I think Balsa USA has the most to offer in this catagory. Any of their 1/4 scale planes will work and they also have an 80" Stringray that should do the job. I am looking at the 1/4 Fokker DVIII with a 80+" wing span. All of thier 1/4 scale planes say they will fly on the G-23 engine so a good running Ryobi should be more than enough power. They also have a Piper Cub with a 108" wing span that I know works wonderfully with an older 28cc Ryobi.

Try looking at www.balsausa.com
