The 3300kv that comes in it is definately not equivalent to a 17.5 turn motor. More like a 13.5/10.5 turn. The first track I raced at made me run in the mod class with that motor, did alright to. Each track is different though. I would bet for pure speed, you would have a bit on most guys that are not running excess timing or boost on a normal 17.5 turn motor.
