It turns out that having stability in the wing joints is hard and whats harder is to thread the servo control cables through the wings.
So to this end I have put in perminate wiring .
The socket is a 8pin din plug through which I run the 2 servos and a usb connection for the on-board camera in the wing.
Then when I go to connect the wing up all there is a plug to plug in, the carbon fiber rod (at rear) to lock in and then screw up the top and bottom plates in the middle. Ready to fly.
