Mike, this looks a lot like the Midwest Aerobat.. high wing aerobatic aircraft. Frank Granelli, from Sport Aviator, did a review on the Midwest Aerobat a couple years ago and based on that, I bought one and really enjoyed flying it. I ended up crunching it in, broke the horizontal stab, which was bolted in place with nylon 16-10 bolts, if I recall and had a rubber band mounted wing. I glued in the horizontal stab but it would never stay on for some reason. But, it was a great flyer while it lasted..
From the pictures, this one looks like it has a bolt down wing and very little dihedral.. is that a correct observation? Also, is it a flat bottom wing or a semi symetrical wing config?
Maybe this can restore my loss of confidence in Goldberg (based on the Tiger 120 fiasco several of us have experienced - over a pound of lead weights in the nose to make the CG!! )
Dick.
