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. We recommend 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. Our 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.
