Hi

I can't say anything about the purely R/C magazines; I avoid them 
like the plague since I don't fly R/C. (Wait a sec.. R/C Report is
VERY good.. and cheap!)

I get Model Aviation with my AMA membership and its great value
for the money. They have at least one C/L design, one FF design and
one (sometimes more) R/C design every month. Also good columns, ads,
and competition coverage. I also find small, useful ads in there
for stuff like hardware and wood. Besides model aviation articles
you also find articles on full size airplanes, museums, etc. Its
also the place to keep up on AMA politics if you like such stuff.

I buy 2 magazines off the rack every month (I WANT my local drug-
store to keep carrying them... all the more exposure for the hobby).
These are Flying Models and Model Builder. FM has a Combat column 
every month, and a slew of others. Both magazines have coverage of
the non-R/C side of modelling.. peanut scale, indoor flying, C/L
aerobatics..you name it. I don't only read the stuff pertaining to 
my little corner of the hobby.. I find soaring articles fascinating,
ditto for ducted fans, helicopters and model boats. I've learned a 
lot from reading these. (Can't stand car articles though... ewwww...
MB used to have a car column).

Basically these magazines appeal to me as being somewhat more builder
-designer oriented as opposed to golly-gee-whiz-ARF-flyer-buy-the-
latest-fiberglass-creation-here oriented (which is probably why I'd 
never get into cars).

Except that epoxy generates heat as it cures, and a big "blob" generates more
than a little one.  I've had the left-over in a paper cup go completely solid
and "dry" while the thin small joint was still liquid (or at least "jelly".

The best book IMHO is Paul Tradelius's book, available through Model
Airplane News.  The book is not a concatenation of articles, as is Ray's
book, and it was much easier for me to understand when I was getting
started.

With Ray's book, I sometimes felt that RC heli's were akin to brain surgery
in difficulty.  Reading Ray's book, I was overwhelmed with building details
that are really only appropriate for advanced flyers.  On the other hand
Paul's book made the whole thing seem much more understandable and accessible.

  Do you find the 4 strokes to be as easy to operate?  I have seen many 4

    What is the best track materials (ex. clay, sand)?

The best indoor track in this area is Hobby Haven in Livermore.  It
seems to be composed of clay, sand, and topsoil.  The track is
rototilled, then compacted by rolling, then watered.  This gives a
smooth surface that does not dent too easily when turn marshalls walk
on it.  The groove on this track is clay-like -- has very little loose
material on it.  Cut "X" patterns work best unless the track dries
way out, at which time mini-pins appear.  The track is never watered
once racing starts.

The owner really works hard to keep this track in shape.  For a club,
I wonder if you might not be better off building a carpet track with
some added obstacles (carpeted bumps and jumps) to make it more like
off-road.  (You could remove the obstacles for on-road races.)  Track
maintenance would be very low.  Tire costs would be higher (foam tires),
and you might break more suspension parts, but these costs would be
borne by the individual racer.  My sense is that many clubs fail because
people won't volunteer to do the track maintenance.

    What makes the best walls? (tires, boards, nothing)?

Hobby Haven has tried various materials and ended up using six-inch
diameter white PVC drain pipe, half-buried in the soil.  The white
color is very visible.  The pipe is strong, so it stands up to turn
marshalls.  The inside of a sweeping turn is defined by an earthen
berm (whitened with diatomaceous earth) rather than pipe.  The outside
of turns is defined only to the extent of preventing cars from cutting
the track.

Flexible ribbed drain pipe is a very poor choice, because it "grabs"
your car on the slightest touch.  You get lots of popped steering
linkages with this material.

A local indoor dirt oval track uses a flat plastic material about four
inches high for the inside of the oval.  Short lengths of 3/4" PVC
pipe are screwed to this every four feet.  Short rebars are driven
into the ground, and the PVC pipe slips over.  This system is easy
on the cars (the flat plastic material "gives" except where it is
anchored) and keeps cars on track better than six-inch PVC pipe, but
I don't like having bits of rebar sticking out of the ground.

     What should the width of the track be (4 feet)?

Eight feet is a minimum for 1/10 off-road, and is marginal for trucks.
Going narrower will lead to more frequent and harder crashes.  I think
the ROAR rule book calls for 10 feet.

You might send a note to ROAR and to NORRCA, they should be able to
help you.  Try your ROAR regional director, too -- he might know of
some other clubs in the area that would share expertise with you.

Good luck, and let us know how it works out.

Re: the effectiveness of slats - read last month in FLY PAST, I believe, where a 
museum collection lost a deHavilland in a stall accident because one of the auto
deployed slats had been disabled (bolted shut, I think they said!) because of excessive
wear in the meachanism. 

	Model Airplane News for 11/74 had a high wing cabin model (somewhat 
along the lines of a Piper Pacer, with the nose of a Fairchild 26, if 
that helps :-) called 'The STOL Machine'. The plan and article was an 
education on high lift devices, including slats. Flew with gas, as a 
single and twin, the fellow who did it used it as a real 'mule' to test 
a bunch of ideas chronicled in the article.

	The stats on the plane  are_
WS: 48.5"
L:   41"
Eng.: .19 - .35
	4 channel radio, recommended fot the 'intermedite builder'.

	The stats are from the 'MAN PLANS DIRECTORY' catalog. Plans are 
still available, #FSP11741, for $12.
	It has been awhile since I ordered some plans from MAN, but I think 
all the magazines send a copy of the magazine article with the plans ... 
don't they? At least the construction part ...

	BTW, if anyone happens to have a set of plans for 'The STOL Machine' 
laying around gathering dust, I'd be interested. I collect (among other 
things) plans. Budget is low, mainly due to my currently returning to R/C 
('Ok, electric power sounds great! But where do I wind the rubber band 
for the escapement?') and, since Disney's 'Rocketeer' and Oshkosh last 
year, a mania for anything Gee Bee ... 

	Which reminds me ... if you happen to have any old plans for Gee Bee's
 laying around gathering dust ... :-)


P.S.  MAN PLANS offers the Crane plans, too. "Andy Lennon's impressive 
STOL design utilizes flaps, leading edge slats, spoliers and a 
variable-pitch propeller." Plan # is FSP04831, $19. AND the follow-on 
Gull Sport, "The near-hover capabilities of this desing by aerodynamics 
expert Andy Lennon makes it perfect for STOL experiments.", #FSP07842, 
$19.50. Note the paln # incorporates the date of the magazine the 
construction article appears in (07842 is 07/1984, the 2nd plan in 
that issue).


 Which reminds me ... if you happen to have any old plans for the Crane 
or Gull Sport laying .... :-))))

Thats kind of a low blow.  Harry attends and participates in his club's
monthly launches out in the desert, which have permanent FAA waivers, and
at which people fly all kinds of rockets on all kinds of systems.  
Furthermore, as head of the NFPA Committee, the people he has working
with him represent not only the major model and HP rocket manufacturers,
but pyrotechnics experts from factory to concert hall to film studio.
I doubt that anything in modern igniter technology has escaped his
notice.

You're right.  Launch it fully loaded and you will probably never see it again.
I think I actually got one back that I launched with this motor combination
but it was completely by accident.  I lost sight of it shortly after third
stage ignition.  It just happened to come down close enough to where I was
that I caught sight of it.  I have added an extra 18" body tube to the upper
stage of mine to try to make it more visible.  Its also painted with some
rather garish florescent colors.

Newsgroups: rec.models.rockets


Yesterday, I was in a park close to home when I saw a guy with a rather
LARGE rocket that he was about to launch.  I didn't ask any questions,
but now my curiosity is getting the most of me.

I was never into this hobby myself, but when I was younger, my brother
used to launch rockets of the "Estes" type.  Well the rocket I saw
yesterday was HUGE.  I'd say it was about three feet tall and the decal
on it said "initiator" or something like that (I'm assuming that is the
brand, or something).  I guess the motors required to launch such a
beast must be more powerful than the "estes" type.  Where do you buy
these things?  Do you need a special permit to buy the motors (in
California)?  How much are these types of kits?  Motors?  Are there any
clubs in the San Francisco Bay Area that use these types of rockets?

Thanks in advance!!

I want to thank CD for clearing up another of life's great mysteries:  why do
I have 2 Quest catalogs with totally different kits?  The kits in the hobby
stores are described in Quest's OTHER catalog (which DOESN'T have any prices).

Some of these kits are:

Kit Name     Skill  Size             Comments
Sprint         1    20mm x 36.8cm    Your standard high-performance streamer kit
Falcon         1    35mm x 60.6cm    Nice looking B/C sport bird
Evader         2    25mm x 41.6cm    Cruise missle look
Navaho AGM     3    25mm x 51.4cm    2 stage, air-to-ground missle styling
Antari         1    25mm x 33cm      Similar to Estes Alpha
Astra 1        1    20mm x 33cm      A power only, streamer recover
Aurora         3    25mm x 38.1 cm   'Stealth spy plane'.  A 1" dia. booster
                                      with a cute little parasite glider; the
                                      glider reminds me of the old Orbital 
                                      Transport glider.  I've seen this one 
                                      fly.  It's very nice.
Apollo         2    30mm x 68.2cm    A long sport bird with 3 body diameters.
Pip Squeak     1    20mm x 18.4cm    A very small streamer model; est 1800 ft
                                      on C6-7
Intruder       3    25mm x 48.9cm    Similar to the old Ester Orbital 
                                      Interceptor (was that its name?); a NICE
                                      looking kit!
Tracer         1    25mm x 38.1cm    Plastic fins and nose cone beginner kit
Nike-X         2    35mm x 61.6cm    Surface to air missle styling; 2 body
                                      diameters

One interesting point is that Quest kits all use Kevlar shock lines instead
of any type of elastic.

           In the summer I teach a rocket into science class
for gifted 7th and 8th graders.  Each session is two weeks
long.  This year I'm looking to change things a little bit.  I
want to put more "hands-on" activities around rocketry into the
course.  Our big projects have been the dependance of altitude
on estimated drag coefficients, rocket mass, rocket design and
finish. We make, launch, and triangulate different rocket
designs and look at graphical representations of their data.
Earlier this spring I asked this group about making recovery
wadding.  If I can think of a safe way of doing this, I might
devise a small unit on recovery wadding manufacture.  In the
past I have alos done labs where the students figure out what
effects a parachute's rate of descent. Do any of you have any
other ideas?  Be as specific as you can -It helps me :)
