Scratch build
AV8TOR,
There are many plans that would lend themselves to your engine with a little modification. The one I personally like the best is the Milennium that was published in a Traplett (British) magazine a year or so ago. It has a picture of the plane on the front of the magazine. Scaled for a .40 but could be enlarged.
I am flying a UCD3D and love it. OS 91/4S. Still trying to learn all the new possibilities. I love to build too however this plane makes it hardly seem worth the effort or expense.
