The other post is weak...
Our car has 2 pots, one for power one for headlight dimming.
The car runs on 3 150mA batteries and looks completely stock from the outside. The pots are tucked nicely above the axle. Just pop it out, tweak the pots, snap it in and roll.
With a 1.6 engine and blue gears it screams by dual cell bits with 3.8's all day long!
