I have the fuselage/ wing F3B fixed. The tank floor/ nose wheel well glassed in. I had to open up F2 to get my SS-16 fuel tank to fit. The elevators are trimed, thinned and sanded and are awaiting the tips to dry. I will have to mount my air tank in the fiberglass canopy. I will be making a large hole in the top block for access. The stab cutouts are done. Why you have to do it twice? It would be easier to have the stab capped and sanded and do it once.
