Dynaflite DYFA1009 - Manual (Page 8)

Place your building board on top of your flat
building table. Unroll the plan sheet, then reroll it the
opposite way so it will lay flat. Position the rudder
and fin drawing over your flat building board. You
may separate the wing portion from the plan, or fold
the plan in half to make it easier to work with. Cover
the rudder and fin drawing with wax paper so the
glue will not stick to the plan.
BUILD THE RUDDER
position with medium CA. Where possible, cut the
sticks slightly too long so you can trim them to exact
length as you complete the assembly. You can cut the
tip and bottom pieces too long, and trim them after
you remove the rudder from the plan.
L-l 3. Make the rudder horn mount plate from the
1/8" x 1/4" balsa stick, then glue it in position with
medium CA. Accurately cut the "braces" from a
1/8" x 1/8" x 36" balsa stick, then place them in
the frame and glue them in position with thin CA.
LJ 1. Accurately cut the three vertical rudder pieces
including the leading edge (LE), rudder post (the
middle part) and the trailing edge (TE) from a 1 /8"
x 1/4" x 36" balsa stick. Then pin them over their
locations on the plan with small T-pins. Many
modelers find that they can more accurately cut
small balsa sticks with a single-edge razor blade
instead of a hobby knife.
LJ 2. Cut the five horizontal rudder pieces from the
same 1/8" x 1/4" balsa stick, then glue them in
LJ 4. Remove the T-pins, then lift the rudder from
your building board and peel off the wax paper.
Reinforce glue joints that don't look strong with
medium CA, then set the rudder aside and continue
with the rest of the tail pieces.
