good power margins and excellent high speed-low speed
characteristics. Using larger engines is not recommended. Larger
engines weigh more and will cause CG problems.
COVERING MATERIAL:
Your Little Extra ARF has been professionally covered using
SIG AEROKOTE-LITE
™
iron-on covering film.
This is a low
temperature covering film that is both very tough and light,
weighing only 5.9 grams per square foot.
For reference, the
AEROKOTE-LITE
™
colors used on this model are:
#SIGSGX204 Cream and #SIGSGX241 Turquoise or
#SIGSGX100 Brilliant White and #SIGSGX360 Violet
If you live in a drier climate, you may notice that some wrinkles
might develop after removing the covered parts from their plastic
bags. This is does not mean that the covering is defective! Your
model was built and covered in a part of the world with relatively
high humidity and therefore the wood was likely carrying a fair
amount of moisture. When exposed to drier air, wood typically
loses this moisture, dimensionally "shrinking" in the process. In
turn this may cause some wrinkles. However, wrinkles are easy to
remove by just using a hobby type heat iron. Remember that with
thin structures, such as the tail group and ailerons, excess heat
will warp them.
Therefore, be careful when applying heat to
remove a wrinkle - a Trim Seal tool, with a small shoe is always
best for these kinds of surfaces - be sure to use the low heat
setting on this tool.
For reshrinking AEROKOTE-LITE
™
set your iron temperature
to approximately 140
O
-180
O
F (60
O
-82
O
C).
Use the iron to go completely over all seams and color joints,
making sure they are all well sealed and secure. If a wrinkle is
found, hold the hot iron over the wrinkle to lightly shrink the
material - do not press on it. Once the covering is tight, lightly iron
it back down to the wood. Be careful with the iron when working
around any seams. Overheating a seam may cause the covering
to creep, exposing the wood beneath. Also, use caution when
working with heat around the canopy area - heat will distort this
clear plastic material.

MODELER'S TIP: A method to avoid damaging seams and
joints when reshrinking the covering is to protect them with
paper towels soaked in cold tap water and rolled into strips.
These are then arranged directly onto the joints or seams and
their coolness protects the seam from shifting or "crawling"
under heat.
