I did read that Neu's motors aren't really designed for cars, just planes/helis/boats. But it would be interesting to see the power of some of the larger ones. With a powerful drive train it'd be usable I guess -- it's in an Emaxx on youtube, which seems to be 100% driveable and controllable. I don't know why though.

Anyhow, it would indeed cost tons of money. I think the Flux chassi would handle it, maybe I'd need stronger drive trains though. The comment about backflips was a joke.
