Dynaflite DYFA2014 - Manual (Page 7)

Q 20. Joining the wing panels: Using the same
techniques outlined in steps 16 thru 19, prepare, fit
and glue the two wing panels together using the
die-cut 1/16" ply dihedral brace.
NOTE: The measurement for blocking up the wing
panels for this step is 3 ".Refer to the plans.
Q 21. Using .040" balsa, sheet the center of the
wing on top. Leave the lower bottom forward section
unsheeted where we will need to get to the W1 ribs
to install the hold down dowel.
Q 22. Glue the 3/16" x 1/2" balsa tip sheets
into place.
Q 23. Sand the wing so the airfoil looks like the
drawing on the plan labeled "typical rib section".
Shape the wing tips as shown on the plan.
U 6. Hinge the elevator to the stabilizer. Start by
cutting the hinges from the 2" x 9" strip of hinge
material to a size of 1/2" x 1". Snip off the corners
of the hinges for easier insertion.
Lt 7. Now use your knife to cut the slots into the
stab and elevator at the hinge locations shown on
the plans. CAUTION: Do this slowly. The wood is
thin. It is best to use many small cuts to get the
required depth. Test fit the hinges by joining both
parts. Make sure the bevel will allow the elevator to
move adequately up and down. Do not glue the
hinges in place until the model is covered.
Q 8. Sand the stab to the approximate airfoil shape
as shown in the cross section on the stab drawing.
Q 9. Glue the rudder front to the rudder.
U 10. Bevel the leading edge of the rudder
BUILD THE TAIL GROUP
Q 11. As before/ install the hinges to the fin and rudder.
U 1. Remove the die-cut stabilizer, elevator, fin and
rudder from their die-cut sheets. Refer to the die-cut
layout for identification.
Q 2. Start assembly by joining the stab front to the
stab. Using your sanding block, remove any die-cut
irregularities. When they mate to your satisfaction,
use CA to glue the two parts together. Sand the joint
to obtain a smooth surface.
Q 3. Tape the elevators to the stab.
U 4. Cut a piece of leftover spar material to fit into
the tie bar area between the elevators. When it fits
to your satisfaction glue it in place. Be careful not to
glue the elevator to the stabilizer!
Q 5. Remove the elevator from the stab and bevel
its LE as shown in the cross section on the plan. This
will allow for proper movement.
Q 12. Sand the fin and rudder to a nice thin
airfoil shape. Set these parts aside and move on to
the fuselage.
BUILD THE FUSELAGE
Q 1. Cover the fuselage section of the plans with wax
paper or plastic wrap. Start the fuselage by aligning a
die-cut 3/32" balsa doubler over the inside of a die-
cut 3/32" balsa fuse side. Align the doubler at the
front and top. When everything is aligned, glue the
doubler to the fuse side by applying thin CA around
the perimeter of the doubler. Be sure to make both a
left and a right side.
