so, gear them back up... they're plenty powerful. I just looked at
T081... he used ATV starter motors for his tank, and at 12v it ran too
fast. He had to run it on 6v to go slow enough... sounds like a
definite motor possibility.
why not just go with the M-01 (?) motors that some of the guys in here have been using? they all ready have been geared downChris
