RE: lipos
James,
I am going to assume you mean a Minifan 480 sized Skyray. A 3S1P Kokam 3200 pack should give you around 375-400 watts of power with a run time of around 6-7 minutes, or more with throttle management. If you use the motor with a 4S pack, the Minifan 480 will produce too much load and would most likely burn up the Hacker B40-11S motor.
With the 3S Lipo, make sure you have a pack that can supply at least 45 amps or more.
