I just bought a Axial scx10 and put a castle MMP with a traxxas 12t titan in it, just some stuff i had laying around. Well the motor is already shot and I an wanting to upgrade to the Tekin FX-R and one of the tekin motors but dont know which one i should get. I have some 3s batteries for my airplanes that dont get much use so i would like to use 3s. I have some 2s batteries also. What motor would be best for 3s? I mainly just crawl on dirt piles at my house and will be building a rock course also.
