Perhaps Brett in the simple configuration on a fuselage thats fine. However even in simple airplanes and it really is not even related to size with the ever increasing popularity of wing servos (and thats great) There is always the associated problems of the extensions of the wing servos with buried inaccessable plugs and even the difficulty of just pulling the plugs through or partially into the wings.

Adding more plugs than neccessary will increase resistance no matter what grease you use as opposed to a single run of proper Length wire and thats something I care not to do. So even on the small simple ones that have any wing servos (aileron, flap, throttle or gear) I cut the new servo lead in half and add (usually heavier servo wire agine for less resistance) that will give me the perfect length at the fuselage joint to connect to a short extension to the Rx. Only one plug for airplane assembly purposes and no more or excessive lengths at fuselage/wing joint to be wadded up during each assembly.
