INTRODUCTION.
Instruction Manual.
ank you for choosing the Westland Lysander ARTF by SEAGULL MODELS COMPANY
LTD,. e Westland Lysander 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 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 nd that most of the work has been done
for you already. e motor mount has been tted and the hinges are pre-installed. Flying the
Westland Lysander 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 Westland Lysander . Use the parts listing
below to indentify all parts.
WARNING.
Please be awere that this aeroplane is not a toy and if assembley or used incorrectly it is
capable of causing injury to people or property. WHEN YOU FLY THIS AEROPLANE YOU
ASSUME ALL RISK & REPONSIBILITY.
If you are inexperienced with basic R/C ight we strongly recommend you contact your R/C
supplier and join your local R/C model Flying Club. R/C Model Flying Clubs oer a variety
of training procedures designed to help the new pilot on his way to successful R/C ight.
ey will also be able to advise on any insurance and safety regulations that may apply.

ASSEMBLY.
1) Using a modeling knife, carefully cut
o the rear portion of one of the 3 nylon
tubes leaving 1/2” protruding from the
rear of the stopper. is will be the fuel
pick up tube.
2) Using a modeling knife, cut one length
of silicon fuel line. Connect one end of
the line to the weighted fuel pick up and
the other end to the nylon pick up tube.

Instruction Manual.
5) With the stopper assembly in place, the
weighted pick-up should rest away from the
rear of the tank and move freely inside the
tank. e top of the vent tube should rest just
below the top of the tank. It should not touch
the top of the tank.
6) When satised with the alignment of the
stopper assembly tighten the 3 x 20mm machine screw until the rubber stopper expands
and seals the tank opening. Do not overtighten the assembly as this could cause the
tank to split.

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 dicult to determine which is which.
7) Slide the fuel tank into the fuselage. Guide
the lines from the tank through the hole in
the rewall.
8) Use plywood template to hold in place the
fuel tank with C/A glue to secure the fuel
tank inside the fuselage.

4) Test t the stopper assembly into the tank.
It may be necessary to remove some of the
ashing around the tank opening using a
modeling knife. If ashing is present, make
sure none falls into the tank.

Please see these below pictures.
Reinstall the servo horn by sliding the
connector over the pushrod wire. Center
the throttle stick and trim and install the
servo horn perpendicular to the servo
center line.
Move the throttle stick to the closed position and move the carburetor to closed.
Use a 2.5mm hex wrench to tighten the
screw that secures the throttle pushrod
wire. Make sure to use threadlock on the
screw so it does not vibrate loose.

1) Slide the berglass cowl over the engine and line up the back edge of the cowl
with the marks you made on the fuselage
then trim and cut as shown.
Because of the size of the cowl, it may be necessary to use a needle valve extension for the
high speed needle valve. Make this out of sufcient length 1.5mm wire and install it into
the end of the needle valve. Secure the wire in
place by tightening the set screw in the side of
the needle valve.
3) Install the muer and muer extension
onto the engine and make the cutout in the
cowl for muer clearance. Connect the fuel
and pressure lines to the carburetor, muer
and fuel ller valve. Secure the cowl to fuselage using the M3x10mm screws.
2) While keeping the back edge of the cowl
ush with the marks, align the front of the
cowl with the cranksha of the engine. e
front of the cowl should be positioned so the
cranksha is in nearly the middle of the cowl
opening. Hold the cowl rmly in place using
pieces of masking tape.

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 27MM FORWARD OF THE LEADING EDGE.
Instruction Manual.
2) If the nose of the plane falls, the plane is
nose heavy. To correct this rst 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 sides 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 onto the rewall or use a brass heavy hub spinner hub,
similar to those oered by Harry Higley.
When balanced correctly, the airplane
should sit level or slightly nose down
when you li it up with your ngers.

FLIGHT PREPARATION. PREFLIGHT CHECK.
Instruction Manual.
Check the operation and direction
of the elevator, rudder, ailerons and
throttle.
A) Plug in your radio system per the
manufacturer’s instructions and turn
everything on.
B) Check the elevator rst. Pull
back on the elevator stick. e elevator halves should move up. If it they do
not, ip the servo reversing switch on
your transmitter to change the direction.
C) Check the rudder. Looking from
behind the airplane, move the rudder
stick to the right. e rudder should
move to the right. If it does not, ip
the servo reversing switch on your
transmitter to change the direction.
1) Completely charge your transmitter and receiver batteries before
your rst day of ying.
2) Check every bolt and every glue
joint in the Westland Lysander to en-
sure that everything is tight and well
bonded.
3) Double check the balance of the
airplane. Do this with the fuel tank
empty.
4) Check the control surfaces. All
should move in the correct direction
and not bind in any way.
5) If your radio transmitter is
equipped with dual rate switches
double check that they are on the low
rate setting for your rst few ights.
D) Check the throttle. Moving the
throttle stick forward should open the
carburetor barrel. If it does not, ip the
servo reversing switch on your transmitter to change the direction.
E) From behind the airplane, look
at the aileron on the right wing half.
Move the aileron stick to the right.
e right aileron should move up and
the other aileron should move down.
If it does not, ip the servo reversing
switch on your transmitter to change
the direction.
We wish you many safe and enjoyable ights
6) Check to ensure the control surfaces are moving the proper amount
for both low and high rate settings.
7) Check the receiver antenna.
It should be fully extended and not
coiled up inside the fuselage.
8) Properly balance the propeller.
An out of balance propeller will cause
excessive vibration which could lead
to engine and/or airframe failure.
