RE: ganged servos and 14 mz
One of the guys in our club built a custom harness using DB-25 connectors (the same type that's used on a PC parallel printer port). He has a plane with four servos in the wing which (if kept grouped in sets of three) uses 12 connections of the available 25.
Six servos would use 18 pins. However, if you bussed the power and ground connections you could use a smaller connector (8 pins for six servos).
