   INTRODUCTION TO REC.MODELS.ROCKETS AND THIS FAQ

   Rec.models.rockets (r.m.r) is a Usenet newsgroup created for discussions
and topics
   related to model and high-power rocketry.  The purpose of this newsgroup
is for the
   exchange of information between anyone wanting to build, fly, or use
model rockets or
   high power rockets. These are viable alternatives to amateur
rocketry.  The term "model
   rocket" is defined based on non-metalic structural components, weight,
propellant and
   total impulse restrictions, electrical ignition, recovery devices, and
factory-made, solid
   propellant engines. The term "High power rocket" refers to any rocket
using model rocket
   technology (as described above) except without the weight, propellant,
and total impulse
   restrictions of model rocketry.  Amateur rocketry, pyrotechnics, rocket
motor-making, and
   "EX" rocketry are related topics that fall outside of the scope of this
newsgroup.

   This FAQ (list of Frequently Asked Questions) is an attempt to compile a
number of questions
   and suggestions that have been repeatedly posted to r.m.r into a single,
quickly readable document.
   This document was NOT meant to be a 'how to' on any form of
non-professional rocketry  It's hoped
   that it might be of use in answering some of the more commonly asked
questions, summarizing some
   good tips and suggestions, and directing the reader to other documents,
books, sources, etc., where
   more information may be found.  The FAQ has evolved into something
monstrous (and very informative).
   For this reason, only this introduction and the first three sections of
the FAQ will be posted biweekly.
   The entire FAQ will make its appearance on r.m.r. monthly.

   This FAQ is organized as a list of primary topics (see the Table of
Contents below) with a number of
   questions and answers under each.  The majority of this document deals
with, but is not limited to,
   consumer rocketry in the United States and Canada.

     This entire FAQ is available on the web.

Rec.Models.Rockets FAQ (Frequently Asked Questions): PART 1 OF 14

GENERAL INFORMATION

This portion of the r.m.r FAQ is maintained by Buzz McDermott, at
bmcde...@ix.netcom.com. Comments, criticisms, suggestions and corrections
for this section should be sent to that email address.

1.1  What, exactly, is a 'model rocket' versus a 'high power' rocket?  Where do
     liquid fueled and homemade rocket motors fit in?  What about amateur
     rockets?

   'Model', 'high power', 'advanced', and 'amateur' are all terms which have
   many definitions, depending to whom you are speaking. In r.m.r., and in the
   FAQ documents, the definitions (if any) accepted by the NFPA, National
   Association of Rocketry, and Tripoli High Power Rocketry Association are
   used. If these definitions conflict the NAR definition is used.

   'Model rockets' are rockets that conform to the guidelines and restrictions
   defined in the NFPA 1122 document. These rockets weigh less than 1500
   grams, contain less than 125 grams of total fuel, have no motor with
   more than 62.5 grams of fuel or more than 160 NS of total impulse, use
   only pre-manufactured, solid propellant motors, and do not use metal
   body tubes, nose cones or fins. One inconsistency with this is the
   CPSC definition of a model rocket motor, which by their definition must
   contain no more than 80NS total impulse. NFPA document 1127-94 contains
   the most complete definition of a model rocket and the model rocket safety
   code. This is the same safety code as adopted by the NAR.

   'Large Model Rockets' is a term used in the FAA FAR 101 regulations.  It
   refers to NAR/NFPA model rockets that are between 454 and 1500 grams
   (1 to 3.3 pounds) total liftoff weight or contains more than 113 grams
   but less than 125 grams of total fuel.

   'High power rockets' are rockets that exceed the total weight, total
   propellant or single motor total impulse restrictions of model rockets,
   but otherwise conform to the same guidelines for construction materials
   and pre-manufactured, commericially made rocket motors. High power rockets
   also allow the use of metal structural components where such a material
   is necessary to insure structural integrity of the rocket. High power
   rockets have no total weight limits, but do have a single motor limit of
   no more than O power (40,960NS maximum total impulse) and have a total
   power limitation of 81,920NS total impulse. NFPA document 1127-1985 contains
   the most complete definition of a high power rocket and also the high power
   rocketry safety code. This safety code has been adopted by both the NAR
   and TRA. Metal bodied rockets are allowed by NFPA 1127 where metal is
   required to insure structural integrity of the rocket over all of its
   anticipated flight.

   'Amateur' rockets covers all other non-professional rockets that do not
   meet the criteria for model or high power rockets. This includes metal
   bodied rockets, liquid or hybrid fueled rockets, and rockets with any
   type of homemade rocket motor.

   'Experimental' rockets is an ambiguous term.  In the early 1980's it
   was used (reportedly coined by the magazine 'California Rocketry') to
   describe rockets that exceeded the model rocket limit at that time (1
   pound total liftoff weight and no motor above F power).  More recently,
   it has been used by the Tripoli Rocketry Association to describe the
   class of rockets that use pre-manufactured solid or hybrid rocket
   motors but that do not qualify as high power rockets.  This includes
   metal bodied rockets and those with more than 80,000NS of total
   power.

   'HPR-lite' is not any type of 'official' rocket designation but has been
   used to refer to rockets that exceed the old NFPA model rocket limit of
   1 pound but still qualify as NFPA model rocket under current guidelines.
   These rockets typically use E through G power and are built with much
   the same techniques as high power rockets.  This term originated in the
   internet 'rec.models.rockets' newsgroup. It should be noted that this
   term refers to legal model rockets, not any type of high power rocket,
   and might therefore be misleading to many. The term 'Large Model Rocket'
   should be used instead.

   Another term that has no formal definition but is more and more being
   used in the literature is 'hobby rocketry'. This term includes both
   model and high power rockets, but excludes amateur rockets. The
   term 'consumer rocketry' has also been used, and means the same thing.

   The term 'non-professional rocketry' encompasses all forms of model,
   high power and amateur rocketry.

   Finally, the editor of this document wishes to get on his soapbox for
   just one moment and add the term 'stupid rocketry' to cover all those
   who attempt to casually produce their own rocket fuel and/or motors
   without the benefit of very serious study, and implementation, of the
   processes involved and safety measures required. Especially note
   that this comment is NOT aimed at serious amateur rocketry
   organizations, college level research, etc. End of soapbox.
-------------------------------------------------
1.2  NFPA, FAA, DOT, ... Who are all these organizations and how do they
      affect the rocketry hobby?

    DOT   (Dept. of Transportation) regulates shipping of rocket motors and
          reloads.
    CPSC  (Consumer Products Safety Commission) regulates what may and not
          be sold as a 'consumer' items at the retail level.
    FAA   (Federal Aviation Administration) is responsible for airspace
          control and regulates flights of rockets that exceed 1 pound and
          enter FAA regulated airspace.
    NFPA  (National Fire Protection Association) makes recommendations for
          use of non-professional rocket motors. Although the NFPA only
          makes recommendations, most state and local laws concerning the
          use of model rockets are based, at least in part, on NFPA
          recommendations; especially NFPA 1122.  The NFPA also has a draft
          definition and safety code for High Power rockets, NFPA 1127.
    BATF  (Bureau of Alcohol, Tobacco  and Firearms) has responsibility for
          regulations concerning storage and use of explosives. This agency
          has taken a recent interest in looking into how high power rocket
          motors are stored and used.
    ATC   (Air Traffic Control) You must notify the nearest FAA ATC center
          prior to flying Large Model Rockets or High Power Rockets.
-------------------------------------------------
1.3    What is the current legal status of model and high power rocketry in the
       U.S.?

   A. FAA Regulations:
      * Rockets containing less than 113 grams of total fuel and weigh
        less and one (1) pound do not require any type of FAA notification
        and are not restricted by the FAA except where they pose a threat
        to aircraft.
      * FAA "large model rockets" (see the definition in #1, above)
        require that the nearest Air Traffic Control center (ATC) be
        notified of the launch between 24 and 48 hours prior to the
        launch. This is notification and not permission. In the U.S., try
        calling 1-800-WX-BRIEF to get the number of the ATC center nearest
        you.
      * FAA High power rockets (weighing more than 3.3 pounds, containing
        HPR motors, or containing a total of more than 125 grams of
        fuel) require a formal waiver be approved by the FAA and activated
        prior to the launch. Refer to the full r.m.r FAQ (dated 1 Oct 94
        or later) for more complete details.
      * NOTE THAT THE FAA DOES NOT PLACE ANY RESTRICTIONS ON FUEL-PER-
        MOTOR OTHER THAN THE TOTAL LIMIT OF FUEL. HOWEVER, MOTORS WITH
        MORE THAN 62.5 GRAMS OF FUEL ARE HIGH POWER ROCKET MOTORS AND
        REQUIRE HIGH POWER CERTIFICATION TO FLY. This does allow HPR
        certified flyers to conduct low-end HPR launches (with up to about
        240NS composite motors) without having to obtain a waiver.
      * Remember that HPR waivers, ATC notification and high power
        certification are all separate issues and must all be properly
        followed.
    B. CPSC Regulations/Restrictions:
       * G class model rocket motors (80.01-160.00NS total impulse) have been
         classified as high power by the CPSC. They are considered model
         rocket motors by the NFPA. These motors are now restricted for sale
         to buyers 18 years of age or older. This includes the sale of G
         reloadable motors.
    C. DOT Shipping Restrictions:
       * Most single use rockets motors with less than 62.5 grams of
         propellant are now classified as UN 1.4s and can be shipped via
         UPS (with a HAZMAT fee) or regular parcel post.
       * Most reloadable rocket motor fuel grains weighing less than 62.5
         grams each are now classified as 'flammable solids' and may be
         shipped via UPS (with HAZMAT fee) or regular parcel post.
       * The UPS HAZMAT fee is now $10
       * Any single use rocket motor containing more than 62.5 grams of fuel,
         and any reloadable motor fuel grain weighing more than 62.5 grams
         are classified as UN 1.3c, or Class B, explosives.  These motors and
         reload grains may be shipped ONLY via Federal Express to certain
         designated shipping points.
       * Aerotech has announced it has received an exemption for single use
         motors up to K class and reload grains for at least L, and
