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.
Bei Sonneneinstrahlung und/oder Wärme kann die Folie erschlaffen bzw. Falten
entstehen. Verwenden Sie ein Warumluftgebläse (Haartrockner) um evtl. Falten aus der Folie
zu bekommen. Die Kanten können Sie mit einem Bügeleisen behandeln. Nicht zuviel Hitze anwenden !

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.

Carefully install the fuel tank
to ensure that they will not
shift during flight (10C).
Checking for leaks - block the vents and blow into the
feed - if in doubt submersing the tank in a blow of
water will show up any problems (10B).
11-HORIZONTAL STABILIZER
Cut away only
the covering
Using a sharp hobby knife, carefully cut away the covering
around of all slots for the horizontal stabilizer and vertical
fin installation.
Pull the left and right elevator out of the horizontal stabilizer.
Push the horizontal stabilizer into the slot on the fuselage
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)

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).
! Securely glue together. If coming off during fly, you lose control of your air plane.
12-VERTICAL STABILIZER
Pull the rudder out of the vertical fin.
Carefully, push the vertical fin into the
slot on the fuselage as shown (12A).
12A
Trial fit the vertical fin in position. Using
a 90 degree triangle, ensure that the
vertical stabilizer is perpendicular to the
horizontal stabilizer (12B).
Using a pencil, trace around the vertical
stabilizer where it meets the fuselage.
Remove the vertical stabilizer from the
fuselage. Using s sharp hobby knife,
carefully cut away the covering below the
lines which were drawn in the previous
steep. Do not cut into the woods as this
will affect the structural integrity of the
stabilizer (12C).

Remove the rudder and drill a 2mm diameter
hole in torque rod mounting slot, making sure that you
drill the hole perpendicular to the leading edge of the
