We made some tweaks around the left butt rib because it didn't line up cleanly with the root web, causing slight interference whenever we would open or close the wing. To fix this, we sanded back the front edge of the butt rib slightly (area adjacent to the front spar), and also sanded a sliver of material on both the butt ribcap and root ribcap so that that we had an even spacing between the two. After making the mods, the issue with interference was fixed.

We also added four nutplates to one of the fabric plates on the right wing which will allow us to (later) easily add a fairing at the exit point where the cable runs to the rudder.

Lastly, we installed eight control pulleys inside the fuselage. These pulleys are for the cables that will ultimately run from the controls to the rudder and ailerons. We either used up all the washers we had for AN4 bolts, or misplaced them, so will have to order a bunch more. Hours 2.0
