Anyone used a Neu 1900 series in a Car/Truck?

After looking at all of the Neu options on the cc site, I wondered if anyone ever used the 1900 series neu motors for a land rc vehicle? They appear to have a large diameter rotor, and are good up to 30k rpm. Kind of like a mix between an inrunner and an outrunner. The vehicle would have to be geared differently, as the motor would turn less rpm, but make more torque. Wonder if the larger models would be able to do a direct to diff setup?
