"Thanks Justin.

Here is my ESC:

Between VCC and GND is short circuit.

SMD component up of GND has left pin to GND and right pin to VCC (it seems to be an diode). Oviously tester indicates full continuity (00). I have desolded it and component is not in short circuit, and continues the problem between GND and VCC…

This is the only component that I can see between VCC and GND, but the component is not guilty.

GND track continues to 3 pins (down to up) of SMD component in the left with 4 pins (by side), and VCC continues from right of (diode?) to right of (capacitor?).

Here is my ESC with track painted:

I have desolded full IMU board and full WIFI/RF module, and short circuit continues.

Thanks!!."

There are six IC close to each the motor, these are the driver for the motor one of them is in short. I have the same problem, I remove several of these IC. But my motherboard have 6 IC in short.
