PROTECT YOUR MODEL, YOURSELF

AND OTHERS; FOLLOW THESE 

IMPORTANT SAFETY PRECAUTIONS

Your Piper J-3 Cub plane is not a toy, but rather 
a sophisticated, working model that functions 
very much like an actual airplane. Because of its 
realistic performance, the model, if not assembled 
and operated correctly, could possibly cause injury 
to yourself and spectators or damage property.

We highly recommend that you get experienced, 
knowledgeable help with assembly and during your 
fi rst  fl ights, to make your R/C modeling experience 
totally enjoyable.

 You’ll learn faster and avoid risking 

your model before you’re truly ready to solo. Your 
local hobby shop has information about fl ying clubs 
in your area whose membership includes qualifi ed 
instructors. You can also contact the national 

Academy 

of Model Aeronautics

 (AMA), which has more than 

2,500 chartered clubs across the country. Instructor 
training programs and insured newcomer training 
are available through any one of these clubs.

Contact the AMA at the address or toll-free phone

PRECAUTIONS

1. Assemble the plane 

according to the instructions. 

Do not

 alter or modify the model. If you make any 

modifi cations, you will void your warranty.

2. 

Test

 the operation of the model 

before each fl ight

 

to insure that all equipment is operating properly, 
and that the model remains structurally sound.

3. Fly only on calm days (with wind speeds less 
than 5 mph) and in large open areas free of trees, 
people, buildings or any other obstacles.

Remember: Take your time and follow the instructions 
to end up with a well-built model that is durable and 
easy to fl y.

The R/C model hobby becomes more and more 
enjoyable as your experience grows. Your chances 
for success and graduation to higher levels are 
very good if you take your time and follow the 
assembly and fl ying instructions carefully and 
completely. We hope you enjoy fl ying your Piper 
J-3 Cub plane.
