If you want a better motor than the mm 4600 use a feigao long can, like a 10l or 9l. an 9l will be good on 3s the 10l I have works fine on 4s. I would not suggest 2s as the motor you will use to get the necessay rpm will get hot and draw alot of current. I highly recommend the ls10, it is a great truck. I almost wish that I had not bought and converted a crt.5 as it was much more expensive and not that much better. I am sure that the difference would show on the track, but all i do is bash!!!
