Application(s): Sailplane Flaps + Elevator (3.0M to 3.8M wingspan). Throttle and Choke on a 42% IMAC airframe with 150cc gas motor

Comments: These are solid servos and what other manufacturers should use as a benchmark for servos in this class for both reliability and quiet performance. I use these on the flap and elevator surfaces on my 3.0M to 3.8M wingspan composite sailplanes as well as on my 42% IMAC planes for throttle and choke. Smooth consistent response from this servo.
