UNPACK

damage, please contact 3DHobbyShop to discuss. 
 
WRINKLES 
 
Your airplane was packed in plastic at the factory without any wrinkles in the covering.  You may notice 
some wrinkles now; more likely, you will notice a few in a day or two or the first time you take the plane 
out to the flying field.  These wrinkles are the result of wood shrinkage and/or expansion.  Balsa wood 
changes size and shape slightly as it is exposed to varying humidity in the air.  This is a natural property 
of balsa wood.  As your airplane adjusts to the weather in your part of the world, wrinkles may appear and 
disappear.  Wrinkles may be removed with the gentle application of heat to the covering material on your 
airplane.  The best tools to use are a heat gun and covering iron.  Apply the heat gently: the covering 
material will shrink as you apply the heat, and this will remove the wrinkles.  BE CAREFUL!  Too much 
heat applied too quickly can damage the covering, either by causing it to pull away from the wood at 
seams and corners or even by melting it.  The covering will shrink at low temperature with patient 
application of heat.  

Wrinkles in the covering DO NOT affect flight performance.  

If you are shrinking 

inside a large area of one color, and not at a seam, the heat gun is the best choice.  If you must shrink on 
a color-seam, use the iron and go slowly and carefully to avoid any pulling or lifting at the seam. 
 
Remove the canopy before attempting to use heat on your covering!  The canopy is made of thermo-
activated plastic and WILL deform with the application of heat.  Do not apply heat to the canopy. 
PAINT 
 
If you need to clean your airplane, we recommend using a damp towel.  The paint used on the canopy 
and cowl is not safe for all cleaners.  In particular, DO NOT use alcohol on these parts, it will remove the 
paint.
