hi adb140275
i have the motor you want to buy in my revo 3.3 conversion with this heat sink:

and it works great.
The motor gets very hot because of the low efficiency but with the heat sink thats no problem.
A friend of mine converted a savage to a savage flux, with flux chassis, flux motormount and so on and he simply cut the heat sink in length.
But a motorclamp is THE way to go because i already messed up 2 of the 4 threads of the motor. lol
