Title pretty much says it all, but for context, I'm trying to make a gimble turret using an aeroworks joystick, swivel bearings, and analog transmissions so that the pilot can finely adjust the turn rate or speed it up by pulling harder or softer on the joystick. The problem is that the joystick outputs an analog signal of 0-15 and for whatever reason, analog transmissions (when powering the gear, not the shaft) just stop working if they receive an input of 15. So, I'm wondering if anyone has a clever work around by subtracting 1 from the signal input somehow or if anyone can tell me how to make this work in a different way. Any advice is appreciated. Thanks!
