the first time I was dry fitting things, there was a huge gap in the back, but the LE was straight. understandable, as it's cut out of a big block, and no guarantee that was straight. so, I measured and cut...
looked pretty good, so I propped it up, but I must've biffed it somehow, thus the small gap. it looks tight from the spar back, but the spar fwd it a little wonkey. a few quick checks (I noticed it this morning while getting ready for work), and it looks straight and such, just this annoying gap. I also tried to flex the wing, I couldn't make it spread.
I think a 2" wide strip and some epoxy may be in my future....
