LRP Sphere and Feigao 8s motor...

[RC-Monster Mike]

The 8s won't draw as much as the 6s. With the right gearing, the 80 amp will work just fine with the 8s motor. The120 amp will be pretty foolproof for this motor. For less than 8 cells, the warrior will need a receiver pack, which is why the MGM controllers are recommended. If you don't mind a receiver pack, the warrior 9920 controller will work excellent.
