6. Use a razor plane and/or a hobby knife followed
by a bar sander to shape the fin and rudder tip to
match the fin and rudder, but do not round the top
until the next step.
7. Now go ahead and round the tips of the fin and
rudder by sanding.
8. Remove the tape and separate the fin from the
rudder. Use a straightedge and a ballpoint pen to
mark lines on both sides of the rudder 1/4"[6mm]
back from the leading edge. Using the lines and the
centerline as a guide, shape the leading edge of the
rudder to a “V” shape to allow for control throw. Also
shape the front of the rudder tip as shown.
9. Test fit the rudder to the fin with the hinges.
Move the rudder back and forth to make sure it
moves freely. Make any adjustments necessary.
10. Use a putty knife or the included 1/16"[1.6mm]
die-cut plywood applicator to apply lightweight balsa
filler to partially fill the corrugations. Try to be
consistent and fill the corrugations about half-way as
shown in the sketch.
11. After the filler has dried, sand the surface of
the skins and down into the corrugations.
Set the fin and rudder aside while you build the stab.
BUILD THE HORIZONTAL STABILIZER (STAB)
Don’t forget, this is a one-piece, “flying”
stabilizer and has no elevators. Let’s start by
making the top and bottom stab skins…
1. Cut a 1-3/8"[35mm] strip from a 1/16"x 3"x
30"[1.6 x 75 x 760mm] balsa sheet to be used as the
trailing edge portion of one of the die-cut
1/16"[1.6mm] balsa stab skins. Use the remaining
1-5/8"[41mm] sheet to make the right and left
leading edge portions.
