This instruction manual is designed to help you build a great flying aeroplane. Please read this
manual thoroughly before starting assembly of your TROJAN. 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.

To avoid scratching your new airplane, do not
unwrap the pieces until they are needed for
assembly. Cover your workbench with an old
towel or brown paper , both to protect the
aircraft and to protect the table. Keep a couple
of jars or bowls handy to hold the small parts
after you open the bag.
Please trial fit all the parts. Make sure you have
the correct parts and that they fit and are
aligned properly before gluing! This will assure
proper assembly. TROJAN ARF is hand made
from natural materials, every plane is unique
and minor adjustments may have to be made.
However, you should find the fit superior and
assembly simple.
The painted and plastic parts used in this kit
are fuel proof. However, they are not tolerant
of many harsh chemicals including the
following: paint thinner, C/A glue accelerator,
C/A glue debonder and acetone. Do not let
these chemicals come in contact with the
colors on the covering and the plastic parts.

3. Plug the aileron servo into the receiver
and center the servo. Install the servo arm onto
the servo. The servo arm should be
perpendicular to the servo and point toward
the middle of the wing.
4. Locate one nylon servo arm, and using
wire cutters,remove all but one of the arms.
Using a 2mm drill bit, enlarge the third hole
out from the center of the arm to accommodate
the aileron pushrod wire.
5. Using pliers, carefully make a 90 degree
bend down at the mark made. Cut off the
excess wire, leaving about 4mm beyond the
bend.
6. Insert the 90 degree bend down through
the hole in the servo arm. Install one nylon
snap keeper over the wire to secure it to the
arm. Install the servo arm retaining screw and
remove the masking tape from the aileron.

the antenna to exit.

1) Plug the servo leads and the switch
lead into the receiver. You may want to plug
an aileron extension into the receiver to make
plugging in the aileron servo lead easier
when you are installing the wing . Plug the
battery pack lead into the switch.

When the stopper assembly is installed
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.
2. Using a modeling knife, cut one length of
silicon fuel line (the length of silicon fuel line is
calculated by how the weighted clunk should
rest about 8mm away from the rear of the tank
and move freely inside the tank). Connect one
end of the line to the weighted clunk and the
other end to the nylon pick up tube in the
stopper.
3. Carefully bend the second nylon tube up
at a 45 degree angle (using a cigarette lighter).
This tube will be the vent tube to the muffler.
4. Carefully bend the third nylon tube down
at a 45 degree angle (using a cigarette lighter).
This tube will be vent tube to the fueling valve.
INSTALLING THE STOPPER ASSEMBLY
FUEL TANK.
1. The stopper has been pre-assembled at
the factory.
Blow through one of the lines to ensure
the fuel lines have not become kinked inside
the fuel t ank compartment. Air should flow
through easily.
9. To secure the fuel tank in place, apply a
bead of silicon sealer to the forward area of
the tank, where it exits the fuselage behind the
engine mounting box and to the rear of the tank
at the forward bulkhead.
8. Feed three lines through the fuel tank
compartment and through the pre-drilled hole
in the firewall. Pull the lines out from behind
the engine, while guiding the fuel tank into
place. Push the fuel tank as far forward as
possible, the front of the tank should just about
touch the back of the firewall.
.
7. Using a modeling knife, cut 3 lengths of
fuel line 150mm long. Connect 2 lines to the 2
vent tubes and 1 line to the fuel pickup tube in
the stopper.
5. 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 of it falls into the tank.
6. When satisfied with the alignment of the
stopper assembly tighten the 3mm x 20mm
machine screw until the rubber stopper
expands and seals the tank opening. Do not
over tighten the assembly as this could cause
the tank to split.

onto the engine and make the cutout in the
cowl for muffler clearance. Connect the fuel
and pressure lines to the carburetor , muffler
and fuel filler valve.
3. Slide the cowl back over the engine
and secure it in place using four wood screws.

When cutting through the covering to
remove it, cut with only enough pressure
to only cut through the covering it’s self.
Cutting into the balsa structure may
weaken it. This could lead to possible
failure during flight

you just drew as a guide, carefully remove the
covering from between them using a modeling
knife.

5. 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 sides
in the fuselage. Slide the stabilizer in place and
re-align. Double check all of your
measurements one more time before the
epoxy cures. Hold the stabilizer in place with
T-pins or masking t ape and remove any ex-
cess epoxy using a paper tower and rubbing
alcolhol.
