I drilled out my 5mm pinion.. with a 6mm metric drill bit...(or you could get some gears from sdp-si.com)

Same mounting pattern as a 22' series motor.. (30 mm)

I think it would kick @ss in a truggy... using a feigao would save you 200 grams..

I wouldn't stick this motor in a E-maxx... unless it's bullet proof.. :)
