ank you for choosing the P-47D “Little Bunny” ARTF by SG MODELS . e
P-47D “Little Bunny” was designed with the intermediate/advanced sport yer in
mind. It is a semi scale airplane which is easy to y and quick to assemble. e air-
frame is conventionally built using balsa, plywood to make it stronger than the av-
erage ARTF, yet the design allows the aeroplane to be kept light. You will nd that
most of the work has been done for you already. e motor mount has been t-
ted and the hinges are pre-installed. Flying the P-47D “Little Bunny” is simply a joy.
is instruction manual is designed to help you build a great ying aeroplane. Please
read this manual throughly before starting assembly of your P-47D “Little Bunny” Use the

HINGING THE FLAP
Note : e control surfaces, including the ailer-
ons, elevators, and rudder, are prehinged with
hinges installed, but the hinges are not glued in
place. It is imperative that you properly adhere
the hinges in place per the steps that follow us-
ing a high-quality thin C/A glue.
- Carefully remove the ap from one of the
wing panels. Note the position of the hinges.
- Remove each hinge from the wing panel
and ap and place a T-pin in the center of
each hinge. Slide each hinge into the wing
panel until the T-pin is snug against the wing
panel. is will help ensure an equal amount
of hinge is on either side of the hinge line
when the ap is mounted to the aileron.

- Slide the wing panel on the ap until
there is only a slight gap. e hinge is
now centered on the wing panel and ap.
Remove the T-pins and snug the aileron
against the wing panel. A gap of 1/64” or
less should be maintained between the
wing panel and ap.

NOTE : e hinge is constructed of a spe-
cial material that allows the C/A to wick
or penetrate and distribute throughout
the hinge, securely bonding it to the wood
structure of the wing panel and ap.
- Deect the ap and completely satu-
rate each hinge with thin C/A glue. e
ailerons front surface should lightly con-
tact the wing during this procedure. Ide-
ally, when the hinges are glued in place,
a 1/64” gap or less will be maintained
throughout the lengh of the ap to the
wing panel hinge line.

- Turn the wing panel over and deect the
ap in the opposite direction from the oppo-
site side. Apply thin C/A glue to each hinge,
making sure that the C/A penetrates into
both the aileron and wing panel.
- Using C/A remover/debonder and a paper
towel, remove any excess C/A glue that may
have accumulated on the wing or in the ap
hinge area.
- Repeat this process with the other wing
panel, securely hinging the aileron in
place.
- Aer both ap 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 care-
fully applying medium pressure, trying to
separate the ap 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.

may need to adjust the size of the precut
opening in the mount. e notch in the
sides of the mount allow the servo lead to
pass through.
- Place the servo between the mounting
blocks and space it from the hatch. Use a
pencil to mark the mounting hole loca-
tions on the blocks.
- Use dental oss or heatshrunk tube to
secure the connection so they cannot be-
come unplugged.

OPTIONAL RETRACTABLE
LANDING GEAR
- Electric retractable landing gear is not
included in this kit, however it is a very
popular add-on as optional. If you want
to use retracts in your P-47D “Little Bun-
ny” , we recommend that you buy a good
set of electric retracts as the Himark
AM04 Main Gear shown as below. se
retract units will bolt right into the P-47D
“Little Bunny” inplace of the standard
ed gear.
- Use a hobby knife to trim the cover ing
from the retract opening. Make sure to
remove the covering support from the
opening at this time.

ous step.

wells into the wing. It may be necessary
to slightly trim the rib under the wheel
well so it rests ush against the wing. Use
canopy glue to secure the wheel well in
the wing.
