Rec.Models.Rockets Frequently Asked Questions: PART 4 OF 14

BORN AGAIN ROCKETEERS
----------------------------------------------------------
4.1   What the heck is a 'Born Again Rocketeer'?

    A Born Again Rocketeer (BAR) is a person who started out in model 
    rocketry in their 'younger' days, dropped out of the hobby for some 
    number of years, and then came to their senses and got back into it. 
    BARs are noted for re-entering the hobby with extreme enthusiasm and 
    much deeper pockets than they had during their first encounter with 
    the hobby. Actually, the length of time spent away from the hobby is not as
    important as the extreme enthusiasm that BARs have when getting back into
    rocketry.  It's like, we have to make up for lost time or something.
    The editor of this FAQ is a BAR (and proud of it  :-). 
    
    Paul Wolaver <pwolaver@sybase.com> wrote this BAR observation:
      Be prepared for the BAR phenomenon.  Open your wallet.  Write off your
      weekends.  Set aside a room in your house to build rockets.
      Buy epoxy.
----------------------------------------------------------
4.2    I have been out of model rockets for many (i.e. <nn>+) years now.
          What been happening in the hobby over the past couple of decades?
          What's new? What's gone?

4.2.1    Who's Left, Who's Not & Who's New

    To sum it up...

    Gone:              Centuri/Enerjet
                       Rocket Development Corporation
                       Space Age Industries
                       MPC rocket kits
                       Coaster
                       'S' Series (short) 18mm motors
                       Competition Model Rockets
                       AVI motors

    Still here:        National Association of Rocketry (NAR)
                       Estes
                       Flight Systems
                       

    New:               High Power Rocketry, with *BIG* rockets
                       Tripoli Rocketry Association
                       MANY new companies
                       Composite rocket motors are commonplace
                       Reloadable solid rocket motors
                       Hybrid rocket motors
                       Phenolic and fiberglass rocket components
                       Electronic altimeters, flight computers,....
                       Much improved rocketry simulation software
                       And a whole lot more.....

    Basically, it's all pretty much the same, or totally different,
    depending on your interests.  Estes is still Estes.  Most of their kits
    are still the same materials, etc.  The trend for the last 10 years has
    been for Estes to sell simpler and simpler kits.  There are lots of
    plastic nose cones and fin units (already around when you were active
    before).  There are now kits with pre-slotted body tubes and plastic
    fins (as in the Estes E2X series).  Lot's of good stuff for beginners
    and kids.  Estes now makes engines in the 1/2A - D range, all black
    powder. Estes has some Large Model Rocket offerings ready, as well.
    Read below for details.

    Flight Systems (FSI), another motor and kit manufacturer that got its 
    start in the late 60's, was reported in 1995 to have ceased its 
    model rocketry operations. They have restarted production in 1996, and plan
    on being up to full production by 1997.

    Centuri, sadly, 'went away' in 1980.  Daemon Industries bought both Estes
    and Centuri in the 1970's.  They operated both companies as independent
    units for several years.  Finally, Centuri was dissolved and its products
    absorbed into Estes.  Every now and then an old Centuri kit surfaces
    under the Estes banner. An interesting piece of trivia is that the tax
    and incorporation laws were more favorable in Arizona (home of Centuri)
    than Colorado (home of Estes). So, Damon, on paper, had Centuri acquire
    Estes, even though it was Centuri's operations that were eventually shut
    down. Damon sold off Estes to a group of investors in the early 90's.

    Now for 'who is new'.  First, in model rocketry there is a new kid
    on the block: Quest.  This is Bill Stine, some ex-Centuri people
    and others.  They are a direct competitor to Estes.  They have a line
    of kits and engines (A-C).  Good quality.  Less expensive than Estes.  
    There are many other smaller companies making and selling model rocket
    kits.  See Part 02 of the FAQ for addresses.  Custom Rockets is another
    company with rocket kits similar to those offered by Estes and Quest.
    Custom offers quality paper tube/balsa finned kits in the A-D power
    range.

    Aerotech, LOC/Precision, Rocket R&D, Public Missiles, and North Coast
    Rocketry are some new names in the business.  These companies cater to both
    larger model rocket and high power rocket markets.  Estes bought manufacturing rights
    to all NCR products in 1995. Estes has announced a line of F/G rockets
    (based on NCR designs) to be released in the first quarter of 1996. Estes
    may also release a small line of F and G composite motors in 1996. A
    newer outfit, Rocket R&D, bought out THOY and another smaller HPR
    manufacturer, Cluster R.
    
    Aerotech manufactures both single-use and reloadable composite rocket
    motors ranging from C to M total impulse classes.  They also offer a few
    kits designed for E to G engines.

    A couple of outfits make kits using newer technology materials, including 
    phenolics, fiberglass, and composites.  These include Public Missiles (PML),
    Rocketman and Dynacom. Be prepared to pay more dollars for the more 
    advanced materials. A $60-75, 4" diameter, heavy paper tube based kit,
    such as manufactured by LOC, might cost $100-125 in a phenolic based
    kit, such as produced by PML. A Dynacom fiberglass kit of the same
    size might cost closer to $350.

    If you were into rocketry in the early 1980's then you probably remember
    AAA Model Aviation Fuels.  They're still here, with a line of HPR and
    Large Model Rocket kits.

    If you were into competing you might have been familiar with Competition
    Model Rockets (CMR).  They are now defunct but there are constant rumors
    of a rebirth 'sometime in the near future'.  Other companies have stepped
    in to fill the space left by the exit of CMR.  See the section
    'Competition' for some names and addresses.  Two notable new companies are
    Apogee Components and Qualified Competition Rockets. Apogee was started by
    long-time rocketeer Ed LaCroix. QCR was started by another long-time
    rocketeer, Keneth Brown. Ed has now joined the Aerotech team and 
    dropped most of his product line. A new company, Eclipse Components, is
    picking up most of the Apogee Components line, except for motors. Apogee
    will still be selling those. Pratt Hobbies has indicated that it will 
    pick up some of the old CMR product line, and has already made the CMR egg
    capsules available again.

    A lot of the 'neat' Estes kits of the 60's and 70's are no longer
    available.  However, Estes is bringing them back (one by one) in so-
    called, 'limited run collector series'.  The original 'Mars Snooper' and
    'Maxi Honest John' kits have been re-issued, so far, along with the 
    Star Trek and Star Wars kits.  More releases are supposed to be 
    forthcoming.  WARNING:  Be prepared to pay a much higher
    price for these re-released kits.  Remember that inflation has led to
    some items having much higher prices now than in the mid 60's and 70's.  No
    doubt Estes will take advantage of the demand for the re-released kits,
    as well, and charge an additional premium.

4.2.2   Changes in Motor Technology

    The big changes have come in motors.  Expendable composite fuel motors
    are now available in B-G range for model rockets. These motors
    use ammonium perchlorate for oxidizer and rubber as the fuel, similar to 
    the rocket boosters on the space shuttle, allowing them to pack two to 
    three times the power in the same space as a black powder motor. The B
    motors from Apogee are the same size as Estes mini-motors (13x45mm).  
    The C motors (also from Apogee) are 18x50mm, while the D motors are the same
    size as Estes A-C motors (18x70mm).  The D is a full D (rated at 20 
    Newton-seconds versus the Estes 24x70mm D of about 17 N-s).  E motors range 
    in size from 18x70mm to 29x124mm.  All of the motors give Estes kits an incredible
    ride, if the models hold together.  These kits require stronger construction 
    methods and materials than typical model rockets. Put an Aerotech D21 or E25 
    in your old Big Bertha at your own risk!!  You're likely to end up with a 
    model with no fins (i.e., a complete 'shred').

    Another new trend is 'reloadable' motor technology.  With reloadables
    you have a metal motor casing that you manually reload with solid fuel
    pellets, delay and ejection charge for each flight.  The casing is
    reusable.  Reloadable motors are available in everything from 18x70 mm
    (with B - E power), 24mm, (with D - F power), 29mm, 38mm, and much
    larger.  Again, you can get all the way up to 40,000+ Newton-seconds of
    total impulse.

    The latest technology to hit the High Power rocket scene is the hybrid 
    rocket motor. Hybrid motors use components from both liquid and solid
    ful rocket motors. Two companies have currently certified hybrid motors
    with Tripoli, Aerotech and Hypertek. The advantage of hybrid motors is
    that they use totally inert fuel grains, such as a cast polymer plastic
    or compressed paper pulp, which do not have any DOT or ATF restrictions.
    With both motors, nitrous oxide is used for the oxidizer. The NAR has not
    yet certified any hybrid motors, but is currently evaluating them.
    
4.2.3   Competition

    One notable difference between the time I left the hobby (late 1970s) and
    today is that competition rocketry is not as popular as it once was.  It
    used to be that one would see 30 or more people at an NAR regional, but
    today it sometimes seems like you are lucky if you get enough people to show
    up.  Because I got back in to the hobby to fly competition, I am concerned
    about the apparent loss of interest in competition rocketry.
    Still, competition is NOT dead, no way.  Yearly NARAMs are still held,
    and are well-attended.  About half of the NAR sections still host meets,
    or have members that fly competition.  The rest fly sport and/or high power
    rocketry only.

4.2.3   High Power Rocketry

    Now there is also HIGH power rocketry (HPR).  These are rockets with
    motors up to type O (with greater than 40,000 Newton seconds of impulse).
    There has been a lot of discussion about high power recently.  You have to
    be a member of either the NAR or Tripoli to fly rockets with H motors or
    above.  To fly with H or above both organizations require that you be
    'certified' by safely demonstrating a successful flight with a high power
    model in the presence of one or more 'qualified' members of the
    organization.  There is now a HPR safety code as well as the original
    model rocketry safety code.  There are expendable and reloadable
    (discussed below) HPR motors available.  They are increasingly
    expensive as the power goes up ( $13 for a G up to hundreds of dollars
    for a really big (O) motor).  High power rockets start where model
    rockets leave off (i.e., > 1500 grams).  High power models weighing
    more than 50 pounds are not uncommon. The record weight for a high 
    power flight is over 1000 pounds.

    Oh, yes, HPR requires a duly authorized, signed-in-blood (in triplicate,
    etc.) FAA waiver for each day you wish to fly.  It is ILLEGAL to fly
    high power rockets without a proper waiver. See section XXXXX for more
    information on FAA waivers.

    Depending on the type of motors you buy, use, and store, as well as where
    and how you buy them, you might need some additional, FEDERAL, permits
    for high power rocketry. More on this below, and a lot more in Part 1 of 
    this FAQ.

4.2.4   Electronics Advancements

    Advances in electronics technology have created many opportunities for
    new ideas in consumer rocketry.  Electronic ignition of upper stages of
    multi-staged rockets is now common.  Several altimeters more recording
    maximum altitude are available.  Electronic deployment of recovery
    devices, as well as deployment based on altitude, is now practical.
    The FAQ sections on High Power Rocketry and Payloads have more to say
    about this.  See Section XXXXX for addresses of some companies selling
    rocketry electronics.

4.2.5   Regulations, Regulations, Regulations

    There is some good news and some bad news concerning rules and
    regulations relating to consumer rocketry.  On the positive side, you
    can now buy up to G power motors in most states.  Also, some states, such
    as New Jersey, have recently relaxed restrictions on model rockets.
    There is a menacing down side as well, though.  California still has some
    of the most restrictive regulations in the country. The ATF and DOT have
    both become quite interested in high power rocketry and have begun 
    enforcing shipping and explosives regulations. Read the current
    regulatory summary in Part 1 of this FAQ.
----------------------------------------------------------
4.3   Are my old rocket kits worth anything today?

    With all of the BARs coming back into rocketry, many wanting to rebuild
    some of their favorite kits from their youths, models rockets have 
    become 'collectable'. In fact, the demand for some classic kits has 
    gotten quite high. The explosive growth of the internet has helped 
    fuel several recent 'class kit' auctions. Model rocket kits from the
    late 60's and early 70's can still be found, but be prepared to pay 
    quite a premium. It isn't unusual to see what was a $5 kit from the early
    70's going for $50 or more in an auction. Remember the 1/70 scale Estes
    Estes Saturn 1B? It cost $11 in 1970, $15 in 1977. If you bought one 
    today at a model rocket auction, it is doubtful that $200 would get it.
    How about the Maxi Brute Pershing 1A, which sold for $17 in 1977?
    That kit, in good condition, might bring over $150 today.
    
    So, all you BARs with old kits up in the attic might want to think
    twice before ripping open the boxes and finally building that 
    Orbital Transport you got on your 12th birthday.

    Opinions about the collectibility of old kits varies on r.m.r.  Some frown on collecting 
    kits, and feel the rocket should be built and flown for maximum enjoyment.  Some 
    would consider building the old kit a great loss.  Others take a middle road, and "clone" 
    the kit - produce a duplicate, and keep the original.  Still others create scaled-up versions 
    of old kits for HPR flying fun.  Regardless of what you do with it, old kits can be a lot 
    of fun, and there is even a magazine devoted to collecting old kits (see Part 2 of this FAQ 
    under books and magazines).
