Dynaflite DYFA1009 - Manual (Page 35)

Q 5. Use a Trim Seal Tool or a MonoKote Iron
to seal the perimeter of the covering on the
reinforcements to the fin and stab.
Q 6. If necessary, cut 1/4" strips of covering and
use your Trim Seal Tool to iron the strips in the
"corners" where the bottom of the stab meets the
fuse and the fin meets the top of the fuse.
HINGE THE CONTROL
SURFACES
Make sure you join the elevator to the stab first,
then join the rudder to the fin.
CUT THE COVERING
AWAY FROM THE SLOT
the center of the hinge, then join the surfaces and
remove the pins.
Q 3. Confirm that the ends of the elevator align with
the ends of the stab, that the hinges are centered,
and there is a small gap between the stab and
elevator (just enough to see light). A small gap is
desirable so you do not inadvertently glue the
elevator to the stab.
Q 4. Carefully apply 4-6 drops of thin CA to both
sides of the hinges. Keep a cloth handy to wipe
away excess CA. If you spill a few drops of CA
on the covering, you can use CA Debonder
(GPMR6039) to remove it, or carefully peel it off
with a hobby knife after it fully cures.
Do not use accelerator on any of the hinges. Do not
glue the hinges with anything other than thin CA
and do not attempt to glue one half of the hinge at
a time with medium or thick CA. They will not be
secure and the controls could separate while the
model is flying.
Q 5. Let the CA fully cure, then carefully flex the
elevator several times to check the movement.
Q 6. Hinge the rudder the same way as the stab.
LJ 1. Use your hobby knife and a sharp #11 blade
to remove a small strip of covering from the hinge
slots to expose them.
TEMPORARY PIN
TO KEEP HINGE
0 2. Join the elevator to the stab with the hinges. If
the hinges will not stay centered, stick a pin through
Use 30-minute epoxy thinned with alcohol or
fuelproof model airplane paint to coat areas that
may be exposed to raw fuel or exhaust residue.
These areas include the firewall, inside the cowl
sides and bottom, the underside of the hatch, the
landing gear plate (if you did not cover it with
iron-on film), and inside the fuselage around the
wing saddle area.
