There is also an article by Trip Barber in some old issue of AmSpac or Model

Subject: Tracking a rocket with "RADAR"
Date: 20 Aug 92 21:45:58 GMT
Organization: Lehigh University

I've recently been working on a system that would let me track a high alttiude
rocket with "radar". Actually, it's not radar. But this is what I do. I bought
a 10mW 10.525Ghz transmitter from a company, and I took a radar detector and
placed it in the center of a 21" diam. microwave dish (I picked up 8 of them at
a junkyard). The transmitter sets off a radar detector as far as 100 meters
away, and the dish should give a gain of around 35dB. The half power beam
width would be near 3 degrees, which means theoretically, that the rocket's
elevation could be tracked to within 3 degrees. You could use the setup
manually, and just listen to when the beeps from the radar detector get the
loudest, or watch the display if it has one. Right now, I'm trying to put
together a servo control system which would automatically track the rocket,
but it's a little tricky.
Another thought I had was to get a VCO in the 10Ghz range and tune it to the
frequency of the rocket's transmitter. You can do this by taking the
transmitter signal and mixing it with the VCO and adjust the VCO until the
output of the mixer is at a minimum. Now, when the rocket is launched you can
measure the frequency shift, and you can calculate velocity, since you know
what the frequency for zero velocity is.
If anyone has any monkey wrenches they'd like to throw in, please feel free.

The name address of the person selling rocket tubes is:

Lou Scavone
41312 Memphis Drive
Sterling Heights, Michigan

(313)739-3058

He has the BT-55 (approx. 1 1/4" o.d.) and two sizes of smaller
tube - approx 3/4" and 7/8" o.d. (we just call them "1/2-A bladder
compartment tubes" - I'd have to check my Estes catalog to find out
what BT size they are). All are 18" long, and he says they are genu-
ine Estes.

At meets he was selling them for 50 cents each or $5 a dozen. 

Now here is the bad news. He said for mailorder he'd rather not
deal in onesies twosies, since the shipping would be prohibitive. 
He'd rather you ordered by the dozen, or for the budding entepre-
nuer he'd sell a hundred for about $30. (If one of you won't do 
this maybe I will). I suppose the idea is that you could then take 
them to NARAM and sell em for a buck apiece. 

Give him a call. His real calling is making Control-Line combat
kits - he makes some really nice ones. Did pretty well in the 
Chicago contest too!

I asked the same question at the beginning after a lapse of six months.

You guessed correctly; other than a spate of discussion, nothing really came
of it.  Too much cost, too small total impulses, and problems with the total
thrust to drag ratios as discussed elsewhere make this impractical for all
intents and purposes.  A pity.

Subject: Reloads Shippin Again - RMS32 - Phoenix
Organization: AT&T
Date: Fri, 21 Aug 1992 22:37:09 GMT



I got some e-mail from George Gassaway yesterday in which he said that
there had been a change in status regarding reloads of F size and below,
and now they ARE shipping again.  However, since G reloads are in a 
twilight zone (due to CPSC situation, I assume - Kevin), they are not
being shipped.  Anyone else confirm this?

On a (sort of) related note, I understand that George had a rather 
spectacular flight with his Orbiter at NARAM-34 using the RC RMS-32 
system. Did anyone see it fly?  I heard he thermaled it for 3 minutes.  
I'm curious about it.  It sounds like a parasite shuttle, but I've never
seen it.  BTW, I also heard he won G-RG by a wide margin; 19 minutes
for two flights (F10/D12-airstart and F10/F10-airstart) flying a
Bob Parks (of Phoenix fame)  design Raven 7.

If anyone attended and feels energetic enough to post a report, 
I'd read it! <G>

BTW, I've been flying a Phoenix for the past 3 weeks (almost daily).
Nice airplane.  As usual, I'm too cheap to buy many reloads so I've
been using a hi-start to build stick time.  If you are interested
in the Phoenix, but are concerned about spending bunches of money
to become proficient at flying it, a hi-start is the way to go!
I get about 300 feet altitude for $0.00 per flight.  My rocket-powered
flights have been limited to F13s, so far.  It's been very predictable 
on the hi-start and with the rocket motor.  I plan on using some of the 
hotter reloads this weekend.  I'll post some of my impressions.

What happened with these altitude busting 50,000ft N-N rockets that were
supposed to break records.
Did I miss them (wrong day/not paying attention)?
The best I heard about/saw was one that was tracked at 24,600ft
which got close, but didn't break the record.

I'd also like to hear more about what happened on Monday at BALLS
(had to go to work monday morning)
How high did this 40' 1000lb B.A.L.L.S. go, did it do better than the
1:1 Patriot on Saturday? 

Is anyone planning on doing some sort of summary?
I'd like to hear some highlights on who got big altitudes

Not being a prolific author, I can only relay the comments of some one who is.

Peter Alway has purposely NOT submitted articles to AMSPAM because of the

Bundick's NAR trustee meeting, and HUVARS has raised the issue in the 'needs

    Central Illinois Aerospace, an NAR section based in Champaign, Illinois, is
holding a high power rocket launch on Sunday, August 30.  An FAA waiver for
5000' MSL (~4200' AGL) has been acquired.  The waiver will be in effect from
1:00 p.m. to 6:00 p.m. Sunday afternoon.  The launch site will be at Chanute
Air Force Base in Rantoul, IL.  This will be a general sport launch and most
of the rockets launched will be smaller model rockets.  We do have a few
members with larger rockets which require a waiver.

    If the weather cooperates it should be a great day, so if you are in the
area feel free to come on by, there will be 8 pads and no waiting.

Aerotech now makes an 18mm reloadable casing.  I don't remember if they
make any "B" size reloads for it, but they certainly make coreburners in
other sizes.  

On one hand, you will never recover the cost of the casing in this size,
even assuming you don't manage to spit the casing and lose it.  Estes black
powder motors are too cheap in this size. On the other hand, if you love
this engine type and size that much to pay the price, then call and ask
Aerotech, by all means.

Slander and calumny.  Yes, the NAR is helping work reloads through DOT.
No, the person who initiated the CSFM confiscation of reloads is not now
nor has even been a NAR officer.  And what he did was IMO the right thing.
AeroTech had no business shipping reloads into the state and selling them
illegally, without the necessary certifications.  The CSFM certification
program is incredibly loose, and if AT had ASKED for the certifications,
they probably would have gotten them without a second thought.  Instead,
they shipped reloads into California under the lame excuse of "but they're 
not model rocket engines so they don't need the seal."  ALL pyrotechnic
devices in CA need the seal.

DOT is really not pissed about reloads, but about the way AT has been
shipping them.  They are about to swing the hammer down on AT, and the
hobby is just going to get caught in the downdraft.

As much as I disapprove of Barry Tunick's way of doing things, I have 
to admit he's right on the money when he says that when a manufacturer
starts trying to do end-runs around the regulatory agencies, the government
will damn near stamp out the hobby as a side-effect of its reaction.

What you want to do is get your hands on a reinforced cutting wheel
like the House of Balsa Tuf-Grind. The Dremel ones tend to shatter and 
throw pieces at high speed. If you use them harden them with thin 
superglue.

For working with foam NEVER use regular superglue!!!!

It melts foam. Use the new UFO odorless superglue. It doesn't attack
foam. For most foam gluing I use aliphatic resin (i.e. Elmer's). 

If you have a chunk of foam missing repplace it with a block of foam 
which you can then carve and sand to shape.

(How do I know all this? Theres something about building 80-90 foam
winged airplanes over the last few years... 8-)  )

You probably mean MAXUS. The MAXUS rocket is used by ESA and its membership
states for e.g. micro gravity research. The MAXUS rocket is the newest
version of the older Texus and Maser rockets, I believe. I think that
MBB is the main contractor in building these souding rockets.

In "micro gravity news from Esa" (june '92) the editor writes:
" The Maxus-1 reflight, originally scheduled for May 1992 has been postponed
  to early november 1992 due to the problems Thiokol (US) is having with the
  manufacture of the harness for the nozzle actuator system"
