Proposed method and device could be applied as controlling system facilitating the maneuverability and stabilization parameters of UAV, as well as various flight objects and small satellites. The aim of the invention is to reduce the occurrences of imbalances of UAV in strong wind or atmospheric turbulence situations and simultaneously rehabilitation of maneuverability and stabilization parameters without increasing flight speed.Thus, in order to upgrade the above mentioned parameters of UAV along with the gyroscopic momentum compensation it's necessary to increasing of the kinetic moment by means of gyroscope.This is achieved by installing the gyroscopes oppose to the propeller taking into account the gravity center of UAV (with rear-mounted propeller gyroscope should be installed in front sector), the direction of rotation of the gyro rotor is directed against the rotation of the propeller (the axis of the gyro rotor and propeller are in straight line); availing high kinetic momentum the devise becomes less subjected to the effects of the wind and turbulence; changing of the flight trajectory performed by moving axis of the gyroscope (stabilization and moments motors) and reductor, that fixed on moving shaft of the rotary frame, and the gyroscope is installed in a device to perform coincidence of the gyroscopic moments with the direction of the rotation of UAV. Coincidence of the directions of gyroscopic moments with the moments of the elevator and rudder increases the UAVs maneuverability. Stabilization and modification of the angular position of the UAV relative to the longitudinal roll axis is performed by increasing or decreasing of rotations of the gyro rotor with adjustable inertial moment.
