Hitec HS-75BB Retract Landing Servo

Designed specifically for the landing gear of aircraft.

With its low profile design, strong torque and precision movement, the HS75BB is a great choice to move your retract gear in a realistic manner that you need. Note, this is a retract or “bang bang” servo and only travels from one end to the other (180 degrees). It operates like a two position gearbox and not like proportional servo.
