ok i got a new brushless crawler motor for my tamiya semi. shouldn't be a big deal right? well knothing ever work first time with me! ok i plug it into my dyamite fuze esc, great esc never had problem with it. but is spins backwards!
i switch one of the wires like on other esc's and it run forward but if i add full power fast it spins and locks up! but if i add power slowly and smooth it runs fine. i thought it was something in the gear box but no it's in the motor i can spin the wheel after it locks. i really realy don't want put my castle side winder in the truck is very big and kind of beat. any idea why its doing this? the motor dosen't have a brushed/brushless mode it just how you set the wire's
