GEEBEE. Instruction Manual

INTRODUCTION.
Thank you for choosing the GEEBEE ARTF by SG MODELS . The GEEBEE was
designed with the intermediate/advanced sport scale in mind. It is a semi scale airplane which is
easy to fly and quick to assemble. The airframe is conventionally built using balsa, plywood to make
it stronger than the average ARTF , yet the design allows the aeroplane to be kept light. You will find
that most of the work has been done for you already. The motor mount has been fitted and the hinges
are pre-installed . Flying the GEEBEE is simply a joy.
This instruction manual is designed to help you build a great flying aeroplane. Please read this
manual thoroughly before starting assembly of your GEEBEE. Use the parts listing below to identify
all parts.
WARNING.
Please be aware that this aeroplane is not a toy and if assembled or used incorrectly it
is capable of causing injury to people or property. WHEN YOU FLY THIS AEROPLANE YOU
ASSUME ALL RISK & RESPONSIBILITY.
If you are inexperienced with basic R/C flight we strongly recommend you contact your R/C
supplier and join your local R/C Model Flying Club. R/C Model Flying Clubs offer a variety of training
procedures designed to help the new pilot on his way to successful R/C flight. They will also be able
to advise on any insurance and safety regulations that may apply.

1) Carefully remove the aileron from one
of the wing panels. Note the position of the
hinges.
2)Removeeach hingefromthewing panel
and aileron 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. This will help ensure an equal amount
ofhingeis oneithersideof thehingeline when
the aileron is mounted to the aileron.
3) Slide the wing panel on the aileron until
there is only a slight gap. The hinge is now
centered on the wing panel and aileron.
Remove the T-pins and snug the aileron
against the wing panel.A gap of 1/64” or less
shouldbe maintainedbetween thewingpanel
andaileron.
The control surfaces, including the
ailerons, elevators, and rudder, are
prehinged with hinges installed, but the
hinges are not glued in place. It is
imperativethat youproperly adherethe
hingesin placeper thesteps thatfollow
using a high-quality thin C/A glue.
Note:
4)Deflect the aileron and completely
saturate each hinge with thin C/A glue. The
aileronsfrontsurface shouldlightlycontactthe
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.
Note: The hinge is constructed of a special
material that allows the C/A to wick or
penetrateanddistribute throughoutthe
hinge, securely bonding it to the wood
structureof thewing panel andaileron.
To avoid scratching your new aero-
plane we suggest that you cover your work-
benchwith anold towel.Keep acouple of jars

aileron in the opposite direction from the
opposite side. Apply thin C/A glue to each
hinge,makingsurethattheC/Apenetratesinto
both the aileron and wing panel.

TURNBUCKLE INSTALLATION.
8)Afterbothailerons are securely hinged,
firmly grasp the wing panel and aileron to
make sure the hinges are securely glued and
cannot be pulled out. Do this by carefully
applying medium pressure, trying to separate
the aileron from the wing panel. Use caution
not to crush the wing structure.
7) Repeat this process with the other wing
panel, securely hinging the aileron in place.
HINGING THE RUDDER.
Glue the elevator hinges in place using the
same techniques used to hinge the ailerons.
Glue the rudder hinges in place using the
same techniques used to hinge the ailerons.
Work the aileron up and down several
times to “work in” the hinges and check
for proper movement.

tothe weightedfuel pickup and theother end
to the nylon pick up tube.(The silicon tube is
not included).
3) Carefully bend the second nylon tube
up at a 45º angle. This tube is the vent tube.
1) Using a modeling knife, carefully cut
off the rear portion of one of the 3 nylon tubes
leaving 1/2” protruding from the rear of the
stopper. This will be the fuel pick up tube.

4) Test fit the stopper assembly into the
tank. It may be necessary to remove some of
the flashing around the tank opening using a
modeling knife. If flashing is present, make
sure none falls into the tank.
5) With the stopper assembly in place,
the weighted pick-up should rest away from
therear of thetank and movefreely inside the
tank. The top of the vent tube should rest just
below the top of the tank. It should not touch
the top of the tank.
Important: When the stopper assembly is in-
stalled in the tank, the top of the vent tube
should rest just below the top surface of the
tank. It should not touch the top of the tank.
Carefully use a lighter or heat gun to
permenently set the angle of the vent tube.
6) When satisfied with the alignment of
the stopper assembly tighten the 3 x 20mm
machine screw until the rubber stopper ex-
pands and seals the tank opening. Do not
overtighten the assembly as this could cause
the tank to split.
FUEL TANK INSTALLATION.
You should mark which tube is the vent
and which is the fuel pickup when you
attach fuel tubing to the tubes in the stopper.
Once the tank is installed inside the fuselage,
it may be difficult to determine which is which.
