Thanks Cain and Cman, I am 99% sure its a blinky class, but TRCR is new to me so I am not 100%. I have contacted some if the guys that run there to get more information on the stock rules. I might look at a different motor to keep it simple for now, I have heard the SP esc's are a great value, I was looking at the LRP Flow, just seems overpriced, but they are nice.
