I have converted a Luscombe manual trim to work with a linear actuator. 12v.

Momentary rocker switch on control stick.

While the internet abounds with circuit offerings, I am aware of

potential "noise" elements and there are probably a few best practices

to adhere to.



Any circuit suggestions appreciated.

Best...

How about a full-bridge motor driver module?

I built a module very much like this one to buffer the trim signals from my Dynon autopilot control panel (2A current limit) to the elevator trim linear actuator in my Kitfox (about 7A max).
