B73x Elevator Trim

Hi Guys/Gals

I am currently using a TM HOTAS as my controller and will probably continue to do so with my cockpit build as it is still relatively new and does the job for any plane i.e. fly by wire with joystick ;) - However, with that said I am still wanting to do a Elevator Trim setup etc etc... basically a TQ without the throttles - WITH flap lever, speedbrake, etc etc...

So the question is, the DIY'ers - how have you accomplished the indicator? i.e. if you trim up for takeoff and you trun your wheel what sort of mechanism hav you used to indicate trim level? have you used multi-turn pots, psydo (12 way rotary switch) encoder etc etc...

Thanks in advance.
