Before starting construc,tion of your model, study the plan
and construction procedure carefully so that you'will frave
a complete understanding of the step-by-step method of
building th.is airplane. Guillow engineeiing has provided
yoq wjtf the most_up-to-date methbd for bultdirig a real
scale flying model but only careful artenrion to det-ail will
insure the success of your efforts.
Mosr pri-ze winning scale models are the result of patience
and careful workmanship. You too can achieve su-ccess bv
following^the,_-e.:tgpie. o^f 9ha11pjon model builders - by
working SLOVLY and CAREFULLY at all times.
The frame photographs sh_own on this instruction sheet are
actual picrures of the model you are about to build. The
line drawings. under each photo show the method of frami
constructlon but are not actual illustrations of the model
you are making. In other words, refer to the line drawings
for construction p-rocedure -_refer to the photos fo" co-rr-

This is not the model you qre building but the method
of construction is exoctly fhe some in most respects.

The wings of models with scale dihedral should be cracked at ribs shown
on fronf view of wing plan. Raise wing rips to height shown and lhen

on plan for increased dihedral as an aid to better lateral stabilify in flying.
When dry, remove wing frames from plan. Carve and sandpaper leading

BUITDING TAIL SURFACES AND OTHER FRAMES
1. Pin to plan, and cemenr respectively to each other, all
rudder parts "C". Cut 1r16" sq. members to size and
cement in position,
2, tsuild stabilizer frame in a similar manner using parrs
"D" and 1/16" sq. members.
3. Remove frames fr5m plan and sandpaper lightly, round-
ing all edges.
4. Pin landing gear parts strut layout after cement-
rng pleces together,
5. For models with N or V cabane struts, assemble parts
"J" over layout. For models with N or V wing struts,
assemble parts "I(" over layouf.
The directions ihel follow indicate lhe order in which the model frames are covered and assembled. For
more detailed information on how to cover and finish a balsa flying model, consult fhe folder'1/aluable
Modeling Hints" included in this kii. The illustrations in the folder DO NOT represent ihe model you are
building but ihe work procedures are quite similar in most respecls.
COVERING
rVhen attaching the tissue covering to rhe frames, it is best
to use thinned out clear dope as an adhesive instead of
cement,or full strength dope, Mix thinner and dope about
5O-5O for proper. consistency. Only apply dope to outside
edges of areas being covered - do not apply dope to frame
work within area covered by section of rissue.
FUSELAGE: F'irst cover any flat surfaces such as sides and
bottom of frame. Cover curved areas of fuselage in sepa-
rate sections - vertically berween formers. Div fit tisiue
over curved sections to see how much of an aiea can be
covered with one piece of tissue without wrinkling, Cut
tissue siightly larger riran area ro be covered then trim off
excess after attaching to frame.
WINGS: Cover bottom of .wings with single pieces of
tissue, Cover top of wings between center section and tip
THE FRAMES
ribs with one piece of tissue. Cover center sections and
tips with separate pieces of tissue.
TAIL SURFACES: Cover both sides of rudder and top and
bottom of stabilizer with single pieces of tissue.
DOPING THE COVERED PARTS: After covering is
completed and all excess tissue is rimmed ofl. spray tiisue
with water from an atomizer and ler -dry untii covering
becomes smooth and raut, _Ior best flying performance]
the model should be kept_light and ir isluggested thai
only one coat of clea-r dope be applied to the srirTaces. (If
model is to be used for display only, it can be given several
coats.of clear dope then finished up with col-ored dope.)
Lightly sandpape:remaining balsa parrs and apply one ioai
of dope to all surfaces.
ASSEMBTING
Vith a sharp razor, remove tissue from around notches
in wing ribs that receive the wing and cabane struts.
Also remove tissue from notches in parts "L" of fuse-
lage.

Vith a sharp razor, remove tissue frr:m around notches
in wing ribs that receive the wing and cabane struts,
Also remove tissue from notches in parts "L" of fuse-
Iage.
Cement bottom wing to the fuselage. NOTE: Some
models have short stringers between the formers at
the bottom wing center section. Insert these stringers
at this time; cover section with tissue and dope.
Cement stabilizer and rudder to fuselage. Alien care-
fully before cement dries hard.
Cement cabane struts into prepared notches in fuselage.
Cement wing struts in notches in bottom wing.
Cernent top wing to all struts - line up carefully before
cement dries hard.
Cement landing gear into notches in fuselage and bot-
tom ot w1ng.
Cenent fixed sub-wing panel between bottom of land-
ing gear struts. Cement tail skid "K" in place.
Cut wheel axle to iength then force through right and
left landing gear struts beneath the sub-wing - cemenr
bottom of stabilizer with single pieces of tissue.
DOPING THE COVERED PARTS: After covering is
completed and all excess tissue is rrimmed off, spray tiisue
with water from an atoinizer and ler _dry untii.covering
becomes smooth and taut. For best flying performance,
the model should be kept light and ir is sueeested thai
only one coat of clear dope be applied to rhe sur?aces. (If
model is ro be used for display only, it can be given several
coats_of cle_ar dcpe then finished up with colored dope.)
Lightly sandpaper_ remaining balsa parts and apply one coat
of dope to all surfaces.

ADJUSTING AND FTYING
1. Check wings for possible warps. If warped, correct by
holding the warped section over steam from a boiling
kettle and twisting gently in the opposite direction until
wing is straightened - be careful and don't get scalded!
2. Test glide model over grassy area by gently thrusting
model forward from shoulder height. Adlust model foi
level flight by gently bending stabilizer either up or down
to compensate for a dive or climbing stall. ("up"
stabilizer for dive - "down" stabilizer for stall). If.
COMPTETING
Use black thread to simulate rigging wires. Refer to
small three view plan for location of all wires.
Full scale details of guns, motors, non-fying scale prop,
etc., are furnished on plan. No material is furnished
in the kit for these parts but they can be made from
pieces of scrap balsa or similar material. Only add
THE MODET
solidly in place.
10. Slip wheels on axles and bend up ends with a pair of
needle nose pliers.
11. Cut celluloid windbreaker to shape and cement in
position in front of cockpit. (Pattern furnished on
plan).
12. At this time, balance model at point shown on plan by
placing softened clay inside the front and bottom of
fuselage behind the front former. Press firmly in
place -so that it will not become dislodged during
flights.
13. Trim plastic nose cowl to shape and slip over nose of
fuselage - bead all around edges with cement.
14. Assemble propeller, prop hook, head and nose bearing
as shown on plan. Install rubber motor as follows:
insert one end in fuselage and fasten in place by sliding
rear motor mount (cut frorn excess axle wire) through
loop and "L" parts. Attach other end of rubber loop
over prop hook and slip propeller unit into hole in
plastic nose cowl,
THE MODEL
these parts if an exhibition model is desired - their
extra weight will cut down the flight endurance of a
flying model.
3. Finally add the insignia as per instructions on reverse
side of decal.

model veers right or left, adjust for straight glide by
bending rudder in opposite direction of curved {light.
3. $/ind propeller 1oo turns (clockwise when facing nose
of model) and gently thrust into prevailing wind. If
model climbs too rapidly or goes into a stall, correct
flight by bending rudder slightly to the right to give a
climbing right-turn. Longer flights can be made after
initial rests by winding propeller motor up to 2oo
