Yes, it looks like the Stingray has the exact same wing with a little less dihedral. I think BalsaUSA might have simply flipped the fusealge upside down.

Funny everybody seems to like the Magnum/ASP 1.08 on this plane. I have the Magnum version and like it very much. I had it earmarked for my full-wing 4*60, which BTW is only a bit smaller than a clipped wing Thunderbug. Unfortunately, a friend of mine needs it more than I do for the GP PT-19 I'm putting together for him. In any case, if everybody is happy with the 1.08 on this plane, the TT 1.20 should be a blast.

I looked at the kit lumber more closely again. All the sticks are straight and of appropriate weight. The diecutting, while not as nice as laser-cutting, is very crisp and far superior to the die-crunch of the last couple of GP kits I had.

Russmall, sorry about your loss. Hmmm... the tail feather seems to be a weak point of this plane. Can you tell if the tail feathers just broke free of the fuselage, or did the open trusses just gave up? Now I'm thinking I might sheet over the built-up tail feathers and use flying wires.

bluther, what about yours? Did you have enough plane left to do a postmortem on how it failed?
