Materials: 

 I will use only lightweight, non-metal parts 

for the nose cone, body, and fins of my rockets.

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.

Ignition System:

 

  I  will  launch  my rockets  with  an 

electrical launch system and electrical motor ignitors.  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.

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 it's battery, and 
will wait 60 seconds after the last launch attempt before 
allowing anyone to approach the rocket.

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 to a safe distance.

Launcher:

 

 I will launch my rockets 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 I will cap the end of the rod when 
it is not in use.

Size:  

  My model rocket will not weigh more than 1,500 

grams (53 oz) at liftoff, and will not contain more than 125 
grams (4.4 oz) of propellant or 320 N-sec (71.9 lb-sec) of 
total impulse. If my model weighs more than one pound 
(453 grams) at liftoff, or has more than four ounces (113 
grams) of propellant, I will check and comply with Federal 
Aviation Administration (FAA) regulations before flying.

Flight Safety:

 

 I will not launch my rockets at targets, 

into   clouds,   or   near   airplanes,   and   will   not   put   any 
flammable or explosive payload into my rockets.

Launch Site:

 

 I will launch my rockets outdoors, in an 

open area at least as large as  shown below, and in safe 
weather conditions with winds speeds no greater than 20 
MPH. 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.

Recovery System:

 

 I will use a recovery system, such 

as   a   streamer   or   parachute,   in   my   rockets   so   that   they 
return safely and undamaged and can be flown again, and 
I will use only flame-resistant or fireproof recovery system 
wadding in my rockets.

Recovery Safety:  

  I will not attempt to recover my 

rocket   from   power   lines,   tall   trees,   or   other   dangerous 
places.
