Out of the current crop of airplane kits out there, you may try the 1/2A Pathfinder, and the Pinto. There may be more but that is all that I can think of right now. A larger model to consider,if built light, is the SIG Akromaster. If you were to substitue 1/4" for the fuselage, and watch the wood everywhere else, I think the new .061 engine will fly that size airplane. That is on my "gotta try it" list also. Lots of smallish designs through the years also. If you can find a copy of the Stunt Model Bibliography that PAMPA put out, you can search that also. Keith Trostle did a neat 1/2A model called the Tercel that was in the magazines also. It's a rudderless design that he suggested to me one could really use a small vertical fin. I have the plans for that model also and it's on the "to do" list. Eric Rule at RSM offers a few kits also I think. Check out as many as you can research, and consider the ones that are the largest.
Type at you later,
