The blue compound you see is Super-fil. There will be quite a bit of sanding involved to feather in the fuel tanks to create a nice smooth airfoil.This pic shows Super-fil at the seam that will need to be sanded.Here is the left side.The next few pictures show some aluminum strips that will be bonded and riveted after the fabric is put on. These strips are what holds the wing tips on. They needed to be fitted now but not finished until part way through fabric covering.
Still waiting for the Super-fil to cure, takes longer in this cold weather, so I started on the flapperons. The first chore is to rivet the trailing edge. The pop rivets supplied were a little long so I filed off the excess and polished them up with a dremel and aluminum polish. Much better.There are 18 rivets 8” apart on each trailing edge.This is the left end of the flapperons with the end cap clecoed in place.Here is the right flapperon finished.I got started on the left outboard cap. It will be balsa wood and finished in the same manner as the horizontal stabilizer and elevator. I only had enough balsa for one side, more ordered.
And Now For A Little Assembly
