# Feedback Servo
|
|
Feedback servos have a fourth wire that sends the position information of the sensor back to the controller. It is the same feedback information that the servo uses internally to do the PID-position-control.

# Reasons

1. Initialization: when we start the Flight controller it will initialize the servo signal to the PWM value specified in the `PWM_MAIN_5_DIS` parameter. If the servo is physically at a different location during startup it will slam the servo to the correct position which is a large strain on the system (servo as well as mechanics) and will result in a large vibration.
