I went brushless with my M03. I used Hobbywing 35A ESC and Tamiya's TBLM-01 18T motor. I gotta say this set up is very nice for this car its very quick and has a lot of top end speed. And I could not beat the price I only payed sixty dollars for the motor and ESC. Very quick and the power comes on very even and smooth very good top end speed also.
