Dynaflite DYFA1009 - Manual (Page 30)

Q 4. Align your straightedge with the marks on the
fuse top again, then lightly mark a 1" long centerline
on the fuse top in front of the LE of the stab.
ALIGN THE FIN
Q 1. Position the fin on the stab with the trailing
edge of the fin between the fuse sides.
Q 2. Cut the 3/16" x 3/16" x 6" balsa stick into
two 2-1/2" long pieces. Use your hobby knife to
carve them into triangle pieces (like the 1/4"
triangle stock used in the fuselage), then round the
ends. These are the fin braces.
Q 5. Align the fin with the centerline you marked on
the top of the fuselage, then pin the front of the fin to
the fuse sheeting with one small T-pin. Lightly trace
the outline of the fin on the fuse top and the outline
of the fin and triangle fin braces onto the stab, and
trace the outline of the fin braces onto the fin. These
lines will be guide lines for covering so you can glue
the fin and triangle pieces to bare balsa after you
cover them.
d 6. Cut the notch in the fin the same as you did on
the fuselage to allow the elevator to move up
and down.
Q 3. Temporarily place the fin braces on the fin and
the stab.
LJ 4. Use medium CA to glue a piece of leftover
1/16" balsa to the bottom of the fin in front of the
stab to fill the space.
PREPARE THE MODEL
Q 1. Remove the fin and stab from the fuselage.
Inspect the wing, fuselage, and tail surfaces for glue
joints that don't look strong and reinforce them with
thin or medium CA.
