No need for a breaker, RC packs only put out 30amps tops, victors are rated for 40amps continuous, you'd cook your packs long before the victor went. Even if the FPs somehow stalled, something in th tranny would break first most likely. Also, there is no good way for an RC transmission/tires to effectively use the power of the FP motor... it's just too powerful.

I've made several FP cars, one with 4 wheel drive and 4 wheel steering, I think some pics are up on an old thread of mine. It had an attachable cart that could launch rockets and sported a wireless video camera with independent pitch and yaw.

I've been doing this sort of thing for 4 years now, and I've learned several things:
1) Victors can easily take 17v without the stupid cooling fan
2) FP Motors are sweet, but burn very easily when over-volted
3) 14.4V drill motors are awesome in RC cars(more torque and better power band than the FP) and they can be picked up for cheap at Sears/Sears Parts and Service
