thanks for the reply Joe, do you know the diameter of the brushless motor fumotec? Since I posted this I've have had one arrive from hobbyking, it's a 2830 1000kv so at 12volt it's spinning at around 12000rpm, only problem I really encountered when doing this was the pinion, any idea where I can get a 3.17mm pinion for the mfa planetary box?
