Folding Corsair wings
Earl Aunn who is one of the Scale Master guys in Oregon did this on an F4U that he flew on the scale circuit a few years back. It was an absolutely beautiful model and left the pits with the wings folded. As he taxied the plane out the wings came down and the canopy closed. It even had a working Radar screen on the instrument panel. Unbelievable detail. It was done up in the F4u-5 night fighter paint scheme. It won best of show honors at the Northwest Hobby Expo and it was well deserved. Find Scalemasters website and you should be able to contact Earl as he is very active in that organization.
