Since I've got to build 25 copters for the University of Augsburg now, I've designed a small ESC mounting for the Rachel frame. The caps will later be fixed on the little arm of the mounting with a piece of heat shrink tube. And yes, the ESCs are upside down. I decided to rather have a clean wiring with the motor cables going undereath the ESC straight to the solderig pads than to have the LEDs on the top side. If necessairy, one can the the LEDs anyway.
