We folded the elev trim tab skin using the big fold brake we build and used on the elevator skins. Piece of cake.
The elevator trim tab skin's ends have the same silly sort of fold that I botched on the elevator skin, so I'm NOT taking that approach. With the tab's forward spar cleco'd in place, I crafted new ribs for each end of the tab. This was slow work, but hugely satisfying. More results in the next frame.
