Way Fast and a little hot!

I just gave my first BL set up a run out of the livingroom and into the dirt.....HOLY COW! I have never controlled acelleration like that! It was about 1/4 - 1/3 throttle and when I hit it - it flipped!

The controller and motor is getting hot - I measured 120F on both, but that was after a little cool down. Here is the set up:

12020/8 XL, 20T pinion, 51T strobe slipper, 12 cell IB 3800 (which are awesome!), UBEC, stock receiver/tires/diffs/trans, MIP CVD

Do I need a smaller pinion to keep it cooler?

Wow! What power!
