This pretty basic test has been recommended also in the RC Groups forums – all you need are some wires, isolation tape and a knife. Of course you need access to the motors and ESCs suspected.
Knowing that most of the quads have CW and CCW motors (usually marked as A and B) we can easily take advantage of this fact. These motors are usually opposite each other. In my case I will “swap” the back right with the front left motor.
You may apply this troubleshooting technique on almost every quadcopter that has brushless motors.

Mine was a burnt esc, had to swap the motors to find out. You may need to apply solder to get it to work well. Still waiting for my new ESCs to arrive. I recommend changing the motors too when you have a burnt esc
Nice way to check between the two components, though for me, I am just going to replace both the ESC and the motor on my Bugs 3 for 2 reasons:
1. Parts are fairly cheap.
2. Most important reason, if the faulty ESC or motor has a short circuit, you may blow the good ESC/motor that you are testing.
Cheers mate!
Is it available in India?
And what is the cost?
doez this thing only take stock motors or escs or can i use like 20/30 amp eacs?
another goody… hope you get er in the air soon!
how about a link to esc’s?
nice video brother
