3Seare Instruction Manual
Thank you for choosing the EScale Seare ARTF. The EScale Seare 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. 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 nd that most of the work has been done for you already. The motor mount has been tted and the
hinges are pre-installed. Flying the EScale Seare is simply a joy.
This instruction manual is designed to help you build a great ying aeroplane. Please read this manual thoroughly
before starting assembly of your EScale Seare . Use the parts listing below to identify all parts.

The control surfaces, including the
ailerons, elevators, and rudder , are
prehinged with hinges installed, but
the hinges are not glued in place. It
is imperative that you properly
adhere the hinges in place per the
steps that follow using a high-quality
thin C/A glue.
2) Remove each hinge from the wing panel
and aileron and place a T-pin in the center of
each hinge. Slide each hinge into the aileron
until the T-pin is snug against the aileron. This
will help ensure an equal amount of hinge is
on either side of the hinge line when the aileron
is mounted to the wing panel.
HINGING THE AILERONS
Note:
1) Carefully remove the aileron from one
of the wing panels. Note the position of the
hinges.
Hinge.
3) Slide the aileron on the wing panel 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
should be maintained between the wing panel
and aileron.

8) After both ailerons 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.
6) Using C/A remover/debonder and a
paper towel, remove any excess C/A glue that
may have accumulated on the wing or in the
aileron hinge area.
5) Turn the wing panel over and deflect the
aileron in the opposite direction from the
opposite side. Apply thin C/A glue to each
hinge, making sure that the C/A penetrates into
both the aileron and wing panel.
Work the aileron up and down several
times to “work in” the hinges and
check for proper movement.
Note:
HINGING THE ELEVATOR
Glue the elevator hinges in place using the
same techniques used to hinge the ailerons.
4) Deflect the aileron and completely
saturate each hinge with thin C/A glue. The
ailerons front surface should lightly contact the
wing during this procedure. Ideally, when the
hinges are glued in place, a 1/64” gap or less
will be maintained throughout the length of the
aileron to the wing panel hinge line.
The hinge is constructed of a special
material that allows the C/A to wick
or penetrate and distribute
throughout the hinge, securely
bonding it to the wood structure of
the wing panel and aileron.

ENGINE MOUNT INSTALLATION
1) Locate the items necessary to install the
engine mount included with your model.
2) Use four 4x30mm head bolts and four 4mm
washers to attach the engine mount rails to
the firewall. Tighten the screws. Make sure to
use threadlock on the screws to help prevent
them from vibrating loose.
4x30mm.
Thread locker glue.
1) Using a modelling 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.
INSTALLING THE STOPPER ASSEMBLY
2) Using a modelling 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.

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
.
3) Carefully bend the second nylon tube
up at a 45º angle. This tube is the vent 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
modelling knife. If flashing is present, make
sure none falls into the tank.
Vent tube. Fuel pick up tube.
Fuel fill tube.
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. The 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 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
7) Slide the fuel tank into the fuselage. Guide
the lines from the tank through the hole in the
firewall.

3) Secure the servos with the screws pro-
vided with your radio system.
Because the size of servos differ , you
may need to adjust the size of the precut open-
ing in the mount. The notch in the sides of the
mount allow the servo lead to pass through.

8) 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.
9) 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.
COWLING
Trim and cut.
1) Slide the fiberglass 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.

7) Slide the throttle pushrod wire into the tube.
Position the engine between the mounts. Use
four M4x30mm machine screws to secure the
engine to the mount as shown.
5) Slide the pushrod tube in the firewall and
guide it through the fuel tank mount. Use
medium C/A to glue the tube to the firewall and
the fuel tank mount.
6) Connect the Z-bend in the 450mm throttle
pushrod to the outer hole of the carburetor arm.

Because of the size of the cowl, it may be nec-
essary to use a needle valve extension for the
high speed needle valve. Make this out of suf-
ficient 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.
Machine screw M3x10mm.

3) Install the muffler and muffler extension
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. Secure the cowl to fuse-
lage using the M3x10mm screws.
2) While keeping the back edge of the
cowl flush with the marks, align the front of
the cowl with the crankshaft of the engine. The
front of the cowl should be positioned so the
crankshaft is in nearly the middle of the cowl
opening. Use the spinner backplate as a guide.
Hold the cowl firmly in place using pieces of
masking tape.

ELECTRIC POWER CONVERSION
1) Locate the items necessary to install the
electric power conversion included with your
model.

3) Use drill bit in a pin vise to drill the mouting
holes in the blocks.
4) Apply 2-3 drops of thin C/A to each of the
mounting holes. Allow the C/A to cure without
using accelerator.
6) Secure the servo to the aileron hatch using
Phillips screwdriver and the screws provided
with the servo.
5) Use dental floss to secure the connection
so they cannot become unplugged.
7) Apply 1-2 drops of thin C/A to each of the
mounting tabs. Allow the C/A to cure without
using accelerator.

Small weight.
1) Using a small weight (Weighted fuel pick-up
works well) and string, feed the string through
the wing as indicated.
2) Place the servo between the mounting
blocks and space it from the hatch. Use a pencil
to mark the mounting hole locations on the
blocks.
Because the size of servos differ , you
may need to adjust the size of the precut open-
ing in the mount. The notch in the sides of
the mount allow the servo lead to pass through.
