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

- Check for the correct dihedral angle
Hold the wing halves together with paper clamp and rubber band.
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.

Carefully, push the horizontal stabilizer into the slot on the
fuselage as show.
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.
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.
Pull the left and right elevator out of the horizontal stabilizer.
Using a sharp hobby knife, carefully cut away the covering
