thanks for the response. but i have a few questions on that note.
whats the diffrence in the 7xl, 8xl, 9xl and the 10xl? 10 would be for raw torque and no speed, 7 would be all speed? but run hot? this is the knowledge i am getting, but would prefer to hear it from you, one who has them.
DickyT did some calculations lastnight for me. running my spc 7 cell 460's, 5.5mm tires and whatever gearing he picked, i could get 45 out of the 8xl.

this is right around where i wanna stay. i do NOT want the motor to start to get hot and have to worry about it busting on me or anything.
