UDI RC U840 2.4G 6-Channel Nano Quadcopter w/ Bonus Battery (extra play time) - Yellow

This is a fun nano quad! You'll get entertained for hours flying them around your house. It takes some practice and once you get the hang of it, it makes the experience way better.If you are just starting out, a few tips to remember.Fly with guards, especially at first since you will crash or hit this against something. As you get better, you can take it off and your flight time will also increase. Charging time is at least 25-30 min for a 5-6 minute flight time.The good thing is that this comes with 2 batteries so you can swap out when one dies and continue the fun/practice. Bad thing is that these batteries and also chip are reversed polarity so your other chargers (Proto-x nano, Hubsan nano, Cheersons) and batteries will not work. I've read people modding theirs but for the price of these, I decided to just leave as-is.

I'm a quadcopter enthusiast. Having multiple quads, full size and nano. I must say you get nothing! Good day sir!! I purchased 2 and both were inoperable right out of the very neat well made package. They look great and are made well but seem to have motor issues. Both of the left rear motors failed to run on both quads. One motor per quad in the same location in the clockwise motors. I refuse to work on a quad new out of the box. But I must say they have a good return policy thankfully. Find a different nano. These aren't the droids you're looking for (0B1)

I bought 2 of these, and like every other nano quad I've flown they sometimes become disoriented during flight and you have to land them and let them get their wits about them. still, the u840 does fly pretty well. NOTE: DO NOT FLY NEAR HIGH POWER LINES! I was flying one of them up high, at least 100 feet, and a high power line came between the quad and the transmitter. the quad stopped responding to input and took off to the east apparently following the high power line. It kept going east at that high altitude til I could no longer see it. I guess there is a frequency emitted by the high power lines that can possess your quad. Bye-bye little birdie.

Totally Amazed! At first, I thought this was just another nano quad, with a pretty cool color scheme. But this thing totally blew me away! The transmitter is even smaller then typical nanos, although it has a great feel. It has great controls and super easy to fly inside. It has three rates, with a yaw rate that changes with each rate. It has a nice smooth and stable six axis gyro and its insanely fast in high rates! Not to mention, UDI gives you an awesome display case that stores the transmitter, spare props and usb charging cable. Overall this is one of the best nano quads I've ever flown. I absolutely recommend this to beginners or experienced pilots. Its a ton of fun, and the interchangeable battery for this size quad is an absolute game changer!! GET ONE! You won't regret it!

Junk. Gyro's nonfunctional from the box. Hard left all the time. This was out of the box and no amount of resetting did the job. A real disappointment.The controller is tiny, fits in my palm. If your hands are large like mine controlling this is very difficult.Another set of troubles are the constant removing of the battery and no on/off switch. Wires will break, should you have enough flight time and bend them a few times. Had to be very careful.Battery didn't want to fit, but modified it slight by pinching the wire end from the sides just a bit.Overall a cheap unreliable nano quad, A waste of money and time.

Looks very cool and when flying it is fairly decent. But the thing never was able to be trimmed to satisfaction no matter what I tried, and I have owned several other nanocopters as well. Not bad for the money but doesn't hold a candle to the Syma X12 which is in the same price range.

I am not sure what to say: simply put, we didn't read instructions, we turned it on and it just flew away! To be honest, while I was disappointed that it was gone, I was really impressed with how fast, high, and far it went off into (quite possibly) the stratosphere. It was an exhilarating 10 seconds for my whole family as it faded into the distance and over the tree line. We scoured the woods for its remains, which I'm certain that jackpot tickets have better probabilities then finding this dinky thing. I would say it was worth the few dollars spent, and have dinged it on 1 star since it is not biodegradable. I came home after the loss and bought another, fingers crossed.

this is my second one. first one i was so amazed on how well it flew and how fast.. then i bounced in the wall and two of the motors stopped working. i need up buying a second one, and soon after within two weeks one of the motors isn't working well causing it to fly crazy and crash. needless to say i won't be buying a third.

Great item, keeps my husband amused for quite a while, seeing as it so little

Not as good as the Hubsan q4. Quad is a bit unresponsive at times and calibration not very accurate.

Awesome great fun and amazing for such a little drone

I give it 5 stars for delivery and only 3 for quadcopter itself. This thing does drift all over the place but I'm new to this so I'm sure there's a learning curve. Still really fun for the price.

Great little drone but after about 4 use, the power on/off is not working properly anymore....cannot fully enjoy it anymore.

It is not the easiest micro quad to fly.

Good toy for the money but sometimes it drifts to one side I recommend this for more experienced pilots
