thing lasts maybe 3-4 minutes and can barely get about 50 feet in the air the first time before losing the ability to climb and it only gets worse over time. The first half dozen times this thing would go 100 feet in the air and fly for 5 minutes or so but the flight time and power continues to drop as time goes on.

December 8, 2014
Check the battery charger. Don't use the one that came with unit if it is rated at 6 vdc. Batteries are only 3.7 volts. The 6 volt charger will overcharge the battery and make it swell up due to overvoltage.
Great..IF! You don't get a defect.
May 12, 2014
*Update at bottom of review!*This a great learner quad. IF you get a perfectly working product, this is a 4.5 Star product.There are plenty of great technical reviews of this product so I will not get into that here.What I will review will be after-purchase experience.The very first time I charged and fired these up, I noticed that one of the the motors made a different sound than the other 3.Straight away it was very difficult to keep a steady hover. Had to do some trim adjustment and got it to respond well enough.Upon closer inspection of the weird sounding motor, I noticed that the rotation of the blade made a noticeable "clicking" at a certain point. None of the other motors are showing that either.I figured the motor wasn't going to last too much longer so I contacted the seller to see if I can get replacements.They were prompt and courteous but they didn't have it in stock so they suggested that I return it since it had only been a few days since purchase. I did consider it BUT...They do not have an exchange policy so only way to do this would be to return this and purchase a new one.Unfortunately for me, the current prices are quite a bit higher then when I purchased it so.... it turns out its cheaper for me to keep my defective unit and just purchase a replacement motor from china for $15. I rather eat the cost of a cheap new motor than pay more for.... nothing...Also you will only get about 4-5mins of flight time on the stock battery. BUY extra batteries at purchase. Flying for 5 mins and charging in 30 mins does NOT make for efficient use of your idle time. I bought a 5 pack battery that I am STILL waiting to get (shipping from china remember?). Maybe I will get it next month if i am lucky.Potential buyers should be aware of what you get in this product.IF you get defect free product, you will get a great sub $100 entry level quad-copter to fly indoor and out.Replacement parts and accessories are almost ALL shipping from China, so expect LONG shipping time.I will update this review after I finally receive my replacement motor and spare batteries.Update *5-19-14Got the 5-pack of 600mAh extended batteries. Ordered 4-28, received 5-15.The updated batteries are nice, and having 6 (5-pack plus original) of them gives me a theoretic flight time of ~30 mins BUT, there is a potential problem.After going though about 2 batteries, I noticed the motors of the quad are SUPER hot.I do not think these motors are designed to be running non-stop for hour long straight duration.No doubt they will last the full 30 mins of flight a few times as I have already tried... but I do not think they will continue to last in this fashion.I recommend no more than 10-15 mins of continuous flight times with rest periods for motor to cool down.Still waiting of the replacement motor...I think they shipped it via row boat...Either way I think I found another alternative that can solve 2 of my problems.Each replacement motor costs around $15 each. A quad copter has 4 of them so as long as I can get a full set for 60 that sounds right?Well, you can get a brand new U817A unit here on Amazon for $65 shipped on Prime.The only difference between the U817A and the U818A is the 18A has build-in camera, the 17A does not.So I can get a full set of replacement motors including the main body unit, body housing and the remote for $5 more?I am already invested into this quad because with the batteries, so sounds like a deal!Remember I said 2 problems? Well the second problem this solves was the original problem this update started with.Once I do get my replacement motor (shipped via row boat) I would have 2 fully functional quads to fly with.This would allow me to swap my 2 quads at 15 mins intervals so they can both have time to cool down the motors between flights.Plus will allow me to rotate 7 sets of batteries (5-pack plus 2 from original) for charging and flying continuously.This way I can maximize my valuable down time with more extended flight time without the risk of reducing product life-cycle.Some of you might ask: Why spend so much for a set of cheap quads when you can get a Parrot AR for a little more?Well my total cost so far: Original U818A $65, 5-pack batteries $27, 1 replacement motor $15, U817A $62.Total Cost $169. For 2 quads and 7 batteries with near continous flight time very little worry from crashes.(These UDI quads are very resilient to crashes but VERY prone to defects!)The next nearest "upgrade" would be the Parrot AR which is $299 at its base package.Better materials? Yes. Better build? Yes. Better value? Maybe not.You may get slightly better "experience" than a base U818A that is less than $100 certainly.But even with 2 sets of UDI quads, the Parrot still costs over $100 more.And for the job of quad trainer/beginner, a set of these will far out-last a Parrot, as they are far more forgiving on crashes.After I feel I have garnished enough skill from these quads I plan on upgrading to the DJI Phantom (in cart waiting for price drop:)) which I consider is an upgrade worthy of its price.Sadly my skill level is far below risking on a $500 quad, so for now these UDI quads will hopefully give me enough longevity and experience to take me to the next level.I have raised a star for OVER-ALL VALUE to 3 stars, but due to high amount of defects I have seen in other reviews,that was validated in my own case, plus the ridiculous shipping times for all related replacement parts or accessories,it would be hard to recommend any higher.Though I have decided to even go so far purchase additional units of this 3 star product, I do so under unique compromises that I doubt most would be willing to take.For me, I needed a trainer/intermediate quad that was very forgiving on crashes, with maximum total continuous flight time (I don't have a lot of free time) on the cheap.This fit the bill for me but definitely not for all.I will do another update once the motor or the new U817A arrives.The faulty motor is getting worse and the quad has a VERY hard time staying level even with very aggressive trim adjusted.I can still fly it, but it just isn't as easy to control as it used to be.
Two Star Reviews:
June 2, 2015
Right out of the box I saw that the designers for this copter were concerned with PRICE and not with QUALITY or Functionality. Ease of Use has never been something for them.The compartment for the battery stinks. The little door only closes if you have a pair of small tweezers to stuff the wires back into the hole. They could have made that a hard mount connector. The Camera should be hard wired with an on and off switch. We Americans are not that stupid, we know how to turn on a switch, but we do not like to push a button and then see flickering lights and then pray the camera is on and fly the darn thing at the same time. Dumb design! The issue with the 512 M memory card is that I feel they bought out the stock from a company that went broke 10 YEARS ago. 512? Who deals with anything that small anymore?!Does the Copter fly? Yes it does. Does it take Still Pictures? Yes it does. Does it take movies? I don't know. After 2 says of reading instructions and tinkering with it, NO VIDEO! Am I going to send it back? No, I don't give up. Will I buy another from this company? H*** No.
The UDI818A is my least favorite of the three
January 10, 2016
OK, I have an Air Hogs Millennium Falcon, a Syma X5C and this. The UDI818A is my least favorite of the three. The reason being, it's wild (in a bad way).1. It doesn't hover at a stationary point. It drifts to the left (yes, I've recalibrated repeatedly). So I have to trim right and back every time I fly.2. It doesn't really hover at a fixed altitude. It either climbs or drops like a rock.3. The range is poor. It loses connectivity to the radio transmitter at about 150 feet and blinks like "wtf where did you go hurr durr".4. The guard doesn't really protect it. I knocked on the motor brackets loose on a hard landing. It snapped back on, but still, sub-optimal guard design.So again, it's my least favorite drone. The Millennium Falcon can only really be flown indoors; even a little wind will send it into a neighbor's yard. And the X5C is so much easier and fun to fly. And considering it's half the price of the UDI818, it's really a much better value. I feel good about my X5C purchase and like I got screwed with the UDI818A. They're both hobbyist/entry level quadcopters but one is half the price of the other.
Be VERY careful before buying this product
January 7, 2016
My 11 year old son wanted this which could be used in our yard or in an open field. Nothing too taxing but just something fun to play with. When we got the FIRST one he played with it for a while and it broke. The issue was that not enough power was getting to one of the four propellers so it was not able to fly. We happened to be within the 30 day period to return it so we did just that and got a replacement. Guess what...about a month later with the new one the same exact thing happened to the drone. One of the propellers did not receive enough power and thus the propeller would not turn fast enough and the drone could not fly. Unfortunately this time we were just outside the 30 day period and we were not allowed to return it. There was no abuse or misuse of the product...just not a very good product as far as what it is supposed to do. Also, now that we cannot return it, there really is no way to get it fixed since the parts are small and specific. It is really too bad that the producer/seller of this will not stand behind their product.
I crashed this thing from 40 feet in the air onto concrete and it still operates and looks like new! -pre-programmed 360 degree
January 2, 2016
Temper your expectations based on videos you've seen where a drone flies effortlessly and precisely to the whims of the operator. This is not that drone.Pros:-Inexpensive-decent video camera-extremely durable. I crashed this thing from 40 feet in the air onto concrete and it still operates and looks like new!-pre-programmed 360 degree flip maneuver that looks cool-comes with extra propellersCons:-no live video feed-battery lasts only 5-7 minutes and takes an hour to charge-nearly impossible to fly with any precision. This drone requires constant correction by the the operator just to stay in one place. Even after endless fumbling with trim settings, there is always an imbalance in the flight. The controls are wildly sensitive. In order to achieve stable flight, the operator has to make impossibly tiny micro-millimeter adjustments on the stick. You always end up over compensating which inevitably results in a crash.It's a good thing this drone is made so durable because I guarantee you will be crashing it, A LOT. Don't even think about taking it outside if there's the slightest breeze. You will loose it straight into your neighbor's backyard before you even figure out what's happening. All in all, it's tough to enjoy this product because it's so frustrating to fly. Do yourself a favor, spend the extra money and get something that has some kind of electronic flight stability. What good is a drone if you can't fly it for more than 1 minute without loosing control?

December 26, 2015
Christmas present for my son. It started out great, he was very pleased to be up and flying comfortably after waiting for the battery to charge. Controls are fairly easy to adjusted to and he was quickly able to control the quad while in close proximity. First 3 flights were great and he was able to capture some fairly good video. (quality of the camera is pretty good for its size but all the videos were taken in bright daylight. I am sure this helps).The fourth flight is when the trouble came. He had the quad about 60 feet overhead trying to get a decent video of the area. Apparently this is close to the range of the controller. Instead of lowering at the point the quad lost contact it slowly drifted up and away without responding to the controller. We were on a slope and as the quad drifted away its elevation increased the distance even as my son chased it down. The verbal pleas while chasing the quad where not enough to get it to descend. The trees on the edge of the field now have a new resident.For the price I had hoped to avoid this type of behavior. I will continue to look for a unit that has quality communication with the controller.

December 11, 2015
The 818A HD+ is definitely better. I got this one for two reasons -- to practice on the older version before beating up the HD+ too badly, and because with the sale price it was about the same as buying replacement motors in the event they may be needed.ADDENDUM: Unfortunately, I have to amend this review. This one flies even worse than the HD+. (Which I also reviewed.) I had originally given 4 stars, but after working with this drone for several weeks, I've discovered that the controller is what I would call "too loose." It's almost impossible to get good control of the drone because even small taps on the controls make too large an adjustment. It flies all over the place with very little control. Control of the craft also changes according to the power left in the battery. A fresh battery really sends it flying out of control. The trim buttons don't work well, and the drone does not hover in place well because it constantly changes which direction it wants to go. My son bought a JJRC Super Scorpio, equivalent in size and features to this one, and in trying it out I found the controls to be more stiff and therefore much easier to fly the drone on even my first attempt. They're out of stock right now (Dec. 23, 2015), but I would recommend waiting until they're back in stock and buy one of those.
quick to die
April 7, 2014
Gave this as a present to my cousin who loved it. A little underpowered but at this weight class what do you expect. Wind does tend to have its way with it.Unfortunately what we figured out is that the electronics are slipshod on this device. Less than two weeks later and its going back for a return. The camera part of the unit completely stopped working, creating no video and the USB port was dead. a complete loss. We also noticed that the unit has no way to date stamp the video it takes, all video is labeled as filmed in 2008.This got me poking around a bit and I realized that this machine has a barely functional IO control for that camera. Only the tiniest bits are there, allowing video to write to the card, and use the USB, but no more than that. I suspect that this OS has no error handling or recovery so once it corrupt, its game over, and its gonna corrupt because its a quick and dirty slap together.So while it works, its great, a fun little toy, but that is all it is and is a little pricey for a unit that is only going to provide a weeks worth of fun.

awful waist of money! never flew straight right out of box,could not fly with any resemblance of control. crashed (on grass) and broken within an hour of first flight.

June 5, 2016
I received the drone and it did not contain the charger or camera. Without the camera and charging off my PC, it works well enough, but I paid for the one with the camera and charger so I'm giving the product only one star. More a reflection on the seller/packager than the drone, since I can't tell how well the camera would have worked. I bought this to learn how to shoot simple video with a drone, so I'll just end up keeping this to train with. I could return it to the seller/Amazon, but the costs involved and the loooong wait time to receive the drone in the first place make that less than desireable.Update. One of the controller trim adjusts died. 2 of the LED lights died. This is after maybe 20 minutes total flight time, with full charges, over 2 days. It lifts, spins on its own, and is not steerable anymore. No crashes or damage - it just won't fly under any control except throttle. I cannot control or fly it due to the spinning. The front LED is one of the dead ones so I can't tell which way it should be flying. Total waste of time and money. Threw it away. Bought one locally so I can get service if I need it.
Do not buy this product!
December 25, 2015
This is extremely fragile and should not be purchased for learning drone users. The battery must be disconnected by a tiny connector that is also fragile and is the only way to turn the drone off (stupid design, how about an on off switch?). The machine functioned fine through one battery (7 min) and 2 min into the next battery, then one of the motors stopped working and would not spin the blade. There is no troubleshooting guide in the "manual." Happy Christmas morning to my child this was purchased for.
Practically DOA and costly to repair
November 14, 2015
When getting ready to fly (purchased November 11th), the wire to one of the motors that powers the wing failed once the wing start propelling upward, a bad solder of wire made it easy to lose connection. Beware that the house of the motor in enclosed by plastic pieces so to get to the motor you'll have to buy the house wing housing unit which cost 10 dollars plus shipping from hong kong, with the flying beating from falling of this RC drone you really can't avoid the costly imperfections of this item. 1/5 this item is not worth it in terms of repair.
Good reviews would have to be fake.
June 16, 2015
Motors die after one day of use. All cheap, parts and design. Does not fly straight. All the good reviews are not correct. As this is a complete piece of junk. You can't contact the manufacturer as they don't have an English support line.
Exercise in frustration and sixty bucks down the drain
April 1, 2015
I was a complete newbie to RC flying and thought the U818 would be a good place to start considering the number of 5 star reviews and the low price but alas this was not the case. Like a lot of other cheap products produced in China it is a total crap shoot as to whether you get a good or bad one. First off I did not experience any of the out of box problems that others are reporting. The battery charged properly and all four rotors worked and turned in the proper direction. The transmitter synced without issue and the gyro appeared to calibrate per the instructions. At this point I was getting excited, just maybe I got one of the good ones. The excitement soon faded when I attempted to achieve a stable hover indoors.. The copter took off straight up to about 3 ft and then started to veer to the left until I hit a wall. At this point I thought okay this should be easily corrected by some simple trim adjustments but this proved to be futile as even though all three trim adjusters did make changes to the direction no matter how I tweaked them I could not get a stable hover for more than about 15 seconds before veering off in some random direction and hitting something. Not being the type of person that gives up easily I turned to the Internet for some guidance. There are numerous hits when you search, but the R/C forums seem to have the best info on things you can try to fix various issues including achieving a stable hover. I tried them all, from removing the outer blade guard shell to trying different gyro calibration techniques but all to no avail. Obviously since so many people are able to fly these things successfully there must be something wrong with mine but, at least for me, it's just not worth the time and expense to return it so at this point I am throwing in the towel. To sum up, if you are the gambling type, and won't cry over a $60 loss go ahead and buy one, maybe you will get lucky and join the ranks of the 5 star reviewers.Update to my review:For those that have given up trying to fly one these and haven't pitched it in the trash yet, try this. I glued the end of a 20 ft kite string to the center of the camera and tied the other end to a dumbbell laying on the ground, creating a tether to keep the copter from flying off. It worked pretty good. I slowly gave it about half throttle and it rose up until the slack went out of the string and actually seemed to hover fairly stable without any trimming. I didn't try it but am certain if I cut the string it would make an uncontrollable bee line to the nearest tree. Of course basically all I have now is a $60 dollar electric kite but at least I have been having some fun shooting some video albeit in a stationary view. One side note I was only able to make this work by removing the blade guard. With it on it immediately dove to one side and crashed when I applied throttle.

February 13, 2015
While the basic core structure (frame and board housing) is stronger than most in this class, I was very disappointed that this quad came with an issue out of the box. My UDI U818 came crashing the ground abruptly on it's first two flights despite a full charge. These crashes came without warning and I wasn't even close to the flight time limits described by other users. I was only about 3 minutes into the flight when it fell like a rock with rotors stopped. After charging a third time, I realized that the power supply wires soldered into the main board were lose and power from the battery was interrupted, causing the crashes. SECOND - I bought this at the same time as a Syma X5C-1 to compare, and what a difference! when it would fly, the UDI U818 would jerk from side to side on the horizontal axis (not good for aerial video), whereas the Syma was smooth. Also, the Syma flew as expected, did not have any repairs out of the box like the UDI, and is a clear winner in my opinion. Don't waste your money on the UDI.
