Bump box questions

[Blazer X]

I'm looking to possibly convert my hellfire to a bump box. Can someone here school me on the do's and don'ts. I'm looking at this one on ebay...http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=330222006515&fromMakeTrack=true

mugen box is aright, its jsut light. i don't like the dual motor boxes that use a belt to drive the wheel. they don't seem to be as strong as the klarge motor boxes
