Is there a 1/10 electric 4wd stadium truck?

The Feigao 6s isn't a great motor, it sucks amps like crazy, especially on 8 cells. The Mamba Max 5700 system has too high of a kv IMO, it's better for lighter 4wd vehicles (like 1/10 4wd buggies and 1/10 4wd cars) and 2wd cars/buggies/trucks.

You seem to be thinking that the higher the RPM/kv the better. That isn't always the best choice. For good efficiency, it's best to keep the motor spinning at about 40,000 RPM max, and for the HPI MT2 it would be best to use a minimum of 8 cells to get there (a lower number of cells won't make it seem all that great).
