Another two day post here May 1st/2nd. After shooting both the lower wings I decided it was time to work on the upper wing. I pulled it off the wall and got right to work on the sanding it. It takes about 2 hrs per side to get it sanded down properly even with my orbital sander. You also have to hand sand a bunch of it and the easiest way not to damage the rib stitches is to just use the scotch brite around the rib stitches. It took me both days to complete the the sanding.
Time spent on the last two days 4 hours
Total Time spent. 1290 hours
