Your Great Planes Piper J-3 Cub 20 is not a toy, but
rather a sophisticated, working model that functions very
much like an actual airplane.
Because of its realistic performance, the Cub 20, if not
assembled and operated correctly, could possibly cause
injury to yourself or spectators and damage property.
To make your R/C modeling experience totally
enjoyable, we recommend that you get experienced,
knowledgeable help with assembly and during your
first flights. You'll learn faster and avoid risking your model
before you're truly ready to solo. Your local hobby shop has
information about flying clubs in your area whose
membership includes qualified instructors.
You can also contact the national Academy of Model
Aeronautics (AMA), which has more than 2,300 chartered
clubs across the country. Through any one of them,
instructor training programs and insured newcomer training
are available.
