With its low profile design, strong torque and precision movement, the HS-75BB 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). If you require a proportional servo this size, use the Hitec HS-77BB.
