Controlling an RC helicopter is a bit more complicated than your average RC vehicle, however, because of the way a helicopter flies. To lift off the ground, a helicopter requires a complex interaction of blades and rotors. When you fly an RC helicopter, your radio transmitter sends information from multiple channels at certain frequencies to the receiver. The receiver, located on the helicopter itself, interprets these signals into up or down movements, right or left turns, forward and backward tilting and leaning right or left. Most radio control helicopters also contain a gyro, which automatically controls the tail rotor for you.
