What type of surface or track do you plan to run it on?
RACE or just BASHING around?
Oval L3 or the L3 'touring' on road car?
You'll find power to weight, etc. Pan cars are hard to drive with TOO much power stuffed in them, especially if you just plan to bash around.
These require a good grippy, clean surface.
We use just 2 cell Lipos with the SLOWEST Novak brushless motors (on a large track) and run over 50 MPH. With the 17.5 motors we're close to 60, and with 10.5's closer to 65.
A "faster" motor on a high bite track will be QUICK (if you can get it to get traction)
