Hitec HS-75BB

Low-profile power of ≥ 23 mm Class

Rugged HS-75BB Low Profile Servo specifically for retractable undercarriages.
The servo is not operating proportional, but runs without interruption slowly from full scale to full scale (180 degrees).
The HS-75BB analog servo impresses with its three-pole brush motor, elastic nylon gears and with a ball bearing on the output shaft, which is particularly suitable when low clearance and high positional accuracy are important.
