"Hi Florian

"Hi Luc
I had a simalar problem to you with the APM 2 it was to do with the 6 pins not soldering the connectors properly on the top GPS board (my fault), after I had re-done the connectors all worked fine.

"Hi Gerry
I am about to do a very similar thing to you except I was going to use a OPTO ESC which gets around any potential  noise issues but answer your question do not connect the return (if your ESC has a BEC) shown in your diagram"

Can any one say if there is any advantage of shifting the mounting the motors 180 Degs from where they are at the moment, I appreciate a change of prop is required but I have seen a few Quads / Hex's with this config and they explain that it's…

"If you were using the 5S 5000 mAh in you tests with the 880KV motors did you use a different ESC than the standard 20A 2-4 LiPO that ships (ArduCopter ESC 20 Amp) ?"

"Can I ask a fairly simple question regarding the merits of all Carbon Fibre vs Aluminium in Quads, Hex's etc
