Flap bracket alignment has changed. My kit #127 has them angled 90 degrees to the rear spar, but the new kits are 90 to the main spar Looking at multiple revisions of prints can cause confusion. Again, in hindsight, I may have completed skinning, then mounted ailerons, then positioned flap brackets to get perfect alignment. I'd bet newer kits have this a bit more dialed in as the angled outboard aileron bracket has been removed and now is mounted directly to the last rib.
