It's all so HOT!!!

The problem isn't the batterries. 10k mah 10c packs are more than enough. You can't look at the "25c" number by itself - the pack capacity is part of the equation. The packs are good for 100amps continuous(and TrueRC packs are rated conservatively), which is plenty for the Novak system.
Its summer, and he is using the largest suggested pinion gear and thermalling after 14 minutes - no big surprise, really. Gear it down and you will lower heat, increase runtime and likely avoid the thermal shutdown. The Novak systems like small pinions for best success.
