The covering material used on the WattAge PT-19 Cornell EP ARF is real iron-on, heat-shrink covering material. It is possible
with heat and humidity changes that the covering on your airplane may wrinkle or sag. This trait is inherent in all types of heat-
shrink material. To remove any wrinkles that might be visible you will need to use a heat-sealing covering iron.
Follow this simple procedure to remove the wrinkles:
❑
Plug in and turn on the sealing iron to the medium-high temperature setting. Allow the sealing iron to heat up for approximately
5 - 7 minutes.
❑
After the sealing iron has reached temperature, lightly apply the sealing iron to the wrinkled section of the covering. Move the
sealing iron slowly over the wrinkled section until the covering tightens and the wrinkles disappear.

You will notice that the color of the covering will darken when it is heated. When the covering cools back down,
it will return to its normal color.
☞
If the color layer smears from any of the seams the temperature of the sealing iron is too hot. Turn the temperature dial down
and wait about 5 minutes for the sealing iron to adjust to the lower temperature. You can remove any excess color streaks using a
paper towel soaked with a small quantity of Acetone.
We do not suggest storing your airplane in an extremely hot environment (like the back of your car in direct sunlight)
for any length of time. The extreme heat could distort the molded plastic fuselage and/or cause the covering material to wrinkle
and possibly damage the fragile components of the radio system, ESC or flight battery.
WARNING ABOUT PLASTIC PARTS
The fuselage, cowling and landing gear strut fairings of your PT-19 Cornell EP ARF are painted. Do not use any harsh chemical
cleaners, such as Acetone, to clean the painted surfaces. Use of rubbing alcohol is okay and will not damage the paint.
