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.

Trial fit the horizontal stabilizer in place on the fuselage. Check the alignment
of the horizontal stabilizer. The distance must be equal on both sides
. If not, adjust the stabilizer until the measurements(A=A’ and B=B’ and C=C’)
are the same.
If the fit is overly tight, it may be necessary to
lightly sand the hole on the fuselage.

* 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.

When you are satisfied with the alignment , use a pencil to
carefully trace around the top and bottom of the stabilizer
where it meets the fuselage. Note, it is important not to
disturb the alignment of the stabilizer. The pencil should
leave a light indentation in the covering.
Pencil
Remove the horizontal stabilizer from the fuselage. Using a sharp hobby
knife, carefully cut away the covering inside the lines which were marked
in Step .13A
Be cautious not to cut into the wood-this will weaken the structure.

stabilizer.
When satisfied with the alignment, mark the mounting
hole position, where the rudder torque rod meets the
rudder with a pencil.

Important: When you “on” the retract swicth, if the retract
gear does not retracted completely, you immediately “off”
the retract switch. If the retract gear does not extend, use
your finger to push the retract gear to the completely

Then use the hobby knife to remove the place where the
retract gear is entangled.
