HINGING THE AILERON.
e control surfaces, including the ai-
lerons, elevators, and rudder, are pre-
hinged with hinges in stalled, but the
hinges are not glued in place. It is im-
perative that you properly adhere the
hinges in place per the steps that fol-
low using a high-quality thin C/A glue.
Note :
1) Carefully remove the aileron from one
of the wing panels. Note the position of the
hinges.
2) Remove each hinge from the wing panel
and aileron and place a T-pin in the center of
each hinge. Slide each hinge into the aileron
until the T-pin is snug against the aileron.
is will help ensure an equal amount of
hinge is on either side of the hinge line when
the aileron is mounted to the wing panel.
3) Slide the aileron on the wing panel until
there is only a slight gap. e hinge is nowcen-
tered on the wing panel and aileron. Remove
theT-pinsandsnugtheaileronagainstthewing
panel. A gap of 1/64” or less should be main-
tained between the wing panel and aileron.
.
.
To avoid scratching your new aer-
oplane we suggest that you cover
your workbench with an old tow-
el. Keep a couple of jars or bowls
handy to hold the small parts aer
you openthe bags. Please trial t
all parts. Make sure you have the
correct parts and that they t and
are aligned properly before gluing!
is will ensure proper assembly
as the RECREATION 148 is made
from natural materials and minor
adjustments may have to be made.
e paint and plastic parts used in
this kit are fuel proof. However,
they are not tolerant of many harsh
chemicals including the following:
paint thinner, cyano-acrylate glue
accelerator, cyanoacrylate glue de-
bonder and acetone. Do not let
these chemicals come in contact
with the colours on the covering
and the plastic parts.

HINGING THE ELEVATOR.
4) Deect the aileron and completely satu-
rate each hinge with thin C/A glue. e ailer-
ons front surface should lightly contact the
wing during this procedure. Ideally, when
the hinges are glued in place, a 1/64” gap or
less will be maintained throughout the lengh
of the aileron to the wing panel hinge line.
e hinge is constructed of a special
material that allows the C/A to wick
or penetrate and distribute through-
out the hinge, securely bonding it to
the wood structure of the wing panel
and aileron.
Note :
5) Turn the wing panel over and deect the
aileron in the opposite direction from the
opposite side. Apply thin C/A glue to each
hinge, making sure that the C/A pene-
trates into both the aileron and wing panel.
6) Using C/A remover/debonder and a pa-
per towel, remove any excess C/A glue that
may have accumulated on the wing or in the
aileron hinge area.
7) Repeat this process with the other wing
panel, securely hinging the aileron in place.
8) Aer both ailerons are securely hinged,
rmly grasp the wing panel and aileron to
make sure the hinges are securely glued and
cannot be pulled out. Do this by carefully ap-
plying medium pressure, trying to separate
the aileron from the wing panel. Use caution
not to crush the wing structure.
Work the aileron up and down sev-
eral times to “work in” the hinges
and check for proper movement.
Note :

1) Locate the item for this section of the
manual.
2) Carefully remove the elevator from one of
the horizontal stabilizer panels. Note the po-
sition of the hinges.

Glue the elevator hinges in place using the
same techniques used to hinge the ailerons.
HINGING THE RUDDER.
Glue the rudder hinges in place using the
same techniques used to hinge the ailerons.
3) Remove each hinge from the horizontal
stabilizer panel and elevator and place a Tpin
in the center of each hinge. Slide each hinge
into the elevator until the T- pin is snug
against the elevator. is will help ensure an
equal amount of hinge is on either side of the
hinge line when the elevator is mounted to
the horizontal stabilizer panel.

allow the servo lead to pass through.
4) Tape the servo lead to the wing to prevent
it from falling back into the wing.
5) Reinstall the servo into the servo mount
and secure the servo inplace using the wood
screws provided with you radio system.
2) Using a small weight (Weighted fuel pick-
up works well) and thread, feed the string
through the wing as indicated.
3) Attach servo lead to the aileron servo. At-
tach the string to the servo lead and carefully
thread it though the wing. Once you have
thread the lead throught the wing, remove

4) With the stabilizer held rmly in place,
use a pen and draw lines onto the stabilizer
where it and the fuselage sides meet. Do this
on both the right and le sides and top and
bottom of the stabilizer.
5) Remove the stabilizer. Using the lines you
just drew as a guide, carefully remove the
covering from between them using a mod-
eling knife.
Pen.
When cutting through the covering to re-
move it, cut with only enough pressure to only
cut through the covering itself. Cutting into
the balsa structure may weaken it.
6) Using a modeling knife, carefully remove
the covering that overlaps the stabilizer
mounting platform sides in the fuselage. Re-
move the covering from both the top and the
bottom of the platform sides.
Remove covering.
7) When you are sure that everything is
aligned correctly, mix up a generous amount
of 30 Minute Epoxy. Apply a thin layer to the
top and bottom of the stabilizer mounting
area and to the stabilizer mounting platform
sidesin the fuselage. Slide the stabilizer in
place and realign. Double check all of your
measurements once more before the epoxy
cures. Hold the stabilizer in place with T-
pins or masking tape and remove any excess
epoxy using a paper towel and rubbing al-
cohol.
8) Aer the epoxy has fully cured, remove
the masking tape or T-pins used to hold the
stabilizer in place. Carefully inspect the glue
joints. Use more epoxy to ll in any gaps that
may exist that were not lled previously and
clean up the excess using a paper towel and
rubbing alcohol.

2) Slide the vertical stabilizer into the slot in
the top of the fuselage. e rear edge of the
stabilizer should be ush with the rear edge
of the fuselage and the lower rudder hinge
should engage the precut hinge slot in the
lower fuselage. e bottom edge of the stabi-
lizer should also be rmly pushed against the
top of the horizontal stabilizer.
3) While holding the vertical stabilizer rm-
ly in place, use a pen and draw a line on each
side of the vertical stabilizer where it meets
the top of the fuselage.
4) Remove the stabilizer. Using a modeling
knife, remove the covering from below the
lines you drew.
When cutting through the covering to re-
move it, cut with only enough pressure to only
cut through the covering itself. Cutting into
