Aft Fins
Mark a line on the fuselage just about an inch above
and parallel to the top of the speed brake.
Shape the small horizontal fins to match the shape
of the fuselage. You may need to relieve the lower
edge a bit to get the fin to project horizontally. Use
the line as a reference, with the rear of the fin just
ahead of the horizontal stab leading edge.
CA small ply tabs inside the fins (see photo).
When dry, mark the position of the tabs on the line
you drew on the fuselage and carefully cut slots.
Test fit the fins. Make sure they are positioned
identically on both sides. Tape around the edges,
and on the surface of each fin for glue protection.
Aeropoxy the fins in place. Immediately remove
tape. Secure fins horizontally with tape until dry.
