SAFETY INSTRUCTIONS
For the safe and reliable performance of your model rocket
PLEASE NOTE:
1.
That model rockets are not "toys" - that they are capable of causing
personal injury to you and to others as well as property damage.
2.
That you and you alone are responsible for the safe operation of
your rocket.
3.
That you must properly build and operate your model with a clear
sense of that responsibility; that means taking no chances or risks
which might endanger yourself or others.
4.
That you read and observe the rules of the Model Rocketry Safety
Code printed on the back of the cardboard insert included in your kit.
Remember, the thrill of rocketry lies in the safe construction of the rocket
and in its careful operation. Make each launch a success and you will be
proud of yourself and will really enjoy your hobby.

Cut out the shock cord holder on page 3 of the instructions. After it has
been cut out, make two slits with your modelers knife on two dotted lines.
Do not make slits any wider than is marked by the dotted lines. Feed the
shock cord through the two slits as indicated in the drawing and put a small
knot at the end of the shock cord. Apply white glue to Section B and fold A
onto B along the large dotted line. Allow to dry.
