Hitec HS-45HB AGTT Feather Servo

The Hitec HS-45HB AGTT is an ultra-lightweight feather-class servo designed for precision control in weight-critical RC applications, delivering 4.6 kg-cm torque at 6V with minimal mass of just 9.7 grams. Professional RC aircraft builders, drone enthusiasts, and precision roboticists rely on this servo for applications where every gram impacts flight performance and battery endurance. This servo solves the critical engineering challenge of balancing control authority with weight minimization in small-scale aerial platforms and compact mechanical systems.

Product Overview

The Hitec HS-45HB AGTT operates on a standard PWM control protocol, accepting 1000-2000 microsecond pulse signals from RC receivers or microcontroller outputs. The servo features a coreless DC motor design that delivers exceptional speed and efficiency while maintaining the compact feather-class form factor. The AGTT designation indicates this model incorporates Hitec's advanced gear train technology with precision-machined brass gears that reduce backlash to approximately 1.5 degrees, ensuring smooth and accurate positioning critical for aileron, elevator, and rudder control surfaces on ultra-light aircraft.

The HS-45HB operates across a 4.8V to 6V supply range, with performance specifications optimized for 6V operation delivering 0.12 seconds per 60 degrees rotation speed. The servo features a sealed case design that provides protection against dust and moisture ingress during field operations. The lightweight aluminum case combined with the coreless motor architecture makes this servo ideal for applications where servo mass directly impacts system performance metrics such as wing loading, hover time, and maneuverability.

How to Use

Installation of the Hitec HS-45HB AGTT requires connecting the servo to your RC receiver or microcontroller using the standard three-wire servo connector: signal wire to PWM output pin, power wire to positive supply (4.8V to 6V), and ground wire to common ground. Ensure your power supply can deliver sufficient current for servo operation, typically 500-800 milliamps during active movement. Mount the servo using the provided mounting brackets, positioning it to minimize mechanical play in the control linkage and ensuring the servo horn aligns properly with your control surface attachment points.

Configure your RC receiver or microcontroller to output standard PWM control signals in the 1000-2000 microsecond range, with 1500 microseconds representing the neutral center position. Perform a servo range calibration to establish minimum and maximum travel limits that match your control surface requirements, typically 80-100 degrees of total rotation. Test servo responsiveness with smooth, deliberate control inputs before flight operations, and verify that control surface movement direction matches your transmitter stick inputs. For optimal performance, keep servo leads as short as possible to minimize signal noise, and consider adding a 0.1 microfarad capacitor across the servo power leads to filter electrical noise from the power supply.
