AGFRC A80BHP-H 18.5KG Ultra-Fast Brushless Digital Tail Servo with Steel and Titanium Gears 666Hz PWM Control and 25T Spline for 550 to 700 Class RC Helicopters
➤ The AGFRC A80BHP-H Tail is an ultra-fast brushless digital servo designed for responsive tail rotor control in RC helicopters. It delivers up to 18.5kg-cm at 8.4V and reaches 0.030 sec/60°, providing rapid yaw-control response for demanding flight applications.
➤ With 666Hz refresh rate, FET drive, strength steel and titanium gears, an aluminum case, metal bearings and programmable PWM control, it is built for high-response tail systems. Its 90° ±5° travel and 452–1072μsec signal range make it a candidate for 550–700-class helicopter tail applications after verifying gyro compatibility, mounting and power requirements.
