k so i got the tax returns and the emaxx is going to get rebuilt. I currently have a mamba max controller that was handed down to me. Im not looking for insane speed 30-40 is ok. I would like to stick to a normal 1/8" pinion size. i looked at a 540 9l with an 1/8" shaft. Any suggestions on motor or if i should go with a different controller setup. thanks in advance
