The low budget DIY XL conversion

Looking good so far! Everything I have read or heard about the KB45 motors has been positive, with the only slightly negative thing being the 6mm shaft, which makes finding pinions a bit more difficult. But, most people either drill out 5mm pinions to 6mm or mill the motor-shaft down to 5mm.

i milled the shaft on my kb motor with a standard dremel bit. all i did was hook the motor up to the esc and spun it slow while grinding the shaft to 5mm with my dremel. all you have to do is eyeball it and check the size often with a 5mm pinion gear. then, all you have to do is grind the flat spot.

btw: you will need a custom motor mount. the kb motors have 30mm spacing and 4mm screw threads.
