Flaps and Ailerons

The Flaps and ailerons are built in one piece per side in order to make setting the wash-out on each a whole lot easier. I’ve elected to taper the spar to fit the rib contour before gluing the ribs on. I hope this will make the float sanding go a whole lot easier than on previous constructions.

Starting a flap/aileron

The ribs are cut from 8mm Spruce on a bandsaw ( which I had been putting off buying but finally had to ) then sanded. The construction is carried out with the hinges fitted the to the spar.

Framework completed

Just starting to fit the trailing edge ribs to the spar. Each spacer under the rib is a different thickness to achieve wash-out.

Starting to skin.

Basic frame construction complete ready for float sanding. My pre-shaping of the spar is now paying off.

I’ve now finished both sides and I’m now onto the wings !!
