Helicopter is described as controlled radio, or it is not an infrared radio frequency remote control. In short, the transmission is more than random, if the helicopter is not exactly in front of the remote control, it does not. For information, I am in my third model, purchased from the seller and competitors. Always the same problems. All models are identical, the prices range from 15 euros including postage to 45 euro for some. A tip, go your way.
