86'' Pattern Plane?
Not legal for F3A, but several companies over the last few years have come out with 50cc size pattern planes. A little larger plane that flies well. I know there was a discussion of a 50cc class a few years ago, but nothing ever materialized to my knowledge.

There is a company here in the states (name escapes me at the moment) that has at least one classic pattern planeenlarged to50cc size (wood kit). The wing area is small at 1200 but the effort may be worthwhile for some. I have the kit but plan on a modified, larger version to handle today's 50cc piped power
