which motor?

[revo madnesss]

hello,

i have been searching for hours on end for a setup for my hhh converted buggy for bashing with no avail. im looking for a motor which will reach around 65mph on 6s or 4s if possible . since im not going to be racing and just bashing i reckon the temperatures will be lower as the motor will not be used to much as brakes and the throttle will be more continuous.

thanks for your help
