1. Carefully sanded the backside of my "special" R flap fairing to make it as flat as I possibly could without compromising its appearance or structural strength. 2. Clecoed the R flap fairing in place. I think it will look OK (although *I* will be able to see its flaws every time I look at it. Oh well. 3. Riveted the L flap fairing onto the fuselage. It looks perfect.
