Thanks Bob. Coming from "Mr. Stinger" that is most helpful. I am reluctant to admit that mine already weighs 41 oz (including 2 oz nose weight) and I don't see anywhere to put Buzz on a diet without major surgery. Still, I would hardly call its flight qualities mushy or sluggish; actually it was very quick and turns extremely tight, maybe 15 foot loops, way too tight for scored OTS competition. I really like the uniqueness of the model and will continue experimenting with it, maybe add another 2 oz and just accept it will be wiggly on the landing glide. Better still, build another one but change the construction/design of the fuse and tail, including use of RC motor mount (ie delete the ply formers and hardwood bearers entirely) and built up tail with lighter fuse sides and top. My local design team is already discussing the options!
