Prboz:
I remember an article in an English mag and I think it was a Hellcat (correct me if i'm wrong) that would lower the wings from the parked position (Wings up / Folded) before takeoff and raise them again after landing.
Earl Aune (he lives in Oregon) did this to a Corsair (not sure if this is the same one you are talking about, but it sure is cool). As he is taxing out to the runway he lowers the wings. The folding wing plans are available from Bob Holman.
