Dynamite Fuze ESC and 5800kv motor with 3s 5000mah. Very impressed with the performance of the motor/esc for $110. Motor has pulled 66.8 amps @ 11.74 volts = 784 watts. I have it geared for speed runs 90+ mph, so I can only make a few passes before I have to let it cool down. I can go down to a 14t pinion which will still give me low 50's on 3s, temps will stay around 130F with this gearing for 15 minute run time. It's a dynamic conversion that with allow alot of motor, battery and pinion options.
