rustler vxl replacement motor

[scarletboa]

i think the rotor is the part that is still good in the motor. it still runs smooth and if it didn't draw so many amps, it wouldn't be a problem. i usually get about 15minutes of runtime of my cheapo tenergy packs but i get about 5-6minutes now and it killed both of my tenergy 3800mah packs. (they only cost me $17 each though)

the can of the motor is dented. is it possible to get everything but the rotor?
