Fascinating. I knew the large prop and shorter gear leg reasons for the inverted gull wing of the Corsair but I had never heard of the wing attachment benefits.
A few years ago, but it seems like only yesterday, I had the opportunity to fly in some warbirds in NZ. The earlier comment about a Harvard reminds me of something I was told by one experienced warbird pilot. He said that anyone who could fly a Harvard well, would be easily able to fly most other warbirds. You just had to remember that you had more than 1000 extra horsepower!
