Have a look at the hyperion range. The larger models will easily handle the current. You really need a motor calc program. Motorcalc do a 30 day free trial which will help you. Try allelectricrc.co.uk for a vortex 63/62/286. I have no personal experience of these. A dualsky 63/60/ca12 from alshobbies.com might be a better bet...the specs are on their website.
