ASSEMBLY INSTRUCTION
Step 1. Installation in the
wings
1. Glue the aileron hinges in place
Take out the wings and ailerons,
insert the hinges into the factory cut
hinges slots in the wings and
ailerons. Careful to glue them
together by dropping CA into the
gap at the location of each hinge.
2. Install the aileron servos
Test fit your servo in the aileron
servo mount and enlarge the opening
if necessary. Pull the servo wire
through the hole and screw the servo
to the servo mount using the screws
supplied with the servo. Mount the
servo with the servo arm toward the
rear. Remove the string from the servo wire.
3.Install the aileron control horns
Slip the screw through the aileron
from the top and then reinstall the
washer and nut. Tighten the nut
using a thread locking compound or
CA to make sure it does not loosen.
4.Install the aileron pushrod
Locate the pushrods and clevis.
Attach the clevis end of the pushrod to the aileron control horn, slip a
clevis onto the other end of the pushrod and attaché that clevis to the
outer hole in the servo arm.

Step 2. Installation Landing gear
1. Notice that the mounting flange
of the wheel pant has a plywood
mounting pad installed at the front
and rear. Drill a hole through the
center of each pad. Also cut
through the mounting flange just
above the slot in the side of each
pant.
2.Test fit the prefabricated wire
gear struts in the mounting slots in
the wings.
3.When the struts fit nicely into the
mounts, position the metal gear
straps and drill pilot holes. Attach
the straps with self-tapping screws.
4.Now remove the struts from the
wings and slide them into the
wheel pants. Push the strut all the
way to the bottom of the slot so
that the axle protrudes out of the
bottom of the pant.
5.Connect two clevis ends of flying
wires to upper and lower wing
struts side flying wire connectors,
one on front and one on rear.
Connect one clevis end to lower
wing connector near fuselage and
upper center section rear cabane
flying wire connectors. Do same
way to other wing panel.
6.Pull the strut as far into the slot as
the wheel will let it go and reinstall the strut and gear straps. Slide the
wheel pant down onto the wing and line up the front and rear mounting

8
holes with the center of the rubber
mounting pads in the wing. Drill a
pilot hole through the mounting
holes in the pant, through the rubber
pad and into the plywood
underneath.
Step3. Assemble the tail surfaces
1. Bolt the wing onto the fuselage
and set the airplane in a position so
that you can sight over the
horizontal stab and wing together.
After this, be careful to glue them by
dropping CA into gap at the location
of each hinge.
2. There are three holes we have
provided in factory, use three screws
to fix the plastic control horn on the
rudder and elevator.
3. Slip the Elevator into the slot on
the fuselage, and then insert the
hinge of fan into the factory cut
hinge slots. After this, be careful to
glue them together by dropping CA
into gap at the location of each hinge.
Seeing the slot between the vertical
stabilizer and elevator is vertical
with the middle line of fuselage, and
the vertical stabilizer should be gone
halves with the midline of fuselage.
It can be sure the elevator is on the
right situation of the fuselage. Then be careful to glue the vertical
stabilizer on the fuselage tighter.

4.Hold the bracket over the rear end
of the fuselage and drill holes
through the front and rear mounting
holes. Screw the bracket in place
with the two washer head
self-tapping screws provider. Push
the wheel collar up under the bracket
and tighten the setscrew to hold it in
place.
5.Take the Rudder control pull-pull
cable, insert it into the tube in the
fuselage, perforate at the end of the
tube, take the cable out of the
fuselage, and then drill through the
hole of the plastic clevis, clamp the
cable with a copper tube using pliers.
Attach the clevis end of the pushrod to the hole of the plastic control
horn.
6. Take out the Elevator pushrod. Fit
you miniature servos in the elevator
servo mounts and enlarges the
opening if necessary. Pull the servo
wire through the fuselage and out he
hole in the middle of fuselage that
can be linked with receiver. You will
need to add an extension to the end
of your rudder and elevator servo
wires. Locate the rudder and
elevator pushrods and slip the “Z”
bend through the hole in the servo
arm. Attach the clevis end of the
pushrod to the hole of the plastic
control horn.

Step4. Install the engine
1. Firstly, try fit the engine cowl to
the fuselage head. Using a straight
ruler, insert it through the front
opening of the cowl until it touches
firewall. Thus, you can measure the
distance D between the front edge of
the cowl and the firewall. And then,
remove the cowl. Cut any necessary
opening in the cowl.
2. Fix the engine tightly onto its
mount with the 4 pcs mounting bolt,
washer, self-lock nut.
3. Insert the Z-end of the throttle
pushrod into the hole in the engine
carburetor arm. And then, hold the
complete engine along with throttle
pushrod and insert the unthreaded
end of the pushrod through the hole
in the firewall in order to connect the
throttle servo-arm.
4. The fuel tank is bundled by four
Velcro strap on the fuselage tightly.

11
Step5. Mount the Receiver and Battery onto the fuselage
1. Fit the battery on the battery rack
on the bottom of fuselage, and
bundle tightly with Velcro strap.
Please note the position of battery in
the fuselage should be base on the
C.G point. Cover the battery rack
cover on the fuselage after fixing the
battery on the fuselage.
2. Connect the Motor, ESC and
battery together, and then insert the
ESC into the fuselage.
3. Install the two rudder control
pull-pull cable into fuselage.
4. Covering the engine cowl on the
motor in order to measure if the
motor on the correct position. With
4pcs of self-tapping screws screw
you can mount the motor cowl on
the fuselage. And then install the
propeller and spinner on the motor.
Step 6. Mount the wing onto the fuselage
Locate the carbon fiber dowel and
the aluminum wing tube. Remove
any protective film from the wing
tube and file off any burrs or sharp
edge on the ends. Slip the tube into
each wing separately. Slip the carbon
fiber dowel into the factory-drilled
hole in one wing and slide the wings
together. The wings should fit together snugly at the center and line up

12
properly at the trailing edge. Take
the wings apart and rough up the
surface of one of the dowel with a
course file or a cut-off wheel.
Finally, with 6pcs self-tapping
screws mount the canopy in place on
the cockpit.
At last, adjust the wing and fuselage configuration as in the diagrams
carefully.

Step 7. Final check before flying
You have finished your model airplane, but you have to check before
flying.
1. Check the alignment and trim of the airplane after final assembly.
2. Check that everything is tightly securely.
3. Check the C.G. point, which must be 83mm (3.27 in.) behind the
leading edge measured at the center of the upper wing center section.
In order to obtain the C.G specified, add weight to the fuselage or
move the battery position. Check the C.G. before flying.
4. Make sure that the servos operate properly and the control surfaces
move in the correct direction.
5. Make sure that the model is balanced laterally. Add weight to a wing
tip if necessary.
6. The travel of each control surface depends upon your piloting skill
level and flying style. We recommend the following to begin with:
Elevator: 10 mm up/down
Rudder: 30 mm left/right
Ailerons: 5 mm up/down
7. Radio and motor check as follows:
Antenna collapsed, transmitter and receiver switched off
Make sure that the throttle stick is at its lowest position
Turn on the transmitter first, and then the receiver.
Move the controls to make sure that they all function correctly
Walk away from your model for at least 100 feet (30 meters).
Slowly and steadily move the controls and have an assistant watch
for elevator, rudder, or ailerons flutter. Refrain from fast sharp
movements.
Repeat the same control check with the engine running at idle as
well as full throttle. This safety check may reveal a faulty receiver,
servo or wiring/switch problems which only occur with vibration.
Don’t forget to extend the antenna of your transmitter to its full
length before you start flying.
Make sure that nobody is using your frequency.
Good luck and happy flying!
