Today I spent ages trying to get the right aileron twist correct, did I say a couple of days ago it would be relatively easy? I was wrong. Anyway, the flap & aileron line up within 2mm of each other & being faired with the fixed trailing edge reference points. I removed a spacer that I had placed under a lap joint on the left wing as it actually made the skin look worse and there was a lump under a skin overlap that was causing a bump on the right wing that I fixed. With all that done, the wings can go into the cradle again as they are finished except for some rivnuts to be installed for inspection panels & prep for paint. Just short of 500 hours spent building the wings must be a record for a Sling. The fuselage build begins on Monday, that shouldn't take too long. Clear prop!
