James, i once built a similar plane with only a 3" thick wing. I had a hard time getting up enough airspeed for the tail to start working. The plane was a littl tail heavy and all it wanted to do was hover. One of the first times I flew it, it headed straight for the outhouse and then hovered above it. I had a tough time getting it away from the outhouse. As you can guess, the plane got a name: the Outhouse Special.

I'll be interested to hear your flight report.
