RE: AIRTRONICS CUMIC PLUS ADVICE
I remember it, basically a Saggitta with a glass fuse, and I think a little longer wing. It was a little late to the party to be competitive in Unlimited class which had moved on to Windsongs and Magics, but a good airplane. The one my fiend flew had extended wings and wallowed some, so if there's an option to build two lengths go for the shorter wing.
