Bryan and I spent a good chunk of time of Sunday peeling the plastic off of attachment angles for the ribs. Then we set about deburring all of them. I didn't count, but suffice it to say there were quite a few. All of the attach angles for the nose, center, back, aileron, and flap ribs got deburred.Next up was a bit of priming. We only had time and room for a small run so we took all of the aileron attach angles and cleaned, etched and primed. We called it a day after that.3 hours closer to having an airplane.
