I am wanting to buy a brushless motor for my Stamped but I am so confused. What is the difference in speed between a 3300kv motor and a 4800kv motor, using the same ESC and LiPo set-up? I know a guy who will sell me either one for the same price. I was told that the 3300kv is from a rc10t4.1 truck and the 4800kv is from a speed-t. He is going to sell me an Associated XP SC450-BL Brushless ESC with which ever motor I pick for $50. A deal that I don't want to pass up. Everything is new, but I don't know which motor will be faster. Any advise would be greatly appreciated.
