Prepare the 3 mm balsa tail surfaces, but wait
with glueing those to the fuselage until after
the iron-on covering has been applied. Glue
the two pieces of the tail fin together, sand
smooth and round the front and top edges.
The rear edge shall remain squared since this
is where the rudder hinges.
Finally, add a strip 3 mm balsa to
the inside of the fuselage sides at
the wing rest, and bevel these to the
dihedral angle of the wing to give it
a larger supporting surface. This
does not add any strength or rigidity,
but it avoids indenting the wing
bottom surface.
Glue two 50x8x2 mm pine pieces to the fuselage bottom,
on either side of the removable landing gear. To adjust
their position, temporarily slide the L/G legs into their
mounting holes with the wires against each other, apply
glue to the pine parts, position them close to the L/G wires
and slide these against the wires while the glue is still wet.
Remove the legs carefully without moving the pine parts
and remove any excess glue.
Glue the 3 mm ply tail skid directly to its ply support after
making a slot in the balsa planking that covers it (no
picture, see drawing).
Sand the stabiliser smooth and round all edges except the rear edge, the elevator hinges
here.
Bevel the front edges of the rudder and elevator parts at an angle of approx 40 degrees
to allow deflection to either side (no picture, see drawing).
