Could be a number of issues:

1. Low battery power in the transmitter.

2. Receiver has a loose connection and needs to be re-soldered.

3. Other transmitters in your house interfering with the signal.


I have this type of helicopter or similar model.

Before flight, of course we check all batteries are fully charged. The helicopter may stopped as soon as there is vibration on the ground or while mid flight.

What I found out recently, there is this small cylindrical component (capacitor or crystal) of the circuit board with a loose/dry solder. This could be the cause of the glitch which you encountered. My heli is now grounded because this component has broken wires due to regular physical interference to correct the glitch. Not sure whether this component has spares or not.

Make sure that you use the helicopter indoors. I have one, and it won't work outdoors for too long. Try recharging the batteries too. You also need to stay within a certain range or else it will be come unresponsive and crash.

Don't know if this will work on a model but in Viet Nam when the engine conked out you did an "autorotation" to set her down easy. Helicopters are designed specifically to allow pilots to have a reasonable chance of landing them safely in the case where the engine stops working during flight, often with no damage at all. They accomplish this via autorotation of the main rotor blades.

Here's a training video on how to do it in several different choppers:
