ok i just ordered the motor mount to make sure i convert it to brushless lol. and yes i already stared on diff fluids. im going to be running 7-5-2 (i think could be 5-7-2. i need to ask him for a setup sheet) it was what was already in it from the old owner and he is a pro driver for mugen and had motos that where stupid in power so it should be fine for what im doing.
