After checking the spars still mate ok, it was time to re-install the wings and hope my experiment with the first set of attach angles so I won't have to do any more drilling. I had my friend Austin come over to give me a hand installing them again. And guess what, they fit perfectly, I could not be more pleased with the result, I must say I expected to have to need at least one of the extra angles I made but no, everything matches and lines up. The pins fit, very very snug into the holes, a really good result indeed, again I am very happy. I can sleep again! (I've lost quite a bit of sleep over this issue) After we were done I put the wings in the new stand I made yesterday, looks good and works well.
