Trim Actuator

Published by: Bill Chance on 25th Jun 2017 | View all blogs by Bill Chance

Need to hook up a llinear actuator for wing trim.  It's from Revo made by Duff Norton.  Can't find a wiring diagram from Duff Norton.  It has five wires coming out of it.  Three of the wires are hooked to an internal potentiometer and two wires go to the motor.  This unit was never installed and has been packed away for a number of years. The simple wiring diagram from Revo just shows two wires running to the actuator from a double throw double pole switch. Don't know if there should be more info. Running power to the motor wires runs the shaft in and out and my question is the potentiometer just used for motor position control purposes and it's not needed in this application.  Those of you that have the wing trim actuators are there just two wires running to it?  


I think Larry is out of pocket right now.

    Hi Bill, you should've tried me. :-)

    Yes just run the two wires to operate the trim. It sounds like you already have the switch wiring diagram. The motors that we now use do not even have a potentiometer.

    Thanks Larry. I'll get it hooked up.
