Compact Aircraft ControlMicro Servo with Maximum Precision
The Hitec HS-45HB Sub-Micro Servo delivers unmatched precision and durability for lightweight RC aircraft. Engineered with high-strength Karbonite gears and a top ball bearing, this featherweight servo ensures smooth response and accurate control surface centering.
Engineered for Micro FlightHigh Centering Accuracy for Aircraft
Designed specifically for ultra-small applications, the Hitec HS-45HB is an excellent choice for indoor micro models, hand-launch gliders, and Speed 400 electric park flyers. Hitec redesigned their micro servo housing to mount the potentiometer directly to the circuit board, maximizing space efficiency and structural integrity. Paired with a top-supported ball bearing drive and durable Karbonite gear train, the Hitec HS-45HB servo delivers the incredible centering accuracy required for responsive aileron and elevator control. A special 2-inch long control arm is also included for 3D flight setups requiring extreme surface deflection.
