I finished the kit inventory this am. I then began going through the plans, page by page. I noticed a few items that needed to be completed. The tie down on the undersurface of the wings needed to be tapped to handle a 3/8 inch tie down. Also the nutplates along the inboard rib both upper and lower skins needed to be placed. The upper skins were thick enough they needed to be countersunk. The lower skins could be dimpled. I used K1000-08 and K1100-08 nutplates depending on whether countersinking or dimpling was called for.
