I am currently building my Ultra Flash. I was a bit disappointed about the one-piece wing. I hate transporting one-piece wings. They always seem to be in the way in the trailer or get bumped. But, the UF does come with wing protection covers and it is a well proven plane that flies well. So, .. I bit on it. But, flipping over a plane to put on its wing and gear is a PITA. I am hoping I get used to it.
