How To Tighten Loose Covering
After you open your KADET LT-40 and take all the covered parts
out of their plastic bags, the covering may begin to wrinkle. This is
not unusual and is no cause for alarm.
Your airplane was built and covered in a part of the world which
has relatively high humidity and therefore, the wood was likely
carrying a fair amount of moisture. When exposed to drier air, the
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.
CAUTION: Trying to remove the wrinkles by hastily going over
them with a heat gun can lead to more problems. You should take
your time to carefully go over the entire model with a covering iron,
as we will describe.
We suggest using a model airplane covering iron for this process.
Cover the iron's shoe with a thin cotton cloth, such as an old t-shirt,
to prevent scratching the covering as you work.
After covering your iron, the next step is to set the iron to the
correct temperature. This is critical for achieving a good result!
The iron should be set to about 220
O
F - 250
O
F (104
O
C - 121
O
C) as
measured on the bottom of the iron using a thermometer.
If you do not have a thermometer, you can find the correct
temperature by trial and error. Set your iron to a medium setting.
Glide the iron over some of the covering that is over over solid
wood, such as the sheeted wing center section.
Observe the
covering to see if any bubbles appear.
If bubbles appear, the
covering is getting too hot! Turn down the temperature of the iron
and repeat the test.
If no bubbles appear, turn up the heat slightly and repeat the test.
Keep adjusting until you “zero in” on the correct temperature. Find
the temperature that will get the covering to stick down without
forming bubbles or causing the seams to pull away.
Once your iron is set to the correct temperature, go over the
entire framework of the airplane, making sure that the covering is
securely bonded to the structure everywhere the covering comes
in contact with the wood underneath. This takes some time, but is
worth the effort.
After you have all the covering secured onto the solid areas, turn
the temperature of the iron up to approximatelly 300
O
F - 320
O
F
(149
O
C - 160
O
C). This is the correct temperature for shrinking the
covering material.
Use the iron to tighten up any wrinkles in the “open” areas of the
model (no wood underneath the covering). Glide the iron over the
wrinkle for a few seconds, then remove. Repeat until the covering
is tight with no wrinkles.
If wrinkles keep coming back on the tail surfaces, you may need to
“ventilate” the areas between the ribs. Otherwise the air that is
sealed in those relatively small areas will expand when the heat is
applied and actually cause the covering to stretch instead of
shrink. Use a pin to poke a tiny hole in the covering between each
rib, on the bottom of the part. That will let the expanding air
escape and the covering to shrink properly.
Caution When Using Heat Guns: You can also use a hobby-type
heat gun to shrink the covering, but you must be careful around
seams or color joints. Getting too much heat on the seams may
cause them to "creep" or come loose. You must also be careful
when using a heat gun when working around the windshield and
side windows - heat will distort the clear plastic material.
