It means that the motor has been damaged by water or any outer substance thats why your motor is turning only in one direction.You have to change the motor.

If you are to soar high remember to look up......



Hello man.

I suggest that you check the driver circuit for faults like broken or a crack in the Mosfets which directly power the motor.......then you can change those Fets........if the motor is a brushed one then it will be even easier........just check the Fets which are not powering up with ~20V setting on a Multimeter.
Good luck!

Regards,
Partha.

Get it to a local electronics repair shop. They will be able to help you out. Very difficult to troubleshoot chinese circuit boards from just pictures.
If you are ok with soldering just desolder the motor terminals and then directly hook it up to a battery to check if the motor and steering assembly is fine. Then you can put a multimeter on the wires going to the motor and use the remote to see the voltages..
