What is the biggest motor problem in electric helicopters?
Helicopters are “Rotary Wing Aircraft,” thus, if the wing is not rotating, they will not fly. Turning the rotor becomes a full time job because there is no rest time for the drive system like there is in an airplane. The rotor must be turning 100% of the time. Additionally, the only airflow to the motor is the constant load. Therefore, overheating becomes the biggest concern for helicopter models. MEGA Motors are designed with air flow in mind ultimately keeping the motor running cooler, longer and more efficiently. The MEGA ACn 22/30/3H has a motor shaft that goes all the way through the motor allowing an impeller to be mounted on the back side to blow air through the motor. Many helicopter enthusiasts have turned computer video card fans into impellers for motor cooling as a result of overheating.
