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.
