Sand the edges until they are flush with the stab assembly.
Measure and cut a piece of 1/4" x 3/8" balsa, center and glue
to the leading edge. Sand until it is even with V7.
Glue the two V13 pieces together to make them 1/2" wide.
Glue this to the top of the stab as shown.
Sand V13 and even with the stab and round the leading
edges of the stab assembly.
Fit V11 to F18A so there is 1/16" edge for the sheeting to butt
against. You may need to sand the bottom of V11.
Align the stab assembly to the fuse by fitting the tab into the
slot in V11 and centering the trailing edge with the tail gear
wire. Glue in place
Fit the V14 tail sheeting to the vertical and horizontal stab.
Sand as necessary for a good fit. Glue in place with thick CA.
