Christopher Pine - 23 Apr 2004 18:38 GMT
I would like to start a new post based on a post made by a "Beatle man" who
claims this hobby is dead or dieing. While I respect the mans( I assume it
to be a male no offense if otherwise) right to his opinion. He also said it
was boring and too expensive and chooses another hobby to occupy his time..
That's fine to each his own.
I personally do not care if it is dieing other than I enjoy doing it and
would like to continue. Regulation is necessary unfortunately and I am all
for reasonable controls and regulations. Reasonable is in the eye of the
beholder I guess. The Oklahoma bombings were done with fertilizer yet they
did not make all fertilizers of thsitype illegal... And outlawing all high
power or otherwise rocket motors is just as unreasonable. I think there will
be compromise and workable solutions will and have thus far been reached.
Kind of brings me to the question that some ask WHY do you do model
rocketry... well I enjoy it! That's why... am I trying to win a Nobel prize
or make some great scientific discovery... no just having fun, myself and my
children..
Maybe it is a dieing hobby but not for me I still pursue it regularly and
enjoy it.

Get off rmr and go fly rockets.

Is this hobby dying?

Not from my perspective.

Popularity of an activity ebbs and flows with time - just look at slot cars
for an example of that. Slot car racing has 'died' at least twice or three
times in my lifetime. So has bowling, for that matter.

So long as the products continue to be available in any way, I'll still be
involved.

Why?

Several reasons. First, it's been my major hobby activity for 38/48's of my
life. I can't imagine all the ways in which my life would have been poorer
without model rocketry, including:

- Two junior-high division regional science fair wins.
- A tremendous experience at one of the biggest NARAMs of all time,
NARAM-15 in Columbus, Ohio (thanks again, Dr. Gregorek!)
- Friends I look forward to seeing every summer on the flying field,
whether at NARAM, regional meets, fun fly events, or at HPR events.
- A never ending challenge to improve my building and flying skills.
I don't know why, but it never gets old for me.

First off, it's not dying, not by a long shot. Under attack but it's not
dead.

Most people on rmr are just confused. Every time I ask someone here what the

Beatle Man - 24 Apr 2004 04:27 GMT
Hello Christopher,

Well a scan of the replies does not surprise ... after all this is a
BIASED
group :)

If you asked the AVERAGE man/woman on the street ... they would not
know nor care about model rockets ... we do.  Yes WE ... there boaring
to fly, but collecting and reselling for cash is interesting ... guess
that is why the majority of sellers at Barbie Doll shows are male
sellers ... its the money ...

Look the readers and posters here are still going to do the hobby till
they are either cremated or lowered into the ground ... but who will
be flying rockets 75 years from now ... 150 ... there will probably be
AI robots kept as pets ... model rocketry was a FAD in the 60s and 70s
... for some of the nerds of today its a lifestyle ... but public
interest has all but dried up.

The same thing happens with any hobby/collectible ... take a look at
comics.
Growing up I spent my allowance at the comic stores.  X-Men were 15
cents a book.  Thor and Silver Surfer were about the same.  With $5.00
I could walk out of the store with an arm full of comics to read for
the remainder of the Saturday afternoon.

Now lets roll the clock forward 30 years ... Comics regularly sell for
$3 - $5 a book!  They are no longer being purchased by average ten
year olds in the scores ... the comic industry destroyed itself in the
mid 90s as did the sports card industry with high prices and volumes
of low quality products ... the same is true with rocketry ... made in
China ... plastic "idiot" kits [sic] that require 10 - 15 minutes of
time investment ... then its back to the Playstation or the XBOX or
Yu-Gi-Oh or Magic the Gathering ... or paint balls ... or Rap music
... or surfing the porn sites in the libraries ... or anyhing but
cuttting balsa, sanding, gluing, sealing wood and spirals, paint
primer ... painting ... dull/gloss coating ... joining up with a
couple dozen other young people your age to fly the lastest rocket
offfered from FSI, Centuri, AVI, pre Damon Estes ... its NOT the same
culture as it was 30 - 40 years ago.  Kids are NOT captivated with,
"God Speed John Glen", or "Lift-Off of Apollo 11 at 32 minutes past
the hour", or even, "Challenger Houston, your go at throttle up" ...
times change ... public interest changes ... hobby shops rarely carry
model rockets ... instead they carry R/C Cars ... believe me, a 16
year old today is more interested in a 1:10 scale HPI r/c car, then
they are running down to their local club house and trying to form a
NAR chapter.

One other thing that should be noted:

In the responces so far, no one has given numbers of membership
rosters.  Also, how much of  the hobby industry in dollars does model
rocketry account for when compared to 1966?  I am
99.99999999999999999999999999999999999999999999999 percent sure that
it is "back ground noise" today when compared to other hobby
interests.

Now, does that mean I am trying to get you to leave the hobby ... hell
no, I don't care what turns your crank ... I am just looking at things
objectively.  When I walk into hobby shops and toy stores and see
little to no model rockets, I have to go with what I see as opposed to
what I hope and feel ... thats all.

Model rockets are not the only hobbys taking hits ... greenware shops,
yes I do greenware, are closing and not being replaced ... young girls
no longer do crafts like before ... instead they dream of breast
enlargements so they can look like Brittney ... women no longer make
dresses so McCalls went out of business ... why because its cheaper
and far less hassle to let some Chinese
sweat shop in Harlem make the things for a fraaction of the costs to
make the dresses yourself ... rocketry is no diffferent ... why should
a 10 year old wait hours, days, for glue, and paint to cure, when they
can plop $10 - $20 down for a plastic ready made rocket, spend 10 min
installing the batteries, motor and igniter into it press the button
... ok done ... now back to Pokemon ... using drugs ... having sex ...
play station .. xbox ... rap ... its a different world from when you
were growing up in the "summer of love" back in 1967 ... kids DON'T
work with their hands like they used to ... no more spending hours of
cutting stringers and bulkheads for that tissue rubber plane being
built with your dad oon the kitchen table ... those days are over ...

I guess saying Model Rocketry is "DEAD" was a strech ... what I should
have said is that Model Rocket with regards to the public at large,
really is INSIGNIFICANT.  Oh, YOU the space minded hobbyist care, but
the public at large does not.  If it did, hobby shelves would be over
flowing with kits, rockets would be launched at NFL halftime shows as
was once done back in 1970, every science exhibit at school would have
some type of rocket theme ... it ain't happenen folks.

Here is a tip ... invest in Magic the Gathering ... very hot and
lucrative.  It first made its arrival back in 1993 and then died out
back in 1999 - 2000.  Now it is hotter than every and single cards can
sell for $500 - $700.

Now you might say, well model rocket interest flow and eb so just give
model rockets time ... the difference is that I can go down to my
local swap meet or card shop, and I will see 20 - 30 kids all sitting
down playing Magic at the sellers tables ... they are not bulding
Astron Alphas or the modern day equivalent ... and the nice thing is
that these kids in the next 20 or so years will be tomorrow's Magic
the Gathering collectors :)  Where are tomorrow's "ground swell" of
model rocket flyers and collectors?

So is Model Rocketry dead? ... I guess it depends on perspective ...
is model rocketry significant in today's culture? ... NO.

Yup.. the glory days are gone.. but I can say that about a lot of different
hobbies..

Just got back from launching at the local undeveloped park, Seems three of
us "rocketeers" got the same idea at the same time...   One group was three
generations just cracking open a starter set RTF.   Another group also had a
RTF set, but they have flown before... Then you have I and my family.. I'm a
BAR... All rockets were balsa, etc, etc, except for one Almost ready to fly
Shuttle Express.. Everyone had a good time.   One of the men stated.... "I
thought model rocket interest had all but vanished.. I'm surpised there are
three of us here!!!" ....  I told him, when the wind dies down and the skies
are blue, we come out of the woodwork.

I sure left a lasting impression when I launched my Maxi Honest John on a
F21 ... Up to pressure ... Baaammmmm!!!

This is just a park around the corner from where I live...

It's not dead..

JAO6469 - 24 Apr 2004 14:36 GMT
ok i admit i am what you all call a "lurker" but this post has some
significance. I am a horse shoer of 17 years. My clientele consists of people
from all walks of life. The other day one of my clients, whom is a science
teacher for 9-12th grade. I brought up the convo of Model Rocketry. She told me
that they have a new teacher coming in and that for the first time in the
school's history , there will be a Rocketry program. I then scriibeld so many
websites for her to pass along so that they could get the kids interested and
captivated, including ones that have some decent video to watch. Also gave them
the NAR and Estes sites so they can get the classes really involved. So you
see, here is a single person involving them selves for the future....the
kids...isnt that how the first astronauts started? Maybe 1 or 2 of a class of
30 will only take the interest, but at least its a start for a school that
never had a program in the past. Now do the math..if EVERY school got involved
in the hobby, then maybe, just maybe the numbers would grow and sales,
production, and strength in the industry would become even more greater. I
believe, we as parents, and i know there are many of us out there, should take
the time to get involved in the hobby with our kids. I know my 11 year old son
wants nothing more in his life other than rockets. And he is not happy with the
18 yr old age requirement for certification, but he is patient. At least i can
say he can assemble a HPR motor correctly. The smile he has when its completed
is amazing. Now THATS the satisfaction i like to see coming from the hobby.
Hopefully others do too.

On what economic basis can such a statement be made?  I fail to see

I respectifully disagree.  Estes still sells millions of rockets and

This is no different than it was 20 years ago.  Mass market outlet
don't make money on speciality products; they cater to a different
market.  Recognizing that economic fact does not relegate the hobby to
"dying" status.

I agree.

The absolute number of hobbyists in any given hobby isn't necessarily
relevent to whether or not a hobby is dying.  The real ratios I
believe should be examined are whether any given hobby has a sufficent
critcial mass to develop products and promote events.  If you look at
the past 10 years of the rocketry hobby, that critical mass has been
more than present.

I would obviously prefer that more people participated.  However, with
the numbers we have or are likely to reach, we have a sustaniable
hobby, IMHO.

Once we reached the moon, I've been hearing "the hobby is fading" since
1970. 34 years later, it's going very strong even with all we are dealing
with today. Consider the size, type of rockets, engines available and the
numbers of people belonging to the clubs and number of clubs since 1970,
then tell me the hobby is fading.

There may have been a few drop out since 911 and because of the ATF but for
the most part, I think the current environment has made the true rocketeers,
more determined than ever to build, fly and enjoy the hobby.

I beg to disgress but here in Canada the situation is the opposite.  
Because of Aerotech's motor supply problems and seeming inability to
deliver motors to Canada, people here have been dropping out of the
hobby like flies.

Our club here near montreal has gone from a peak of around 40 active
members to about 20 due to lack of motors, lack of insurance (CAR) which
means we're forced to seek more expensive alternatives (MAAC/Tripoli)
which has discouraged alot of folks here from flying.

The "bigger variety of motors" seems to be far for us up here in Canada.  
Our main supplies these days are CTI motors (Cesaroni), Hyperteks and
Estes.  No aerotech motors to be found anywhere.

I have tons of colleagues with 29mm and 24mm powered rockets that are
gathering dust because we just can't fly them and retrofiting them to
use 38mm is just a real big pain.

Hobby shops in Quebec carry fewer and fewer rocket kits.  Five years ago
you could walk into most hobby shops and find Estes and Aerotech kits
everywhere.  Nowadays, many have simply stopped carrying rocket kits at
all, and if they do have kits, it's mainly Estes RTF junk.

I don't think rocketry is going to die inasmuch as there's always going
to be a hardcore bunch of flyers who will do whatever it takes to get
motors and fly.  But the reality is that there's very little new blood
coming into the hobby here and the barrier to entry is getting higher
and higher which means to me, we're only going to see the hobby dwindle.

I don't know how it's going in other parts of Canada recently but my gut
feeling is that many rocket clubs have seen similar things happen.

The irony of it all is that it's probably EASIER to fly HPR than to fly
low-power now because more HPR motors are available (via CTI).  However
since the entry-level is sorely lacking, there's just no new flyers.

MHO.

I think what we're seeing right now is that there are issues affecting the
hobby on a regional basis. For you folks in the "Great White North", it's a
lack of AT motors. In the states, some areas have been hit hard by the ATF regs
(or vendors' interpretations of them), inability to get local storage, etc.
Meanwhile, in regions where local vendors and a good motor supply are
available, the hobby has been growing by leaps and bounds.

I think you're right Ray and I was only speaking about the U.S. At least in
the South, I think there is still some growth at least on lpr, which is
where most of us got our start.

On the contrary...
My son and I just took up the hobby and are finding it totally fun for us to
do!
We have made 4 flights to date, (in two days) - but I am finding issues with
the
Rocket motors... out of 6 motors, 2 have been duds.. or am I doing something
wrong???
If I am please reply!!

What do you mean by duds?  They didn't ignite, or something happened in
flight?

If they didn't ignite, 99 times out of 100 it's because the igniter was
inserted incorrectly, or the clips to the controller were too far
apart/shorted, or the battery was low, etc.

I did a launch with a bunch of kids a couple of weeks ago.  Out of > 500
engines, we had a couple of dozen fail to ignite.  In EVERY CASE, it was
either inserting or connecting the igniter incorrectly, and re-using the
engine with a new (properly installed and connected) igniter made it
work just fine.

Hard to say what might be the motor problem from just this info. I
assume these are Estes black powder motors. Most failures are external
electrical issues, not motor problems.

What do the igniters look like after a launch attempt on a "dud" motor?
Are they burned/melted in half? Are they melted at some point OTHER than
in the middle? Do they show any indication of being heated at all? Many
ignition failures are caused by shorts in the igniters and/or clips
outside of the motor or the igniters are not inserted all the way into
the motor and up against the propellant grain. Its easy to short the
igniter wires together if the plastic nozzle plug holding the igniter in
is not inserted properly. Make sure the silver colored igniter leads do
not touch each other. Also make sure the igniter leads and launch clips
do not touch the metal blast deflector, or other metal parts, and cause
a short across the launcher leads.

Test fire an igniter outside of a motor and ensure you get a prompt
ignition of the igniter and pyrogen (the black stuff on the igniter). If
the igniter does not fire almost instantly, replace the launcher batteries.

Peer down into the nozzle end of a "dud" motor with a flashlight. You
should see dark black propellant. Sometimes light gray nozzle clay will
be coating the propellant and preventing ignition.

A 33% failure rate is NOT typical of commercial BP motors.

What kind of motors are you using...and just for the record...out of
the well over 1000 rocket launches I've made in my lifetime, I don't
recall ever having a motor fail to operate.  I've had a few where I
had to use more than one igniter, but that's usually because you did
not install the igniter properly, or IT was defective.

I did have ONE rocket engine that for some reason had a "blow out" in
the side of the motor which burned through the wall of the motor and
through the body of my rocket as well, but I didn't know it until the
rocket landed.  I knew that it sure didn't fly very straight, but
didn't know why until I examined it.   But honestly, I don't think
I've ever had a motor to fail.
