I have an LRP dynamic 10L 4700kv in my Hyper Sc10 that is an animal. I bought it used, had a whole season on it, and it freaking screams. You can't run a lot of timing on it because of the way it's wound, or it gets hot. But even at 3 degrees constant, and 5 degrees boost, it is an extremely torquey motor.

I just put a Flash (Nitrorcx) 4800kv 2 pole in my son's slash 4x4, and it is impressive as well, and cost 32 dollars. It is almost as fast as the LRP motor, and I haven't even gotten to fine tune it cause I don't have the program box for the ESC
