Upgraded Zagi 400X.....now I need some help.

I upgraded my Zagi to the Promax 4014 motor, Jeti 250 speed control and Master Airscrew 5.5 x 4 prop. Problem is.....it gets HOT, HOT, HOT!!!! Now the motor seems to be sticking after running and the prop must be turned by hand before it will start again. Do the brushes need to be cleaned? Any suggestions would be appreciated. Thanks in advance.

My 4014 runs a little warm with a 1700mah battery. You are running way to small of a prop. The cobalt 400 turns about the same rpm as a speed 400 but can turn a much bigger prop. Step up to a 6 or 7 inch prop, pull a few more amps, oil your motor occasionally and hold on.
