If exposed to direct sunlight and/or heat, wrinkels can appear. Storing the
model in a cool 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.

Using a pencil, mark the center of the brace.
This mark will serve as the center line when
joining the wing halves.
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, making sure that the “V” of the
dihedral brace is positioned correctly.
Apply the generous amount of epoxy into the wing cavity of the center
wing.
Smear epoxy on all sides of the exposed area of the dihedral brace
and uniformly coat both wing roots with epoxy.
Carefully slide the wing halves together, ensuring that they are
accurately aligned.
Firmly press the two wing halves together, allowing the excess epoxy
to run out. Using kerosene and paper towel, clean off the excess
epoxy
WARNING: Securely glue together, if coming of
during flights, you lose control of your plane
which lead to accidents.
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.

as show. 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 (see picture below: A=A’).
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 (11B)

Remove the horizontal stabilizer
from the fuselage. Using a straight edge
and a sharp hobby knife, carefully cut away
the covering inside the lines which were marked
above. Be cautious not to cut into the wood-this
will weaken the structure (11C)
Install the horizontal stabilizer onto the fuselage and adjust
the alignment as described in steep 11A.
Note: it is important to ensure that the horizontal stabilizer is also level in regards to
the fuselage.
Apply the thin CA along the area where the covering was removed in the previous
step and to the fuselage where the horizontal stabilizer mounts (11D).
Pull the left and right elevator out of the horizontal stabilizer.

Remove the vertical stabilizer from the
fuselage. Using s sharp hobby knife,
carefully cut away the covering below the
