They aren't quite the same though - the Slayer wheels have a larger ID at the inner-most part of the wheel because they have to clear the Revo knuckles. And I they should also have a 14mm hex.

xcntrx: RCM Mount. My Finned Feigo 7xl got up to 150F, 120f on MM. Not too bad IMO. No 1st gear & motor brake will add to the heat tho. Driving last night I never hit top end in about 400 feet or so. It was shifting at around 40% throttle and flying at 80%. Let me know how it goes for ya.
