ground loop?

[EgonW3]

I am installing SBEC to power servos of my gimbal. There is a wiring diagram of such an installation on AeroXcraft website: http://www.aeroxcraft.com/images/p0005_05.jpg
I just wonder if such a wiring doesn't create ground loop. Shoudn't I disconnect "0V" wire from BEC to GND wire of servo or GND from F1 and F2?

On the contrary - those connections prevent a ground loop. When using multiple voltage sources you always must make sure that everything shares the same ground.
