why are rc helicopters so noisy?
RC Helicopters are fun, but noisy..is it because the electric motors are noisy or is it the rotors moving through the air that makes so much noise?
It is the rotors making the noise.
As a helicopter crewman for 15 years we always had to listen to the fixed-wing pilots favorite joke about helicopters:
"They don’t FLY… they just beat the air into submission !!"
Seriously, the electric motor is almost silent. There will be a high-pitched whine from the gearing system. And the loudest noise will be the rotor-tips pounding the air. ALSO, there is a secondary noise from where the rotors cross over or near the tail rotor.
