Common RC Heli Control Configuration

Co-Axial Heli
Co-Axial helicopters use a counter-rotating twin rotor design. Two sets of blades spinning in opposite directions eliminate the need for a tail rotor and provide excellent stability making these helicopters an ideal introduction to the hobby.

Collective Pitch (CP) Heli
Collective Pitch Helicopters alter altitude by changing the blade angle using pitch servo combined with increased RPM from the motor (pitch/throttle curves decide the exact input of each variable and can be altered depending on ability).

Fixed Pitch (FP) Heli
Fixed Pitch RC Helicopters only have 4 channels and they increase in altitude by increasing power to the motor. They have curved blades to create more lift and lack the collective pitch (blade angle) method of lift. They have a very simple servo configuration making them easier to repair than a CP Heli.
