3. Place the servo into the servo tray. Center the
servo within the tray and drill 1,6mm pilot holes
through the block of wood for each of the four
mounting screws provided with the servo.
NOTE:
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. The
DECATHLON 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.

engine thrust washer should 110mm.
If your engine is equipped with a remote needle
valve, we suggest installing it into the engine at
this time.
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. Slide the pushrod housing through the hole in
the firewall, through the hole in the forward

5. Using a modeling knife, cut off the nylon pushrod
housing 26mm in front of the servo tray.
INSTALLING THE ENGINE
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.
Locate the long piece of wire used for the throttle
pushrod. One end of the wire has been
pre-bend in to a "Z" bend at the factory. This
"Z" bend should be inserted into the throttle
arm of the engine when the engine is fitted onto
the engine mount. Fit the engine to the engine
mount using the screws provided.
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.

INSTALLING THE SPINNER
INSTALLING THE wing strut
The wing strut was installed as the picutre below.
Install the spinner back-plate, propeller and
spinner cone. The spinner cone is held in place
using two 3mm x 20mm wood screws.
!
The propeller should not touch any part of the
spinner cone. If it dose, use a sharp modeling
knife and carefully trim away the spinner cone
where the propeller comes in contact with it.
INSTALLING THE RECEIVER AND BATTERY
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.

BALANCING
1. It is critical that your airplane be balanced
correctly. Improper balance will cause your
plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED 70mm
BACK FROM THE LEADING EDGE OF THE
WING, AT THE FUSELAGE. This location is
recommended for initial test flying and
trimming. There is a 10mm margin forward and
aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUEL TANK EMPTY.
82mm
525mm
105mm
42
2. Mount the wing to the fuselage. Using a couple
of pieces of masking tape, place them on the
top side of the wing 70mm back from the
leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your
fingers on the masking tape and carefully lift
the plane.
4. If the nose of the plane falls, the plane is nose
heavy. To correct this first move the battery
pack further back in the fuselage. If this is not
possible or does not correct it, stick small
amounts of lead weight on the fuselage under
the horizontal stabilizer. If the tail of the plane
falls, the plane is tail heavy. To correct this,
move the battery and receiver forward or if this
is not possible, stick weight into the firewall.
When balanced correctly, the airplane should
sit level or slightly nose down when you lift it
up with your fingers.

!
open and close the canopy
After you have balanced a plane on the C.G.
You should laterally balance it. Doing this will
help the airplane track straighter.
5. Turn the airplane upside down. Attach one loop
of heavy string to the engine crankshaft and
one to the tail wheel wire. With the wings level,
carefully lift the airplane by the string. This may
require two people to make it easier.
Nylon screw
6. If one side of the wing fall, that side is heavier
than the opposite. Add small amounts of lead
weight to the bottom side of the lighter wing
half's wing tip. Follow this procedure until the
wing stays level when you lift the airplane.
