I meant as I'm going to be using emulation in this cab then perhaps I could rig something up to 'jiggle' the motor back and forth to emulate rumble .
For example if I hack a controller that has rumble then I could connect the rumble wire to a circuit with a relay to switch on a mono stable multi vibrator (anyone remember them?). That could flick the voltage back and forth causing the motor to run back and forward giving a rumble effect on the yoke.
For force feedback something similar where it try to steer the opposite way giving you a hard time to steer.
Wasn't there a hacked mame or final burn that had force feedback?
