Dynaflite PT-19 - Manual (Page 26)

TEMPORARY PIN
TO KEEP HINGE
C. Join the elevator to the stab with the hinges. If
the hinges will not stay centered, insert a pin
through the center of the hinge, then join the
surfaces and remove the pins.
D. Confirm that the ends of the elevator align with
the ends of the stab, that the hinges are
centered and there is approximately a 1 /32"
gap between the TE of the stab and the LE of
the elevator. A small gap is desirable so you
do not inadvertently glue the elevator to the
stab with residual CA.
E. Carefully apply 6 drops of thin CA to each side
of all the hinges. Keep a tissue handy to wipe
away excess CA. If you spill a few drops of
CA on the MonoKote film you can use CA
Debonder (GPMR6039) to remove it. Or, wait
until the CA fully cures, then carefully lift it off
with a hobby knife blade.
F. Let the CA fully cure, then flex the elevator
several times to check the movement.
G. Use the same procedure to hinge the rudder
and ailerons.
19. Fit and install the landing gear.
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 control surfaces could separate
while the model is flying.
You may cover and finish your model now if you
desire. We prefer to install the radio before finishing so
we don't add any hanger rash to our finished model.
Our radio installation consisted of the following:
A. One S-148 size servo for each aileron. IMAA
rules may require higher torque servos.
B. One high torque servo for each elevator, with a
separate pushrod for each.
C. One quarter-scale servo for the rudder, with a
pull-pull system.
D. One S-148 size servo for the throttle.
E. We used a 1200 Mah battery pack to allow for
the additional servo drain.
While this is a large aircraft, it does not fly very fast.
We have found that the above installation has
worked very well.
This model will go into uncontrollable fits of sadness if
it isn't covered with fabric. Fortunately, Coverite 21st
Century prepainted fabric will eliminate this tendency
and looks great! You will need 15 feet of Cub Yellow
(COVQ0304), 15 feet of Mid Blue (COVQ0412),
2 feet of Light Red (COVQ0302), 2 feet of White
(COVQ0301) and 3 feet of Black (COVQ0310).
After you have finished covering, finish the hinge
installation as covered previously.
To install your windshields, cut and fit them to the
fuselage. Cut the covering where they will be glued
to the fuselage so that the windshields can be
adhered to the wood. Use tape or paint to detail the
panel lines.
Install your fuel system. We used a 16 oz. tank
(GPMQ4107) and a refueling valve (GPMQ4160).
Don't forget to fuelproof the engine and tank area.
