Here are the four I have in flying condition. The Ultimate Biplane is a World Models ARF and the Yak profile is from AK Models. The Cap is from the GP kit and the Hots profile is scratch built. I'm also in the middle of an Ultra sSort .40+ build, I put my order in for an Ultra Sport .60 kit, I bought a Fun 51 kit today at the club swap meet and I am thinking about another ARF, possibly an Aeroworks Edge 540 or the GP Reactor. I'm sure I will find something else I want too; it never ends.
