Note:   As  with  all  kits,  it’s  a  good  idea  to  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 as soon as you can.    Make sure you have 
a flat and sturdy workbench and follow all safety advice 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. 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.
