I used gaint scale RC servos for the autopilot for the 2 years that it was install. but now I have been using servos for elevator trim and they are higher quality and can be bought for use when using the RC square wave pulse train that I used in the autopilot . Used these in the SSSC and the JMR for electic pitch trim with the model with limit switches. Power is 200N.Pops, what kind of servos did you use for the auto pilot trim tabs?
L16-R Hobby Linear Actuator - Plug and play with RC recievers. Ideal for Radio Control, Robotics and Arduino.
Please, what does SSSC stand for?
