So I framed up another one quickly with a 30" span and about a 22 degree wing rotation angle to see how it would glide, I was hoping it would not need significant trim with a moderate angle, however even with a lightweight frame, glide tests in the house showed it wanted to roll to the swept back wing pretty significantly, more than I felt comfortable trying to trim out under flight with just elevons. I chatted with Bob Parks and he confirmed this was what he expected. I was able to pull the wing off, re-dress the wing and tube and mount it as normal.
