Model Rocketry is a fantastic way to learn about the science of flight. It is not our purpose to keep anyone from buying anything on this site, but due to the responsibility needed to build and fly these great kits certain restrictions will apply to the purchase of any kit on the following pages. First you must be at least 14 years old, have parental consent (to age 16), must read and understand ALL the information and safety regulations listed below

 

N.A.R. MODEL ROCKET SAFETY CODE
 

1. MATERIALS. I will use only lightweight, non-metal parts for the nose, body, and fins of my rocket.

2. MOTORS. I will use only certified, commercially-made model rocket motors, and will not tamper with these motors or use them for any purposes except those recommended by the manufacturer.

3. IGNITION SYSTEM. I will launch my rockets with an electrical launch system and electrical motor igniters. My launch system will have a safety interlock in series with the launch switch, and will use a launch switch that returns to the "off" position when released.

4. MISFIRES. If my rocket does not launch when I press the button of my electrical launch system, I will remove the launcher's safety interlock or disconnect its battery, and will wait 60 seconds after the last launch attempt before allowing anyone to approach the rocket.

5. LAUNCH SAFETY. I will use a countdown before launch, and will ensure that everyone is paying attention and is a safe distance of at least 15 feet away when I launch rockets with D motors or smaller, and 30 feet when I launch larger rockets. If I am uncertain about the safety or stability of an untested rocket, I will check the stability before flight and will fly it only after warning spectators and clearing them away to a safe distance.

6. LAUNCHER. I will launch my rocket from a launch rod, tower, or rail that is pointed to within 30 degrees of the vertical to ensure that the rocket flies nearly straight up, and I will use a blast deflector to prevent the motor's exhaust from hitting the ground. To prevent accidental eye injury, I will place launchers so that the end of the launch rod is above eye level or will cap the end of the rod when it is not in use.

7. SIZE. My model rocket will not weigh more than 1500 grams (53 ounces) at liftoff and will not contain more than 125 grams (4.4 ounces) of propellant or 320 N-sec (71.9 pound-seconds) of total impulse. If my model rocket weighs more than one pound (453 grams) at liftoff or has more than 4 ounces (113 grams) of propellant, I will check and comply with Federal Aviation Administration regulations before flying.

8. FLIGHT SAFETY. I will not launch my rocket at targets, into clouds, or near airplanes, and will not put any flammable or explosive payload in my rocket.

9. LAUNCH SITE. I will launch my rocket outdoors, in an open area at least as large as shown in the accompanying table, and in safe weather conditions with wind speeds no greater than 20 miles per hour. I will ensure that there is no dry grass close to the launch pad, and that the launch site does not present risk of grass fires.

LAUNCH SITE DIMENSIONS
Installed Total Impulse (N-sec) Equivalent Motor Type Minimum Site Dimensions (ft)
0.00 - 1.25 1/4A,1/2A 50
1.26 - 2.50 A 100
2.51 - 5.00 B 200
5.01 - 10.00 C 400
10.01 - 20.00 D 500
20.01 - 40.00 E 1,000
40.01 - 80.00 F 1,000
80.01-160.00 G 1,000
160.01-320.00 Two G's 1,500

       10 RECOVERY SYSTEM. I will use a recovery system such as a streamer or parachute in my rocket so that it returns safely and undamaged and can be flown again, and I will use only flame-resistant or fireproof recovery system wadding in my rocket.

       11. RECOVERY SAFETY. I will not attempt to recover my rocket from power lines, tall trees, or other dangerous places.

 

  HOW DO A ESTES MODEL ROCKETS WORK?

 

              Estes model rockets are activity kits designed of lightweight materials such as paper tubing, balsa wood and plastic. Balsa or plastic fins are glued to the body tube for guidance and stability. A model rocket engine holder is also part of the rocket to keep the engine in place during thrust. Estes was the first to develop a mass produced model rocket engine and has produced the engines for over 48 years. The Estes model rocket is propelled into the air by an electrically ignited model rocket engine. After its acceleration, the rocket continues upward emitting tracking smoke as it coasts. At the rocket’s peak altitude (also called apogee), a recovery device, such as a plastic parachute or streamer, is deployed to return the rocket gently to earth.

 

ANATOMY OF AN ESTES ROCKET

 

SKILL LEVELS FOR ESTES ROCKETS
 

READY TO FLY (RTF) : No paint, glue or modeling skills required. Rocket comes assembled and is ready for liftoff
in just minutes.

E2X ROCKET KITS : No paint or special tools needed. E2X kits contain parts that are colored and easy to
assemble. Simply glue the parts together as per the instructions, apply the self-adhesive decals, attach the
recovery system and you are ready to blast off! Assembly usually takes 1 hour or less.

SKILL LEVEL 1 ROCKET KITS : Requires some painting, gluing and sanding. Features laser cut balsa fins, slotted
body tubes, plastic nose cones and self-adhesive decals. Step by step instructions make building very easy. Assembly takes at least an afternoon.

SKILL LEVEL 2 ROCKET KITS : First tier of more advanced kits. Requires beginner skills in model rocket construction
and finishing. Features laser cut balsa or plastic fins, plastic nose cones and unfinished body tubes. Assembly may take a complete day.

SKILL LEVEL 3 ROCKET KITS : Second tier of more advanced kits. Requires moderate skills in model rocket construction and finishing. Features multiple laser cut balsa fins and parts, unfinished body tubes, complex designs and plastic nose cones. Assembly may take a couple of days.
