Note:  As with all kits, to correctly understand the construction of your airplane it is 
important that you read all the instructions and study the parts before you begin 
construction.  Handle the parts of this kit with care so you do not damage any of the 
structure or covering.  Inspect all the parts for any shipping damage and report any 
issues to EG as soon as you can.  Make sure you have a flat and sturdy workbench 
and follow all safety rules for the tools and adhesives you plan to use. 

 

  

 

 

AIRCRAFT COVERING:   

1.  With all ARFs, varying temperatures and storage delays can cause covering material to loosen over 

time and transportation.  EG recommends lightly going over all the covering with a covering iron set 
at medium temperatures.  Be sure to use a soft cover over your iron so you do not scratch the covering 
surface.  Be sure you go over all seams and edges of the covering to assure it is secure to the airframe 
and other covering.  Be careful not to apply too much heat or you may cause bubbles or damage to the 
covering.  A heat gun may also be used along with a soft cotton cloth to shrink and adhere the 
covering.  Again, be extremely careful when using a heat gun.   

2.  Be sure to seal any exposed wood with a thin coating of epoxy to prevent engine oil from soaking 

in.  This is especially important around the engine compartment and servo openings with exposed 
areas.   

3.  Some modelers prefer to seal the hinge gaps using strips of appropriate covering or clear trim tape.  

We have found this to be helpful with models intended for higher speed flight or models with 
unusually large hinge gaps.  EG aircraft utilize a very tight double beveled hinge line and do not 
normally require this step.  Sealing the hinge gaps is therefore left as an option for the modeler.
