It should be determined by the weight and load of the helicopter.

The characteristics of the pneumatic motor are that compared with the electric motor which plays the same role, the shell is light and the transportation is convenient; Because the working medium is air, there is no need to worry about fire. When the pneumatic motor is overloaded, it can stop automa......

Typically an outrunner motor is a Permanent Magnet Synchronous Motor (PMSM) torque motor. Therefore, the motor consists of a stator with coils and a rotor with permanent magnets. With conventional motors, the magnets are attached to a shaft that rotates on the inside of the stator coils. This is cal......

The servo motor can control the speed, and the position accuracy is very accurate.

Brushless Motor has low noise and smooth operation.

Brushless DC motors use semiconductor switching devices to achieve electronic commutation, that is, electronic switching devices are used to replace traditional contact commutators and brushes.
