Ross Jahnke's idea for the pee wee event sounds like a winner if we publicize 
it in the right places. We seem to preach to the choir a lot in this hobby, 
and never reach out and touch the vast unwashed out there. Or even the half 
vast ones for that matter.
One thing about the rules Ross proposed: The price of stock glo heads for the 
babe bee is twice what the whole engine used to sell for and are damn near 
unobtanium anyway. Better just leave the glo plug issue alone and allow 
anything that lights up the fire as the performance ain't all that good any 
way you run them. That eliminates an easy way to cheat.

Symposium Editions

NFFS is looking for two complete sets of Symposium editions.

One for the AMA Library.  These poor souls do not have a single 
Symposium edition in the Library!  Freeflight, you know.

The other as a portable reference for the current ( and future ) Editor 
to use, for inspiration, instruction, to instill
a sense of history, - get the idea...  The thought is to pass it on to 
successors, with additions.

In the receint past someone offered a complete set for sale, and it went 
for 300.00.  So the market has
set a price.  The AMA Library set could be a tax deductable donation, 
maybe.

Extended weather forecasts

Roger

In regard to recent EN comments about weather forecasts, AMA Headquarters
receives the most useful extended data for modelers I have ever seen.
Perfect for CD's and fliers at contests.  DTN (Data Transmission Network;
http://www.dtn.com/weather/), a satellite dish based service,offers an
apparently very accurate three day forecast which includes the following
data at three-hour intervals: temperature, wind direction, wind mph, dew pt,
rel humid, heat index, cloud cover and precipitation.  I checked a DTN
forecast prediction at a recent Muncie contest (weather data for
Indianapolis) and it proved to be 100% correct for the two days.
Predictions for change in wind direction were accurate and helpful.  In
addition to the above three-day data, the report page also provides a less
comprehensive 11-day forecast, including for the previous and current day
and nine advance days.

The DTN reports can be obtained easily at Muncie during week days but less
readily on weekends.  The trick is to pick up a report on Fridays before a
contest.

DTN offers a PC based service but it is costly.  There is apparently no way
for a flier to digitally access the data via AMA, which would be ideal if
workable and legal.  Steve Kaluf at AMA provided the info about DTN and
their wether services.

If any one can figure out how to easily access the DTN data, it would be of
great value to all fliers.

Re: rubber wire tap
===================

Dear Roger,

I am quoting from your last SCAT page..

<< From rubber tester #1 ....I wound consistently to 480 -485 turns.>>   

 Is this possible with a 35gm motor?    A 28strand 40gm motor could well give 
those figures but  if it was 35gms, I suspect it must have been 26 strands!   
I am mystified.   I seldom break F1B motors but I do wind 26 strands, 35gm 
motor to ca 100 in/oz and get similar turns to those quoted.

Whoever sent this piece, it all made very interesting reading.  I look 
forward to hearing more.

[Peter, in a number of the more recent batches of rubber there have been some
parts of the box where the rubber is very thin. I normally have a 28
strand motors [about 14.5 inches long]. However with this thin rubber the motor
come out longer and the rubber seems to have more stretch, so sometimes I have
had to go to 30 strands.  But I think the guy who makes the rubber
is named Murphy because a number of these motors are too long
when they have 28 strands and too short at 30. Life was simpler before
I tested by rubber and did not know any better.  Actually in reality I do not
think I know better but it is more complicated.

I think a number of people went to 26 strands just because AA did that
at Sazena, I know I'm not as good with rubber as he is so I did not do
that because I could not see any advantage ...

Also for whatever its worth I suspect that with the May 99 
rubber you would see at least 110 oz/in , probably 120. I probably
shred more motors than  you, anything to keep John Clapp happy.

Denver Trip Successfull!
========================

The VIOLENT T-storm and Great Flood of Vegas slowed my trip home 
yesterday, but my
trusty Honda Civic wagon did good and I found enuf high ground and 
shallow, flash-flooded,
rushing red "streams" to allow relatively safe passage. Interstate 15 
had flooded underpasses,
so I exited and did a lot of sidestreet travel with much backtracking to 
avoid deep water.
Finally, way south of town, I-15 could be entered, but you should have 
seen the debris left
in the path of rushing floodwaters!  Even saw a giant(20 ft) trash bin 
floating in the overflowing
drainage channel beside I-15! 

Well, I put last(most Vivid) things first, so now on to the earlier 
phases of my trip.
HOT(112f+, Wed 30 June) across the Mojave, including Vegas and on into 
Utah. 
The Virgin River, Zion Park and the Rockies in general were more 
enjoyable, scenic
and impressive than I recalled from 1948 visit!]

I drove directly to the flying field(leased jointly by Magnificent 
Mountain Men and SAM) just
after 1pm Friday. It was windy, but fliable with 90 degree air temp.
Pleasantly surprised to see Al Brush, John Pratt, Jerry McGlashen and 
Herb Sessums had
made the effort as well.
The Field: Quite a bit larger than Waegel Field, similar rolling-hilly 
cow pasturelands,but
more sloping and elevation changes and turbulence to contend with.  
Sure, the air is thinner,
but I found no trim changes to be necessary for my Nordics or my chuck 
gliders.
Thermals got stronger in the pm, taking 4 min + to land after dt at 
times.  It seemed to be
wisest to watch your bird land, take bearings, then go downwind to 
retrieve it, since you surely
never had a straight line travel path due to the gullys and general lay 
of the land.
As Ken Phair said, "The field is your main competitor, normally. You 
must percervere."
So when I won F1A (Pete McQuade and Jon Davis were 2nd and 3rd) it felt 
like a good job
done to me.
[PS:  Lindy, guess which orange shorts that you hate just got LUCKIER?]
Rog, if you get this before your trip, good luck in Kiev, hope you enjoy 
the kielbasa and pivo!
LEE
