    Question about Cessna trim wheel

    Hi,
    I'm building now cessna 172 trim wheel and I want to use a potentiometer for trim level regulation. But potentiometers are rotating only in 275 (or 270) degrees so what do you think? It's will be ok or I should use gearwheel? or maybe use encoder instead of potentiometer? The simulator will not be an exact replica of the Cessna 172 aircraft.

    Look at my project:

    Sorry for language mistakes

    Thanks for reply

    You need to use a 10 turn pot like this one. I use one of these for my GA trim wheel, and it works really well

    Re: Question about Cessna trim wheel

    Are these 10 turn pots seen as an axis or button clicks like a encoder?

    Cheers,

    Hi Alex,

    10 turn pots are just like regular pots electronically so they will appear like an axis.
