Yeah at first I wanted to make it so when you plugged in the wing, the connection was made automatically, but in a foam construction I don't think this would hold up well over time. So I decided that since that was out of the picture, that I would take a very simple approach and just minimize the connection process as best I could.
Please post pics of your approach when you can.
I went through the same thought process... "How can I make this plug in automatically...?" In the end, I realized that the multiplex connector is far too tight. It'd eventually wear out the foam supporting it. Perhaps some day I'll add plywood reinforcement and give it a go, but this is working great already. ~3-4 minutes out of the trunk of the car, and I'm ready to fly.
I also added the Morgan Mill servo fairings during this session. I had tweaked my right aileron servo horn during my maiden, and wanted no more of that! The fairings are perfect. I recommend them to all RP pilots.
