What WB said about the trim might give the same appearance if a pilot were giving it extra effort.

From my limited observations and help rigging and derigging Schweizer single place gliders, I believe there is more butt-end structure where the 1-26's and 1-34's spar carry-through meets than on a 1-36, where if I recall correctly, the carry-throughs don't meet. Could be wrong though, it's been a long time. I was sensitive to this as a 1-36 near Colorado Springs returned from a flight with more dihedral than it departed with and another wound up in a BBQ pit in Boulder when a wing folded up. Not saying both weren't abused in flight, but the second ended up in a lengthy, ultimately unsuccessful, litigation with the operator's estate. Am also aware of at least a 1-26 where the wing folded up also, with better results. But never had access to a 1-26D or E to fly.

The 1-36 that got bent by the idiot in Boulder lives at our field and flies all the time. It is a testament to Ernie Schweizer's use of multiple redundant members in the spar. Nothing broke. It just yielded and stayed together to save the pilot's life. Irv Prue did the repair and told me he really liked the engineering.

More than one at Boulder I guess. The one I recall was a fatal, 1997. Maybe this link will work to download a PDF. I don't think this one was rebuilt. If it was, it's got another N number.

The one we had went to Penn State where was written off and rebuilt in Utah I think, where it may still be flying. It was unpopular at our club and was a hangar queen as a result. The last year the amortized cost of insurance per flight was $30, so it went away.
