The types of the first motor and the second motor are the same as the types of the adopted propellers, so that the sizes of the counter torque generated by the two brushless motors in the flat flight state are the same. The first motor and the second motor adopt a 70 mm-diameter bypass QF3027-KV2200, and the screw propeller adopts a 70 mm-diameter bypass twelve-leaf blade.
The model of the third motor and the model of the fourth motor are the same as the specifications of the adopted propellers, so that the sizes of the counter torque generated by the two brushless motors in the flat flight state are the same. The third motor and the fourth motor adopt Langyu third generation X2220-KV2200, and the propeller adopts GEMFAN Qianfeng 7035 three-blade propeller.

When the aircraft performs head-up pitching, the first motor accelerates, the thrust is increased, and the torsion is increased; the second motor is decelerated, the thrust is reduced, the torsion is reduced, therefore, the aircraft is pitching forward, and the fuselage is yawed clockwise due to different counter-torque generated by the blades at the front side and the rear side. In order to correct the influence of the positive torque, the fifth motor is required to accelerate, the sixth motor is required to decelerate, and the airplane is corrected in the anticlockwise direction. The fifth motor accelerates and the torsion increases; the sixth motor decelerates and the torque decreases, so the aircraft rolls left. In order to correct the attitude of the aircraft, the third motor is required to be decelerated, the thrust is reduced, and the torsion is reduced; and the fourth motor accelerates, the thrust is increased, the torsion is increased, the aircraft rolls leftwards, and the aircraft yaw anticlockwise due to different reverse torsion, so that the correction of the aircraft attitude is further accelerated.

In order to correct the influence of the positive torque, the third motor is required to reduce the speed and the thrust is reduced; and the fourth motor accelerates, the torsion increases, and the airplane rolls right. And the torque of the third motor is reduced, and the torque of the fourth motor is increased, so that the airplane is yawed anticlockwise and is consistent with the left yaw direction, and the correction of the airplane attitude is further accelerated. When the aircraft does right yaw motion, the method is opposite to the method and can accelerate the correction of the aircraft posture.
When the aircraft does left roll motion, the third motor accelerates, the thrust is increased, and the torsion is increased; the fourth motor is decelerated, the thrust is reduced, the torsion is reduced, therefore, the aircraft rolls leftwards, and the machine body is yaw clockwise due to different counter torque generated by the blades at the left side and the right side. In order to correct the influence of the positive torque, a fifth motor is required to accelerate, so that the thrust is increased; and the sixth motor is decelerated, the thrust is reduced, and the airplane does anticlockwise yaw. And the torque force of the fifth motor is increased; the torsion of the sixth motor is reduced, so that the aircraft rolls leftwards, and the correction of the aircraft attitude is further accelerated. When the aircraft makes right roll motions, the method is opposite to the method and can accelerate the correction of the aircraft posture.
