Hi, I need help on how to connect external BEC to power up the wkm system.

I got these problems since I got my wookong. White Lights and Drifting.
I have read from Boris post that the drifting is due to broken/defective PMU.

I already did everything - swapping motors, calibrating esc, rechecked imu and gps measurements
repositioning imu and gps, used the longer rod for gps mounting, compass calibration before flight, etc.
but the white lights and drifting wont go away.

So now I want to test by connecting external BEC to power up the wookong.
But I cant find any drawing or diagram online.
I would appreciate your advice regarding on this matter.

Thank you so very much!

By the way my setup is Hexa "I" and gimbal is activated with hs-225bb servos. Voltage protection monitor is off. FW 5.02

I tested without gimbal just the craft still drifting.. :(

According to Boris the MC is powered with one of the BEC's ESC and this solved the drifting problem.

I'm completely lost please help...

If the MC is powered with one of the BEC how about the power output from PMU? there are 2 power outputs do I need to disconnect one of them? which one? Does one BEC is enough to power the whole system?

By the way here's an old post of Boris
