Abstract
A control device for use in unmanned model aircraft for a constant speed propeller is disclosed. The device comprises a propulsion engine coupled to the propeller. The rotational speed of the propulsion engine is regulated through an automatic change of the angle of attack of the propeller and a manual or automatic adjustment of the throttle. It also comprises an electric servomotor device, a power transmission and a controller. The servomotor device is positively coupled to the propeller via the power transmission. The controller controls the servomotor device. The variable angle of attack of the propeller is adjusted by the power transmission from the servomotor device and the propulsion engine, manually by an operator or automatically by the controller.
