For Your Ultimate Enjoyment and Safety

:

If this is your first ARF or RC model, Golden Skies R/C Aircraft, Inc. (GSRC) recommends that
you seek the knowledge and help of a long time, experienced modeler to assist you in the assembly
of this kit and to assist you in the preflight safety checks and first flights, during which you will be
trimming the plane for safety and performance. Your local hobby shop or the AMA association
(http:www.modelaircraft.org ) can assist you in finding a club, local expertise and a local flying
field. Seek a flying field with an AMA authorized club charter and one that has qualified flying
instructors. This is absolutely mandatory for your safety and the safety of others.
