For $21, this electric helicopter is outstanding. The construction is perfect. The gyro makes it fly smooth and hover accurately. 3 channels means you can’t pitch the heli side to side, only forward and backward. Actually, this makes it easier to fly because it reduces the complexity of controls.
The size of components is amazingly small. I still can’t get over the size of the electric motors. You get about 6 minutes of flight time out of a 50 minute charge using the USB charging cable.
