Hey Skeeter and Cotman,
I tried using the "Molex" plugs/connectors on my warbird. Have to hook up ailerons, flaps, gear and bombs...
The molex plugs did not come Gold Plated and after a couple of flights I was getting real bad "jitters" in the wing controls (flaps showed the worst). The plugs were from a good electronics store, I figured they would work great... Nope[

]
I switched back to gold-plated aileron extensions and added color markings on each lead - no more problems and it is not that big a deal to plug in 4 instead of just one.
I spoke with another scale guy who said that the "regular" (not gold) electronics connectors either get corosion fast or do not hold up well to the vibrations. Even with a clip to secure the plug, they developed the glitching..
So, just from my experience - you can't go wrong with gold aileron extensions and I'm not trying the Molex experiment again.
