  INTRODUCTION TO REC.MODELS.ROCKETS AND THIS FAQ

  Rec.models.rockets (r.m.r) is a Usenet newsgroup oriented towards
  discussions and topics related to non-professional rocketry of all types.
  All questions, comments, and ongoing discussions related to non-professional
  rocketry are welcome.

  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.
  However, 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 regularly posted.  The entire FAQ will make its appearance on
  r.m.r. from time to time, and as some frequently asked questions start
  appearing in great numbers.
    The entire FAQ is available on the web, and by anonymous FTP at the
  rec.models.rockets archive (see addresses elsewhere).
    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!!!  All 16 Sections of it!!!

         another kit or two before tackling a scratch scale project.
7.5   O.K., I've done all my research, collected all the data I can.
         I've even built a couple of scale kits a a warm up. Now I'm ready

       obtained?
10.9   Where do I find out the proper way to use HPR rockets and motors?  I'm
           familiar with the NAR Model Rocketry Sporting Code.  Is there an HPR
            equivalent?

11.3   Custom Decals for High Power Rockets
11.4   I've had several rocket body tubes ruined by the shock cord tearing
       into the body tube at ejection and making long slits.  How can I
        prevent this?
11.5   Estes 'toilet paper' recovery wadding strikes me as a bit wrong for HPR
       rockets.  What are some alternatives?
11.6   What are the differences between the various HPR body tube materials
        used by the 'major' HPR manufacturers?

       positive retention system?

       them in? What do I use for a motor block and where should I put it?


### PART 12: IGNITION AND LAUNCH SYSTEM TIPS

12.3   I've heard that Copperhead igniters are 'unreliable' for igniting HPR
         motors. Is that true?
12.4   Do you have any specific suggestions or tips for an ignition power
        sources? Can I use my old Estes ignition system with composite models?
12.5   WARNING:  Be very careful using any ignition system with 'flashbulb' or
          electric match type igniters.
12.6   The ignition of rockets by other than electrical means is banned by both
         the NAR and Tripoli safety codes and should not be used.
12.7   What is thermalite fuse and how is it involved in igniting rocket motors?
12.8   How do you ignite second stage composite motors?  Can I use a black
        powder booster for the first stage to ignite the second (as I do
        with multi-state A-D rockets)?
12.9   What is 'flash in the pan' ignition and for what is it useful in rocketry?
12.10  I would like to perfect a method for reliable ignition of clustered multi-
        stage rockets. Any suggestions or tips?
12.11  How do I cluster rocket motors?  When igniting a cluster of rocket
        motors, should the igniters be wired in parallel or in series? Why?
12.12  I am new to rocketry.  I was wondering whether anyone has tried
        using waterproof wicks instead of igniters to ignite a rocket engine.
12.13  The alligator clips on my launch system have worn out. What should I
        use to replace them?
