Ed has a good point there. I never gave that any thought before, but I also think taking the dihedral out of a Telemaster would likely take away some of the "nicenest" (spelling) of its flying characteristics. There were times when I just liked trimming it out to fly steady circles by itself and I could take my hands off the sticks for a time. That would be hard to do without dihedral. I love to touch and go this plane on one wheel and running the length of the runway that way. The dihedral I think makes that a lot easier plus the extra clearance helps. Also, when carring gliders on the glider launcher, I think the dihedral would give it extra stability. I does get a little squirrely with another plane attached to it. Being a flat bottom wing, it seems like little gain in aerobatics making it straight for this plane. It may fly inverted a little better without wanting to roll out, but it still needs more power to do that with the flat bottom. An interesting thought; do you think it would feel more like a Piper Cub with a straight wing? I guess it all depends on what feel you want in its handling characteristics.
