Gyropter not lifting off after full charge

did you put the blades on the right way
you will notice that the leading edge of the blade will be slightly curved and this curve has to be at the top of the blade so that as it is spinning it creates lift and so lifts the chopper of the floor

i am really glad that this isnt a REAL helecopter. if you got it for christmas, you might want to return it- that is, after you verify that it is FULLY charged. this sounds like a half charged battery, that isnt spinning the bigger blades as fast as it should.

this could also be caused by any obstructions to the blades ability to rotate freely, something stuck to the blades- adding weight, bent blades, or internal belt/gear issues, regarding regulating the main blades, and the rear stabilizing blades timings.

if, before the charge, the dying battery caused the copter to crash, a blade could easily be bent, or have mud or something on it, weighing it down.

if the copter really is indestructable, i would go right back to a bad battery.

if the rechargeable battery got a memory after 4 days, i feel bad for you and your kids.

You have a bad flight control board. There may be a loose wire near 5be charge port making fontact wi5h the output circuit for the main rotors. Good luck

How do I charge my Nano QX 18 Gram Quad-Copter?It came with a USB cord but I can not get it to charge.Do I have to go to a specific web site?

did you charge it that might be the problem

Maybe it is out of power an needs a charge? Also, if there is alot of pet hair, dust, and human hair, it could have gotten some in the axels in the blades causing it to spin slower, and could short circut the whole battery if you keep using it with the dust in it. I suggest taking all of the blades and axels and stuff off the main body of the helicopter and take all of the excess dirt and dust off. I hope this helped :)

The light will keep flashing unless you are on the correct channel A B or C and you hit the "Light" button on the front of the unit.

As far as the high speed take offs I suggest identifying which A B or C setting is correct for your copter. In order to do this turn off the RC controller. Set the Selector switch to "A" move the left joystick "throttle" half way up and then turn on the power. Assuming that the copter is still ON it will either fire up or do nothing. If it does nothing try the same sequence with the selector switch set to "B" and try again. If nothing try "C".

Now, as far as the rapid accelleration, I read one online comment that indicated that there is some type of "programming" sequence that the unit learns by pushing the left joystick throttle all the way forward and then back to zero when you start to fly it. So after the first "blast off" set the copter back down or even hold it in you hand by grasping the the landing runners and move the throttle forward until the rotor spin up and it lifts off. In your hand it is easier to keep it from going up too quickly.

Good luck!

This issue is the "Drive Gear Unit" It is the small gear just above the motors which is attached to the very large gear. You will have seen several posts indicating that sometimes this gear shifts and does not engage the larger gear. In my case I looked and say that it was indeed trying to engage the larger gear, however the gear is stripped (the teeth are nearly gone). The sound that you are hearing is the sound of the gear slipping against the Bigger gear. I have a UJ365 which is a newer model. To my disappointment I cannot find a "Drive Gear Unit" anywhere on line. The copter will not function without it. This issue is that it takes the lift of both rotors to lift the copter into the air. There are two motors (one for each rotor) and each motor has one of these drive gear units. Each of these attach to the larger gears which turn the rotors. The rotors each turn in the opposite direction. This is what keeps the copter from continually turning in one direction. When one of the "main Gear Units" becomes damaged it seems to have three noticeable effects. (1) There is a noise that is the gear grinding against the bigger gear. (2) Because many of the teeth are stripped the drive gear engages the bigger bear only some of the time, this causes the rotor to turn slower and in-turn causes there not to be enough lift from the rotors to lift the copter. And finally (3), someone noted that copter wants to spin in one direction. Understanding the above, you can now understand that if one of the rotors is not reaching its full potential to turn, it is also not reaching its full potential to counter act the other fully functioning rotor. Thus the fully functioning rotor is forcing the copter to spin in its direction and the malfunctioning rotor is not spinning fast enough to stop the spin.

So this is the answer to your questions, hopefully on the older models there will be parts available for you to replace it. The copter cannot work until the part is replaced.

The problem may be due to broken blades or untrimmed. Change the blades with new one is the first option if the same is all right trim your copter through trimmer button on remote. sometime copter not fully charged and this problem occurs.

definetly a short circuit some were in the copter itself

There pretty good about returning those items they can be a lot of fun good luck james
