I heard great things about the Kavalier as well. So much so that I went out and built one. I managed to get it up for a short flight to trim it out. The second time going up it climbed out nice and easy with a slight roll. When I was ready to level it out I realized I no longer had control of it and it slowly roled over on its back and took a nose dive into the ground. The fustrating thing about it is to this day I don't know why it crashed. One day I might try and build another one.

Enjoy,

Brett
