Ok I like then ideasolution: 10 sliding parts at each wing... "mylar sheets! Eg, X-ray film. Thats thin , 10 parts will be 3.5mm , but a bit stiff anyway, at least when each part would have a former, and an edge under next one at 50mm wide., and slides nicely on carbonfiber tubes in front of each wing
Then awaiting return info from a office machine service guy on internal content to fit for retract/push out parts
Retract controller for dc motors is already fixed.
