My advice is for you to contact Sport Flyers' Association.  They WILL
cover your events.  AMA is no longer the only game in town, and if
their service is anal-retentive, go elsewhere.  Contact Doug Pratt
(76703.3041@compuserve.com) for more information.

Yes.  Several HUVARS members have flown various forms of cameras.  The
disposables have the same limitation and the Astrocam - one shot per flight and
little control over what is in the frame.  Speaking as an Astrocam owner, I
wouldn't buy another one.  You can fly a motorized 110 (rigged with an
inexpensive motor repeatedly trip the shutter) in a BT70 on 2 D's and shoot a
12-24 exposure roll of film.  Your chances of getting a good picture are much
higher.

Take a couple of pop sicle stick and make a see-saw.  Rubber band it to the
camera so one end is depressing the shutter release.  Tie the other end down to
free the shutter with a burn string or trip wire.  When the string is broken,
the camera takes a picture.

Wow LDRS was great Now I am so spoiled and have to go back and fly on east
coast fields Argh !!. A few corrections I think the last flight from pad 99
the N to K staged flight from J. H. Univ. may have broke the record. I heard
50,000 + . Also the Team Igorance Rocket was powered by a full O in the middle
with 4 L's etc ... The motor in middle would have been a weak P (was designed
by Chuck Mund) but had different prop. that made it fall in top O range. I was
happy since the timer I built the night before flew in it. Wow what a great
job those folks did. You had to see it to belive it.

  Oh yeah one more neat thing I saw was a launch of a LOC Bruiser using
37 (yes 15+15+7) Estes D12's!!  It used flashbulbs (37 of them too!) to
get them ignited.  The wiring looked like something out of a 1950's SF

  Anyway, most of use were pretty skeptical about the probablity of

The reasons behind the "miracle" of recovering a Mosquito include its size,
speed, and potential altitude.  As was mentioned here a few days ago, you
can't watch a Mosquito "take-off."  It just disappears.  If you're lucky  
(a small engine helps), you may catch sight of its smoke trail during the  
delay, or a puff as the engine ejects.  If you do manage to catch sight of
it again, your only hope is to avoid blinking until it is on the ground
and you've located a landmark near where it hit.

What amazes me most about the above mentioned dozen flights is that, being
young, I wanted my rockets to go HIGH.  So, after the first flight, those
were mostly using A10 motors.  In the end, I didn't actually lose the rocket;
its demise was that most noble end for a rocket -- an explosion.  Being young
and having less common sense than I do now, I had repainted it with a motor
in it.  Needless to say, this pretty well glued the motor in place, and the
ejection charge blew the thing to pieces.  I recovered a little curl of 
cardboard from the body tube.

Anymore, I seek low, slow-flying rockets that look neat (like Dragonship 7
and the Trident II) -- but that deserves a separate discussion.

The Astrocam was made by Estes for its rockets. It has been through several
iterations. I owned one about 26 years ago (my how time flies) and it used
circular film discs, one exposure per shot. The shutter was spring loaded, 
and a string was captured between the camera, which served as a nose cone
for the rocket, and the body tube. When the ejection charge fired and the
camera separated from the body tube, the string would be released and the
shutter on the camera would click. They later replaced the funny little
round film magazines with a 110 film pack.

>From my experience, a very low percentage of pictures were any good. That
is because:

1. The rocket hadn't heeled completely over and was pointing off somewhere
   other than down (this was probably my fault for not having a long enough
   time delay between the engine stopping and ejection charge firing).

2. The camera was bouncing on its bungee connection to the parachute, causing
   a blurry picture.

You needed a PERFECTLY timed ejection to get a good shot. It had to be long
enough to make sure the camera was pointing downward when it fired.

That's what I know - and it has darned little to do with R/C planes!

I have a Ricoh 35mm that I fly in a 3" rocket.  I won't take credit for finding
it, Bob Alway found it.  It a mid price Ricoh (about $105-115 on sale).  The
advantage of this camera is that it has a programable 'continuous' mode and a
remote shutter release jack.  Press the shutter release or short the remote
control cable and the camera takes pictures about 1-1.5 seconds apart depending
on film type, cassette size, and battery condition.  The remote connector is a
standard 1/16" phone plug.  All you need is a micro switch or pull-out-plug to
short the leads at first motion and the camera will happily take pictures until
the roll is finished and then rewind it into the cassette.

Howdy All,
	I seem to remember someone saying that the AstroCam was no 
longer being made. As I haven't checked recently I don't know. IF they
are no longer being offered, why? From the number of posts here that
kit would seem to be an immensly profitable seller. Or is it just us
netters that seem to like taking pictures at great altitudes? 
	On a related note - is there still (was there ever?) a kit
that took 8mm or Super 8 movies from within a trusty modroc? Has this
also disapeared? That would be a very interesting thing to view! 
	One more question for the experts...Whats up with G.Harry
Stine? Is he still involved in the field? I remember my own 
introduction to model rockets was through one of his Handbooks that
I found in the high school library when I was sixteen. I see that he
still has a column in 'Analog', is he still cranking out The Handbook
or has that been handed off to someone else? I remember it was a 
no-nonsense kind of thing which stressed saftey on every other page
with sentences like, '...if you like to make things blow up join the
Army and become a Demolitions Specialist'. Excellent advice actually.
That book was what convinced my parents I wasn't going to kill myself
or be arrested (they had this notion that a model rocket was some
kind of fireworks).
	Thanx all, sorry if this is a post filled with FAQs!

You'd rather bring your personal one-hour film developing lab out to the

CD's right. Tomm Aldrigde of SuperPower, Inc (our local AeroTech dealer),
myself, and a couple of other guys in our club did a couple of our own
experiments with two reloads Tomm donated. Neither of the two we fired
moved. NOT ONE INCH. They burned very bright, and in a shape that reminded
us of a Japanise fan. Also, it took Thermolite to get them going - a bic
would'nt do it.

Maybe.  They have a viodetape you can buy that shows video from an

Well, probably not, but perhaps he could have.  I dunno, I'm no pilot.

No, no, not really.  The popular wisdom among musicians was that solid
state amplifiers lacked the "warmth" and depth of tube-type amplifiers.
Similar to the modern "CD vs. vinyl" debate.  Especially on the amps
for low-side music such as basses or organ pedals.  Some ten years ago,
I went shopping for such an amp.  None of the solid state amps in the
same price range as the old Fender bass amp had any low end at all.

Has nothing to do with rockets.  I don't even know where to set the

Hey Will-

Perhaps you should call Bob Kaplow just <<one>> more time to suggest he
contract out the copying business to Kyle Shugrue at Rocketmen Videos.
Perhaps Bob can tell Kyle where to get the original to avoid one generation
loss from copying Bob's tape.  Plus, Kyle may have better equipment.
