well kershaw design has a nice one thats the one im going to get but im going to make another prototype one that is a little lower more beefier. but for 35 bux you cant beat it. so far i have heard if by the setup you aere going to use that it is a good one. if you use the stock 2 speed with reverse and mechanical brake it wont heat up or thermal as it is called; well thats what i have heard. i might go with a 7xl but not sure if it will heat up bad because i got a gearing chart and it said with that motor on 14 cells would go about 42mph. but i need somemore research to do. an 8xl would be maybe in the vicinity about mid to high 30 with 14 cells.and the battery mounts kershaw design has a complete kit for brushless conversions that includes them, but ussually people just make them to fit there battery configuration and what they use like mechanical brakes and such. here is the page check it out http://home.comcast.net/~milemarkers/index.html . hopefully this helped. and that is a cool body i wanted to get it for my maxx so i could use my titan body on my maxx but im going to sell the maxx instead.
