I would say the two likely issues are.
Motor shorting inside. Open it and check for small burn marks. To open the motor you will need to remove it from the mount. Remove the motor pulley. Then remove the circlip at the Base of themails exposed shaft.
The fail safe needs to be reset on the remote.
Binding procedure as follow:
1).Check and make sure all the wires are mounted,and the remote is off, insert the bind plug into CH3(Bind) on the receiver;
2).Switch on the boards power, you can see the receiver red light flash;
3).Press and hold on the bind button on the remote and then switch the remote on;
4).You should notice the transimitter go from flashing red to solid red,and also the solid red of the receiver;
5).Once you see a solid red light, you now know the two are binded together,and please pull the bind plug out (do not turn off the power or touch the throttle) this is important, so the remote can record the throttle nutural position to set as the fail safe.
6).Then you can test it again by turning off the controller and it should flash. if you turn the power on Transmitter back on it should go back to solid red.
