More rib fitting today. I was able to fit four of the five flap ribs mated to the upper and lower wing skins today. In total, I've now got eleven ribs completely fitted. That's almost half of the total twenty-three ribs needed. I'm still pretty well stymied until more epoxy arrives, though. I've just got a few more ribs I can really fit well until I'm able to complete the main spar pad.
