you probably don't need to mount the 180 motor on top of the 130 can. Does anyone know if there's any way of using the stock spindle in a 180 can? I would personally just mod the chassis to run the 180 as a 2wd motor, like mde's buddy! I have a Speed 300 motor lying about, and all this talk has got me thinking of doing a similar mod ...

How about using a stock shaft and an empty can (no armature or magnets, maybe just use the cover), and putting a 36T gear on it (or something similar as long as it's as big as possible without interfering with the ground etc.) You could then stcik a 6 T pinion gear on the 300 motor, and see how that works. I think this is the setup used with the Xmods, but I havent' got one to verify.

This wat the motor has less work to do , as there's more reduction, so ther should be less heatingand stuff...
