"infinite-turn" pots
Pots are available off the shelf that have no stop at the end of the resistance element, and the element seems to extend further than the usual 270-290 degrees. I would worry that they might get a little noisy when used on drive axles, even more so on higher speed gears.
We tried an optical encoder system using the Banner sensors and black & white paint on the wheels, feeding a PIC. It proved unnecessary, and wasn't used in competition.
