A couple of pages back I noticed that someone said that length of the wire does not matter. I think they misunderstood some people. Being that I worked for a company that builds high end computer boards, and since I was repairing and debugging the prototypes, I can give a little more insight on this.

The length of the wire does matter in the fact that the longer the wire, the more voltage drop you have because of the resistance of the wire itself. That is also why your ESCs use the bigger wire. It allows freer flowing of current to the motor, etc. Too small thickness of wire and you would be "choking off" the power you have. Bad solder joints (too much solder flux or gloppy solder "cold solder joint") will do the same thing. It increases the internal resistance of the contact, thus robbing you of power.

It may say tech rookie, but I know my electronics.
