At the moment I have a tamiya wild dagger (2 gearboxes, ft and rr) running 2 traxxas 12t titan 550 motors. I am currently using a novak super duty esc and running it on 3s lipo. It is reasonably fast, 32mph IIRC. Runs fine and the motors say decently cool with some clip on heatsinks. Plus the traxxas motors are only rated for 8-9v but the work fine on 3s. Tons of power too!
