Thanks, Cosmo, Splatoman, the center wing section gets a bit wavy in the sun, but so does my 74" ESM Corsair. So far, they are both holding their own against the forces of nature and laws of physics. Ha. I keep them covered with a bedsheet or under the tables of the pitts area when not flying, at least in the really hottest part of Summer. Spring and Fall aren't too bad. But, like all warbirds, the next flight may be the last flight! ha. Sometimes they just go away.
Got another photo by Nancy Abby from the Big Bird meet. Little different angle of dangle on the wings.
