Almost forgot...
To add the mess under the body, I installed two 5V fans - one for the ESC and another for the motor. They are driven by 4.8V receiver pack at the trunk. Hope this helps the ESC to stay a bit cooler when not going full speed.

Check out the rears, I've driven only four packs with the car...
Also, ordered one MaxAmps 11.1V 6000mAh lipo pack to save some weight from the 8Ah monster.
