Standoffs/whiskers help the kite hold it's shape. Depending on the
kite, whiskers can help a great deal. Many kites won't fly without the
whiskers installed.

Generally speaking, whiskers will cause a kite to turn more sharply
and more quickly. A kite with whiskers near the edge of the window
will be much more controllable, especially in light wind.

I've been experimenting with multiple whiskers per side on stunt
kites. Adding a second whisker about 18 inches in from the wingtip
will often increase the turning response on a kite. Sometimes the
addition doesn't do anything to the performance.

The obvious answer is check this group's FAQ it lists lots of places
which sell kites mail-order.

Personally I've been a customer of Adventures Kites, 29 Hemlock Trail,
Sandy Hook, CT 06482 (203 426 9786, fax 203 270 8250) for a couple of

his discounted prices.

A Satisfied Customer,

Even will all the high-tech stuff that can be found on the kite field,
and the demands and trials of competitive flying, I still find kites
and flying a simple pleasure.

There is nothing quite like a gentle breeze at my back and a firm tug
on the line to make the daily tensions dissolve away.

When I take a new kite onto the field to try it out, it's just like
when I was a boy. I'm excited and I'm nervous. I wonder how well the
kite will fly. And when it does rise into the air, I feel a great deal
of joy, whether it flies well or not, it doesn't matter.

It's magic.

Thank you all for making kites more fun and more exciting. I look
forward to the New Year with much anticipation and excitement.

May the New Year bring long days of gentle breezes and magic in the
air.

I've done it before, with some success.  What you need is a kite with
a lot of lifting power and stability, like an airfoil kite, and a
small camera with a self-timer.  Having a lot of wind doesn't hurt
either.

Here's what I used to do.  I'd make a little harness out of string for
my Olympus XA-2, and tie this to the bottom of the kite.  Then I'd pay
out 100-200 feet of string, and with the kite downwind, set the
self-timer, have a friend hold the kite straight, and then start
running with the kite.  It would almost always get up to full height
before the self-timer would go off.  Unfortunately, the pictures I got
back were inevitably blurry; the kite shakes a lot, and the camera's
shutter speed probably wasn't all that great.  The best picture I was
looking back down the string towards me.

I'm somewhat bigger than average (parachutes are sized for the jumper)
and my parachute is 210 sq ft (PD-210). The canopy I jumped as a student

Unfortunately, I'm of no use when it comes to techniques, cameras, etc.
However, I would like to relate that some of the most interesting aerial
photos I've seen were taken from a camera attached to a stack of Revolutions!
The camera was of professional caliber and had the ability to shoot a series
of pictures at a pre-determined rate.  The flyer just maneuvered the Revs
and hoped to get good pictures.  This is not a _great_ method because most
variables are left to chance.  The pictures that were worth saving, though,
were incredible.

Generally speaking, the Rev I fits your requirements better than the II.
The Rev I is slower, more precise, and flies in less wind.  Skill level
is probably irrelevant; I'm not convinced that one is particularly harder
to learn on than the other, though the Rev II might be a bit more challenging
given its speed.

Basically, though, once you can fly a Rev, either kite will do accurate starts
and stops, fly backwards, and so forth.  Personally, I think the Rev II is
_much_ more fun and better suited to basic pleasure-flying.  For competition,
the Rev I is the way to go in precision, and many folks fly it in ballet
as well.  While the Rev I is definitely _more_ precise and easier to control
because of its speed, don't get the idea that you can't do any sort of 
"target practice" with a Rev II.  I have no trouble landing on specific
spots (markers, flag poles, friends' backs, etc.) with my IIs.

For true ultra-light performance, you'd need Rev's ultralight kit for the 
Rev I.  Basically it gives you everything but the sail--new endcaps 'n bungees,
long-throw handles, and a spectra bridle.  And the kit works quite well.
I don't know if it's possible to buy a Rev I already tricked out in the
ultralight kit, or if you have to buy the stock Rev I and then buy the
ultralight kit in addition.

I realize this is sort of a wishy-washy answer.  The basics are, though,
that the I will fly in less wind, but it's still not an ultralight without
a new frame; the I is more precise, but for many people the extra level of 
precision is only necessary in competition; one is not necessarily 
easier to learn on than the other.  Because of all this, your decision
may very well boil down to a question of price.

Sorry, my instructions were poor. As you noticed from the subject
we are just seeking a proper way to submit plans. There are things
of concern: mail/news systems does not (yet) support graphic
file formats, the other is space.

The tools you need, are available on UNIX environment. some of
them in PC/DOS environment, too. Step by step:

1. uudecode is used to convert the character representation
   of a binary file to a binary file. It's like converting
   a hex dump back. (uudecode is available for DOS).

2. uncompress will unpack the binary file to it's original
   extent. compression was done to save space and bandwidth.
   I don't have uncompress for DOS, I don't know if it exist.
   The problem is that *.zip *.lzh *.zoo etc.. are not common
   in UNIX world.

3. tar is an archiver from UNIX world (available for DOS,too).
   it will collect many files to one "archive".

4. In this stage there should be two postscript files. In DOS
   environment you need Ghostscript to view and print,
   unless you have a postscript printer to do it.
   Ghostscript will support some dot matrix printers and
   it's free. Look for V2.52 or newer.

Steps 1,2 and 3 can be avoided by POSTing POSTscript,
it just takes some more space. Posting of GIF-files
needs at least the uuencoding, compression is useless,
because GIF's are pretty compact already. But, reasonable
sized GIF-files would reproduce only a fax-quality printouts,
that's why I suggest postscipt, whenever it is available.

John, I will mail the two postscript files to you,  get the
Ghostscript somewhere, it's very useful.

After writing that, I looked around in (on?) the local mirror
of SIMTEL20. I found a DOS version of UNIX compress in
directory compress (!). The file names are comp430?.zip.

So, all the bits and pices (uudecode, uncompress, tar and
ghostscipt are available for DOS, too. And they are free.
(I have not tried it yet).

Did anybody try to slow down commercial ethernet boards for the
IBMPC (e.g. 3Com, WD, Novell...) in order to send data at speeds
between (say) 500kbit/s and 2Mbit/s ? This way it should be easier than with
10Mb ethernet to send the data across a radio/IR link. The advantages
are:
- faster than RS232 ports;
- PC ethernet boards are pretty cheap nowadays;
- Ethernet boards are packet oriented rather than character
  oriented, so they won't kill your PC for processing interrupts.

If memory serves, some Ethernet controllers (82586, WD8390 ?) have
separate clocks for the controllers and TX shift register; other
controllers might be similar. The only thing I don't know is how slow
the TX clock can go. Apart from this, the patch should be trivial and
reversible.

	Any information appreciated.

The original concern of this thread was that the writer felt one
might be tainted or morally compromised by using a device for
recreational purposes that had its technological origin in weapons
research.  I don't propose to debate that topic in this arena, i.e.,
wether or not such reaearch is justifiable or not, etc., etc.  I
would like to argue, however, that such a debate is somewhat
contrived since it is nearly impossible to participate in any
backcountry activity (or nearly any other activity!) without the use
of some technology developed to adress a military need.  Perhaps the
the most pervasive of all is Nylon (aka Perlon) which was developed
as a sustitute for silk and other natual fibers in WWI.

	Just about any technology can be perveted in ways that aren't nice.
Your comptuer can be used to send harassing messages for example.  A nasty
violent person could create financial ruin if they tapped into the right
computers.  (See the movie "Sneakers" for some idea of this.  While
it had a few errors, it was interesting.  And no, I can't say anything
else about the earthquake in Manaugua.)

	As for using a GPS in Tienanmen Square, I highly doubt it.
The "government" KNEW where the square ws, they simply had to start shooting.
Keep in mind, a GPS can tell the you wher YOU are, not where someone else
is.  It's a receiver, not a transceiver or transmitter.  (Though those 
functions CAN be built in.)
