BTW: Hobby Lobby sells "automatic" connectors.

When you insert the wings, the servo clips are connected automatically.

These work best with low wing planes that have seperate removable wings, but they CAN be used with almost any plane.

My only misgiving about these, is that since they are affixed to the airframe, they will be subject to additional vibrations.

The upside is that as long as the wings are on, the connectors remain secure.
