RE: Good Second Plane?
Take a look at Sig's Rascal 40 ARF. It has a 72" wingspan, is a high wing tail-dragger, wheel pants and a neat retro- 30's look about it. It flies great and even does some mild aerobatics. The wing is 2-piece, so it transports easily, and should fly fine with a .46 2-stroke. The only concern (?) I might have is that it requires an inverted engine installation, because the engine mount is built into it. I say concern only because I don't know how much you might want to mess with the inverted engine. I have a Rascal 40, love the way it flies; I have a Saito .56 mounted inverted in mine and I have no problems at all with idle, starting, etc(all the things you hear about inverted mounting that are supposed to be "bad").
The trainer I have and still fly a lot ('cause it's fun to thrash) is a Superstar, and I think the Rascal flies better and more easily. I crashed mine a couple of times over the last year, wound up re-covering it (the crashes were my own stupidity), and I am building a set of floats for it now.
The last picture I included just 'cause it was next to the Rascal in my files. Chuck and me, 1988, talkin' about airplanes over a brewski. (Brooks AFB O.C., San Antonio
