Hi guys, I am having a problem with my Turnigy AE 25A. I bought 4 of these ESC to use on a quadcopter, and 2 of them are really strange. They used to work just fine, but when I was trying to set the PI control on the flight control board, they suddenly stopped working correctly.
The problem is, let's suppose I turn on the motor with the bad ESC, the motor will spin, but at low throttle the motor seems to go back and forth and then stop. If I put full throttle the motor will spin. If I put a propeller on it, the motor will not spin. I have tested those motors with the working ESC, and worked just fine.
Here is a link on YouTube where you can see the bad ESC:
And here is the same motor with the good ESC:
Anyone has any idea why this is happening?
I think that might be due to some bad FET or bad connection, but I am not sure.
Thanks.
My parts:
Flight control: kk 2.1.5 (from Hobbyking)
Motor:4 NTM 800KV /300W (from Hobbyking)
ESC: 4 Turnigy AE 25 A (from Hobbyking)
Radio: Hobbyking 6ch (from Hobbyking)
Battery: Turnigy 5000mAh 4S1P 20C (from Hobbyking)
