Bob, I bet your Beretta has got a higher take-off speed as the one in the picture I posted...
The model is basically a modified Club 20 pylon racing plane without the minimum sizes dictated by the racing rules. The wing is thinner and the fuse is designed to accomodate the pipe on a rear exhaust engine. Fuse can be had in glass or kevlar. Wings are a foam glass balsa laminate. Tail feathers are laminated also.
So wingspan is about 30", wing area is about 300 sq.in.
The exact size actually aren't mentioned on the site, but since it's a modified Club 20 plane they shouldn't be too far off...

It is an annoying site!
That Rossi engine is supposed to produce 2.3 hp at 34K rpm...should make for an interesting sound...
