I want your help. I am having a 330mm quadcopter with 4 a112 brushless motor and yellow esc yesterday all were working fine ( using kk v 2.1.5 ) all of sudden today when i turn my quad on the fourth motor wont spin and esc will beep and beep .
I checked the esc sepratrely in my rc plane and it was working and i tried different esc in that position ( red simon k ) but motor wont spin ( it is working in my plane but not in quad ) i think there is a problem with my signal wire but i have checked them all
Plz help :salute: :hatsoff:

Did you check your motors wires with DMM? does it show continuity?
Just check if there is any problem with signal. KK 2.1 internal signal connection might have caused the issue.
Try putting some other working esc+motor combination in non working output channel. It might give you some idea aboout what's wrong.
The issue might be a simple calibration fault. Please check if the motors spin properly when calibrated.The kk might not be giving the base initial pwm values so it isn't initializing. Good luck and please keep updated.

1. I checked the esc sepratrely in my rc plane and it was working
2. and i tried different esc in that position ( red simon k ) but motor wont spin
3. ( it is working in my plane but not in quad ) I presume you mean the motor
4. i think there is a problem with my signal wire but i have checked them all

From the above it seems that
1. ESC is ok
2. Motor is ok
3. Motor won't run in the quad even with a different ESC
Try this.
1. Disconnect the other three motors from the FCB. (Say #1,2&3)
2. Plug this motor/esc (say #4) into one of these vacant slots in the FCB. See if it runs.
3. Connect one of the other motor/esc combos into the FCB slot presently used by #4. See if it runs.
I presume you had calibrated the throttle for the motor/esc individually for all four.
PLEASE REMOVE PROPS WHEN TESTING. DO NOT HOLD BY HAND WHILE TESTING WHEN PROPS ARE ON.
