Product Description: 
Servos works well in the range of 4V-7V. The signal is supposed to be at TTL levels. Usually, servos are run near 5V, for both power and signal high. The design principle is that the planetary gearheads module drives the rudder plate to rotate. The control circuit board receives the control signal from the signal line and controls the rotation of the motor. The motor drives a series of gear sets to decelerate and transmit to the rudder plate. The output shaft of the servo motor is connected to the position feedback potentiometer. The position feedback potentiometer is driven while the rudder plate rotates. The potentiometer will output a voltage signal to the control circuit board for feedback, and then the control circuit board will determine the rotating direction and speed of the motor according to the position, thus stopping the target.

When the aircraft model needs to tilt, the servo motor is manipulated to tilt, and the swash plate connected to the servo motor through the tie rod immediately tilts. At the same time, the steering wheel arranged on the swashplate, the main propeller linked to the steering wheel, and the lower plate linked with the main propeller, the upper plate arranged on the lower plate, and the auxiliary propeller linked with the upper plate also tilt synchronously to change the tilt direction and complete the tilting action. Even if it is subject to external interference, the original balance can be restored in time.
