1- Using a pencil, mark the center of the brace.
2- Trial fit the wing joiner into one of the wing
panels. It should insert smoothly up to the
center line marked above.
3- Slide the other wing half onto the dihedral brace
until the wing panel meet. If the fit is over tight, it
may be necessary to lightly sand the dihedral brace.
4- Check for the correct dihedral angle.
5- Mix approximately 30 minute epoxy and apply a generous amount of epoxy into the wing joiner cavity
of one wing half.
6- Coat one half of the dihedral brace with epoxy up to the center line. Install the epoxy-coated side of
the dihedral brace into the wing joiner cavity up to the center line, marking sure that the “V” of the dihedral brace is positioned correctly
7- Do the same way with the other wing half.
8- Carefully slide the wing halves together, ensuring that they are accurately aligned. Firmly press the
two halves together, allowing the excess epoxy to run out. Clean off the excess epoxy.
WARNING: Please do not clean off the excess epoxy on the wing with strong solvent or pure alcohol, only
use kerosene to keep the colour of your model not fade.

1-Insert the Z-bend into the hole on the throttle lever of your engine. Note: It maybe
easier to temporarily remove the carburetor from the engine to insert the Z-bend.
It may also be necessary to slightly enlarge the hole to accept the Z-bend.

2-Set the engine on the engine mounting beams. Adjust the pacing of the beams
so they are centered in the relation to the mounting plate and so they are almost
touching both sides of the engine crankcase.
3-Position the engine on the engine mount beams so the distance from the prop
hub to the fire wall is 5mm.
4-Using a pencil, mark the engine mounting plate where the four holes are to be
drilled
5-Remove the engine and drill a 9/64”(3.5mm) hole through the beam at each of
the four marks made in step 4 above.
6-Reposition the engine on the mounting beam, aligning it with the holes. Secure
it in place with the four 1/8x25/32”(3x20mm) screws.

Carefully install the fuel tank
to ensure that they will not
shift during flight (secure the
fuel tank in place using foam
padding).
1-Trial fit the horizontal stabilizer in place . Check
the alignment of the horizontal stabilizer. When you
are satisfied with the alignment, use a pencil to
trace around the top and bottom of the stabilizer
where it meets the fuselage.
2-Remove the horizontal stabilizer from the fuselage.
Using the sharp hobby knife, carefully cut away the
covering inside the lines which were marked above.
3-Spread epoxy (30 minute) onto the top and
bottom of the horizontal stabilizer along the area
where the covering was removed and to the fuselage where the horizontal stabilizer mounts.
4-Install the horizontal stabilizer into the fuselage
and adust the alignment as described in steep 1.
Allow the epoxy to cure before proceeding to next
step.
Do the same way with the vertical stabilizer.
9-Vertical / Horizontal Tail
Securely glue together. If coming off
during flight, you lose control of your
air plane.
* WARNING: When removing any covering
from the airframe, please ensure that you
secure the cut edge with CA or similar cement.
This will ensure the covering remain tight.

Check the alignment of the horizontal stabilizer by measuring from a fixed point along the center line of the fuselage to the
leading edge on each side of the horizontal stabilizer. The distance must be equal on both sides. If not, adjust the stabilizer
until the measurements are the same.

Insert the rudder pushrod, threaded end first, into the fuselage
so the threaded rod exits the rudder pushrod slot on the top of
the fuselage.
Screw on clevis 12 ~ 15 complete turns. Fasten the clevis in the
third hole from the inside of the rudder control horn. Mark the
location of the control horn mounting hole positions when you
are satisfied with the alignment.
Remove the rudder control horn and drill these two mounting
holes using 5/64” (2mm) drill bit.
Install the rudder control horn using the two 2x15mm screws
and the back plate.
Do the same way with the elevator control horn.

RANGE TEST YOUR RADIO
Turn on the radio in your plane. With your plane on the ground, you should be able to walk 30 paces away
from your plane and still have complete control of all functions. If not, do NOT attempt to fly.
Be sure that your batteries are fully charged per the instructions included with your radio
FREQUENCE
If your airplane begins to operate by itself, there is another transmitter on your frequency. Immediately stop
your airplane; otherwise you may lose control of it which will result in accidents
BEFORE FLYING
1-Fully extend the transmitter antenna.
2-Switch ON the transmitter.
3-Switch ON the receiver.
4-By moving the control sticks, ensure all control surfaces moves as per your adjustments.
5-By moving the throttle control stick, ensure the carburetor opens and closes without effort.
FLYING
1-Take-off your airplane INTO THE WIND.
2-Do not fly your airplane above people standing around.
AFTER FLYING
1-Always land your airplane INTO THE WIND.
2-Switch OFF the receiver.
3-Switch OFF the transmitter.
CAUTIONS FOR SAFETY
1-Adjust the engine always from behind, but never from infront or the side as a rotating propeller may badly
injure you!
2-Do not allow watching people to get too close to a rotating propeller.
WARNING: Please do not clean your model with pure alcohol, only use liquid soap with water or use class
cleaner to clean on surface of your model to keep the colour not fade.
