Congratulation on this built and your succesful maiden run.

Interesting motor choice, as it is rather lightwheight for the wheight of the car. With 3KW peak not the most powerfull one but as one can see in your videos with 2wd too much power will only spin the car. Motor temp in your videos was around 49-58°C (120-136°F) right? I guess your outside temp was at 12°C / 52°F while you made this run. With a more agressive driving style, 9s Lipo, a more powerfull ESC and hotter outside temperatures your motor temp might become critical.

7s2p A123 are able to provide far more peak power then 1.9KW. I would assume up to around 2.8-3.5KW peak which also represents the rated motor limit.

Expect considerable more power with 9s lipo which is comparable with an 11s A123 setup.
