Cables and more cables.

Finally silicone cables have just arrived. Now I can solder the connectors on the cables to connect all speed controllers (ESC) to the battery. I'll cut four red cables (0.75 qmm) that will connect a red cable (1 qmm) that will connect to the battery. Then I will have to do the same for the black cable. I also ordered the cable to connect the receiver connection from the speed controllers to the arduino board, but came with the wrong colors, orange, red and brown, but what I ordered was black, red and white. After some research on google I found that the colors depend on the manufacturer of the radio control (R/C). So the orange, white or yellow color is the signal (Pulse), the red color is the Positive, the brown or black color is the Negative (Ground). For the quadcopter I just need the white cable (orange or yellow) and the black cable (brown) from the all speed controllers.
