You know, I got thinking about this and remembered that a GP Cap 231EX ARF (.46 size) I had did the same thing. After checking the wing, I noticed that the right wing half had +2deg of incidence. After twisting and reshrinking over a week, I got it to 0deg like the other side. It flew MUCH better after that. Still snapped if you weren't carefull though (just the nature of this beast).
