If exposed to direct sunlight and / or heat, wrinkles can appear. Storing the model in a coll
place will let the wrinkles disappear. Otherwise, remove wrinkles in covering film with a hair-
dryer, starting with low temperature. You can fix the corners by using a hot iron.

securely, If not properly
glued, a failure in flight may occur.
2- Joining the wing
AB
Draw the center line
on the wing joiner
- Trial fit each part before gluing . Be certain that there are no gaps.
If the parts will join, but with a gaps, sand or trim the parts a little
at a time until the parts meet exactly with no gaps.
- Check for the correct dihedral angle

Before gluing:
- Draw the center line on the wing joiner.
Note: The two wing halves roots must fit together perfectly.
IMPORTANT:
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.

3-Aileron servo installation
1-Cut away the covering of the wing bottom
where the aileron servo goes.
2-Connect the aileron servo cord to the aileron
extension cord.
3-Install the aileron servo on the servo mount.

AILERON
Depending on the position of
the linkage, determine the location
of aileron control horn.
The horn holes must be perfectly aligned
with the axis of articulation.
Mark the position of the “foot” of the horn on the
aileron. Then, with the drill, make the 2 holes.
Install the aileron control horn as shown.

1- Locate the main landing gear struts and place
them into the landing gear slot as show. Make
sure that the ends of the struts are inserted into
the holes in the landing gear channel.
2- Position the four nylon straps across the landing
gear struts. Using the eight 3x12mm screws
located in the hardware bag, fasten the landing
gear to the bottom of the wing as show.
3- Slide one wheel onto each of the
landing gear axles and secure them
with the supplied wheel collars
* 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.
Cut away only the
covering both the
left and right side*
Note: 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.
1-Slide the vertical and horizontal stabilizer on the fuselage, use a pencil to trace
around the bottom and the top (horizontal stabilizer) and the right and the left
(vertical stabilizer).
2-Remove the vertical and horizontal stabilizer from the fuselage. Careful cut
away the covering inside the lines which were marked in steep 1.
Cut away only the covering both
the top and bottom side*
Realign the vertical stabilizer and horizontal stabilizer, then glue
the vertical stabilizer and horizontal stabilizer into the fuselage,
using a generous amount of thin CA.
Note: glue both the right and left of the vertical stabilizer, and
both the top and bottom of the horizontal stabilizer.

When satisfied with the and alignment, hinge the elevator to the horizontal stabilizer using thin CA glue.
Do the same way with other elevator and rudder.

Checking for leaks - block the
vents and blow into the feed -
if in doubt submersing the tank

Carefully install the fuel tank to ensure that they will not
shift during flight (secure the fuel tank in place using foam padding).
2-Secure foam padding with rubber bands or tape.
3-Shift the location of the receiver and battery pack as
