The MKS HV69 is a metal gear high-voltage digital micro servo with a standard 6mm 25-tooth output spline. Running on 3.7–8.2V (1S–2S LiPo), it delivers 141.7 oz/in (10.2 kg/cm) at 8.4V with a 0.10 sec/60° transit speed — delivering impressive torque and speed in a compact 21g package for small aircraft, gliders, and micro RC applications.
A coreless motor with direct-drive potentiometer feedback delivers consistent centering and responsive performance. Metal alloy gears provide durability and strip resistance. Dual ball bearings ensure smooth, consistent output shaft operation run after run.
