I 3D-printed a trim wheel for my piston/turboprop throttle panel. It’s a bit on the big side but it works well. When I do the next major iteration of the sim I’ll make something a bit more custom (ie I’ll design it myself rather than using an existing model). It (and the switches and buttons) on that panel are wired up via a Leo Bodnar MicroBBI board, which is tiny but still has room for wiring 20 buttons or 10 encoders (or a mix) and one analog potentiometer axis.
If you build cockpits and you haven’t heard of Bodnar, definitely worth checking out. Arduino is fine but often overkill for simple applications, Bodnar cards just look like HID devices to Windows (usually a game controller) so they work with everything without programming.
I’ll have to build another trim wheel for my jet throttle panel, currently based around Thrustmaster TCA throttle quadrants/s but soon to be based around this custom Throttletek A320-style TQ I recently took delivery of. Should be a fun project.
