Some ESC and motors are only made for 3cell lipo's so with out knowing what the ESC is capable of and its limitations its hard to know if it will be damaged or not.

I very much doubt you could run the stock motor on 4s - since you a stuck with the fixed size fan, you cannot "prop down" to lower amp draw, and I'm sure that you'd exceed the 9-10A limit for the motor.

Hey Dr Kiwi I didn't know you were on RCU also. I guess I am assuming you're the same Dr. Kiwi on wattflyer.

Yeah it wouldn't take much to over amp it with a 4 cell lipo if the motor limit is 10A.
