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!!!

Washed...

And cleaned....

I decided to post and share of my ArduCopter frame build process.

It's "hand made" folding frame, the design is adopted from: Jakub's Frame 

90% aluminum parts (The landing skids are temporary and they installed for reference only)

The center plate dimentions 120*120 MM  X configuration.

Fold is done by two steps: 

Thats all for now, more updates soon.
