RE: Servo extension wire?
Good grief Lynx,
#24 guage has 27.3 ohms per 1000 foot = .0273 per foot so even if you are talking about a 24" extension actually having 36" of wire you are only talking about an extra .0273 ohms of resistance.

Actually a pretty good case to use #22 guage for twisted cables if your going to worry about it.
