Hello again.
A small update of my project (a part of it... ;))
Here we go, my A.A.P.D.B. - Alternative Arducopter Power Distribution Board
Simple double-sided board with extra kick.
It can handle 4 ESC's and a battery monitor. And the most important high current!!!
Above is the board before etching.
As you can see the board is VERY simple but there are some cool features:
1. On the top side of the board there is a mesh connected to negative pole for ground providing and it acts as shield for PWM signals and for other electronics above the board like the APM, compass, x-bee, GPS etc...
2. Small 2 pin connector for direct battery connection, good for LED strips and battery monitors like this one from HobbyKing
3. All 4 PWM signals combined in ONE socket as well positive and negative wires from ONE ESC.
4. And 4 mount holes.
Some more pics from the making process:Etching!!!

regarding inputs of the becs, I'm not entirely sure of the components involved, but for example on my rangevideo osd, it has dual power inputs and with a jumper setting it can be set to auto switch between the inputs, choosing the better voltage level. so if one dies...:( the other takes over automagicly and output power doesnt even see a bump. I also saw the dual bec on hk as well, so couldnt be that much involved, but I'm not that good on electrical engineering so wouldnt know where to begin. Really I was just wondering if you had intentions in that regard, since I see power input pins on all 4.
Hi,
Looks very nice, certainly an improvement over my mess :)
I'm curious why you only connected the signal wires on the ESCs and not the ground?
I agree with not hooking in the 5v, but it seems to me that 3 of the ESCs have no ground reference this way?

If just happens that one ESC blows, your pretty much dead in the water yes?.
