- Materials. My model rocket will be made of lightweight materials such as paper, wood, rubber, and plastic suitable for the power used and the
performance of my model rocket. I will not use any metal for the nose cone, body, or fins of a model rocket.
- Motors. I will use only commercially-made, NAR-certified model rocket motors in the manner recommended by the manufacturer. I will not alter the model
rocket motor, its parts, or its ingredients in any way.
- Recovery. I will always use a recovery system in my model rocket that will return it safely to the ground so it may be flown again. I will use only
flame-resistant recovery wadding if wadding is required by the design of my model rocket.
- Weight and Power Limits. My model rocket will weigh no more than 1,500 grams (53 ounces) at lift-off and its rocket motors will produce no more than
320 Newton-seconds (71.9 pound-seconds) of total impulse. My model rocket will weigh no more than the motor manufacturerÕs recommended maximum
lift-off weight for the motors used, or I will use motors recommended by the manufacturer for my model rocket.
- Stability. I will check the stability of my model rocket before its first flight, except when launching a model rocket of already proven stability.
- Payloads. My model rocket will never carry live animals (except insects) or a payload that is intended to be flammable, explosive, or harmful.
- Launch Site. I will launch my model rocket outdoors in a cleared area, free of tall trees, power lines, buildings, and dry brush and grass. My launch area will
be at least as large as that recommended in the accompanying table.
- Launcher. I will launch my model rocket from a stable launch device that provides rigid guidance until the model rocket has reached a speed adequate to
ensure a safe flight path. To prevent accidental eye injury, I will always place the launcher so the end of the rod is above eye level or I will cap the end of the
rod when approaching it. I will cap or disassemble my launch rod when not in use and I will never store it in an upright position. My launcher will have a jet
deflector device to prevent the motor exhaust from hitting the ground directly. I will always clear the area around my launch device of brown grass, dry
weeds, or other easy-to-burn materials.
- Ignition System. The system I use to launch my model rocket will be remotely controlled and electrically operated. It will contain a launching switch that
will return to "off" when released. The system will contain a removable safety interlock in series with the launch switch. All persons will remain at least 15 feet
from the model rocket when I am igniting model rocket motors totalling 30 Newton-seconds or less of total impulse and at least 20 feet from the model
rocket when I am igniting model rocket motors totalling more than 30 Newton-seconds of total impulse. I will use only electrical igniters recommended by
the motor manufacturer that will ignite model rocket motors within one second of actuation of the launching switch.
- Launch Safety. I will ensure that people in the launch area are aware of the pending model rocket launch and can see the model rocket's lift-off before I
begin my audible five-second countdown. I will not launch my model rocket so its flight path will carry it against a target. If my model rocket suffers a misfire,
I will not allow anyone to approach it or the launcher until I have made certain that the safety interlock has been removed or that the battery has been
disconnected from the ignition system. I will wait one minute after a misfire before allowing anyone to approach the launcher.
- Flying Conditions. I will launch my model rocket only when the wind is less than 20 miles per hour. I will not launch my model rocket so it flies into clouds,
near aircraft in flight, or in a manner that is hazardous to people or property.
- Pre-Launch Test. When conducting research activities with unproven model rocket designs or methods I will, when possible, determine the reliability of my
model rocket by pre-launch tests. I will conduct the launching of an unproven design in complete isolation from persons not participating in the actual
- Launch Angle. My launch device will be pointed within 30 degrees of vertical. I will never use model rocket motors to propel any device horizontally.
- Recovery Hazards. If a model rocket becomes entangled in a power line or other dangerous place, I will not attempt to retrieve it.
