Scat readers:
The 2003 Muncie Nats has come and gone, blessed with fliers from near and
far, impressive juniors and seniors, excellent weather by mid-West
standards, soft green grass, tall corn and beans, at least two records set,
no known serious injuries (one motorcycle tumble and shoulder sprain), fine
FAI and special event directors, decisive FAI flyoffs, valued input by
competitors, on-time Awards ceremonies, attractive Award plaques, no
controversies or protests, much fun, and tremendous support by 46 super
volunteer ladies and gentlemen, including a great Assistant CD, John
Lorbiecki.
Thanks for being there at the 77th Nats.
Your comments and suggestions by return e-mail would be welcome.

fyi.
the eight gas events i refered about was the a m a gas

1/2a classic.
a/b classic.
c/d classic.
and i did not mention anything about the puppy event
what so ever.
i hope this clears up your confusion about this and
you and i are on the same sheet of music.
thx don.

I understood what events were flown. That is why I changed the

3rd&4th place F1B scores at NATS
================================
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
Hi Roger-In talking with brother Jim, I recall him stating that there was a
tie for third so they had a 5 min flyoff-they both maxed therefore
requireing another flyoff-do not know why 1st and 2nd place scores are as
presented.

NATS F1B times

Hi Roger,
Andrew Barron and Ed Wiley tied for third in the 4 man flyoff. (We had =
two timers on each flyer, and all 4 had the exact same time). They then =
flew an additional 5 minute flight, which both made. They went for 7 =
minutes and Andrew had the highest time. This gave Andrew third, and an =
unusual total time from a casual observers view.

Andy Barron's score......
=========================
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
In regard to and Barron and Ed Willey's score. This strange number is due to a
tie, in which both competitors chose to fly off. Of course, they both made the
first flyoff and had to go to a second flight.
Thus, the scores higher than the winning time........
Oh yeah, Thanks to Walt Rozelle for running the event!

Updated World Champs Results
============================

I have updated the results of the World Champs on the FAI web site to tidy
up 2 software glitches (no change to the real results, just presentation):
1) This was the first Champs with more than one extended max round. For the
people who did 7 x180 but did not make the flyoff I had shown the result in
the form 1260 + 113e which hides the detail when 2 flights are involved. The
update gives full flight-by-flight scores
2) My code translated the abbreviation YUG into Yugoslavia, but the country
is now called Serbia and Montenegro. Maybe when they get around to a new
abbrievation for this it will be SAM, to confuse with the antique
modellers.

F1D Invitation
===============
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
I first witnessed Real Thermal Pickin', Fuse-Lightin' Free Flight and its
great community when the Nats came to my home state--1987
Lincoln, Nebraska. Up
to then, I had dabbled with HLG since about Jr. High. What I saw and felt at
Lincoln inspired me to get serious with outdoor FF a few years later, and I
progressed to competitive F1B by 1997. Although that was short-lived, I
enjoyed a few moments of success, such as making the F1B
flyoff at NorCal that year,
and a first day string of maxes at '98 Team Selection, Palm Bay.
One distinct pleasure accompanying AMA events is to be able to walk the
flight line, scratch, sniff, and oogle over other modelers' craftsmanship,
innovations, or design ideas. I missed that while flying FAI. What
should I do
instead--send fan mail to Russia? Ask flyers which factory they support?
Compliment wing stripes? At any rate, I didn't really feel
like a *modeler* while
trying outdoor FAI, and yes, I understand the much work involved even in
assembling Buy Tech parts--I did that, too. (I really admire those
who construct
most all their model--Ghio, Norval, a few others.) But to settle in being a
"Sportsman?" Nyet!
Thankfully, in indoor FAI (F1D) everyone still builds what they fly--a
machine shop is not needed, even to make your own first-rate VP.
Contests are
seldom won by finding lucky air. You usually get what you
deserve...or less.
There's no sour feeling in getting beat by a modeler flying what he/she
constructed. My foray into F1D has proven very satisfying, even
though the learning
curve is brutal, and no Cat IV sites are available on West Coast.
After a two
year struggle, I was somehow able to do four 31+ flights at
Kibbie Dome ''03,
including site record for 55cm F1D.
This is not intended to lure away anyone presently satisfied with outdoor
FAI, but *is* an invitation for any modelers who may share my ethic/dismay
regarding Buy-Tech competition. The good news for beginners--recent
rule changes
have made F1Ds slightly heavier and smaller--no microfilm needed.
The majority of the experts (especially Steve Brown, 4X WC) are glad to
help any struggling
newcomers. Indoor isn't for everyone. But through the struggle appears the
satisfaction. Anyone wishing to get started, get plugged into resources, or
just discuss F1D may email me.

TTails
======
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
Anent Wilkinson's piece on the Real Gas event, I would say that there is no
event using gas these days, except for old timers.
Powered perhaps, but so is
F1B. We need a new term for present day engine-powered events in Free Flight.
As for Andresen's piece on pylons, the taller the better? I say no. The
true center of gravity of gas models is well above the wing root chord. The
higher the pylon the more engine downthrust is required.
There are full scale
airplanes that have T-tails. In every case, the wing stalls before the tail.
Otherwise, back to the drawing boards. (Now, there is an ancient term). I
spent a delightful two weeks at the wind tunnel in south Pasadena,
California in
January 1951 having come from Baltimore, Maryland on the east coast. The model
represented the P-6M, a water-based design for the US Navy. It had a T-tail
to keep the hull spray off it during takeoff and landing. The horizontal tail
showed no tendency to waiver from a linear lift curve until well after the
wing was fully stalled. Otherwise, the test would be over.
I worked on another T-tail airplane in Columbus, Ohio at the North American
Aviation facility. This aircraft was small, to fit the concerns of the U S
Marines for operating off car paths in dirt. At the time of
design it was called
a COIN aircraft, but really was used for forward aircraft observer work in
Viet Nam. I will bring a model of it to the next SCAT meeting

"T" tails
==========

In response to (Down with T-tails). I thought the idea behind the "T"
tail was to place the stabilizer high enough to fly in clean air. Are
you suggesting that the air flow from the trailing edge of the wing
flows upwards?? The stall problem with the 30:1 nordic sounds more like
a stability problem in the design of the airplane, not the position of
the stab.

Winding hooks
==============
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
Roger,
One of the problems rubber model flyers have is keeping a fully wound motor
centered on the winding hook. That certainly has been more of a problem for
me since I went to narrower motor tubes for F1G. In Eloy last Janurary for the
first round, the problem caused the hook and motor to hang up on the fuselage
side and the Montreal stop kicked in after a 10-second motor run (the flight
was 80 seconds total). I had thought that making a 12-inch motor tube for a
9.5-inch motor (12 strands of 1/8 Tan II) would keep enought tension on the
system to straighten out the hook...not so.
I make my own winding hooks from aluminum alloy. Maybe that's part of the
problem, but I've had problems with commerically sold hooks too. However, I
may have some new insight into the solution of the problem.
It didn't come in a
flash, but over a series of weeks after noticing that the motor on my P-30
aluminum hook kept creeping towards the open end. Upon inspection, I noticed
that I had engineered the hook (a number of years past) to taper the amount of
metal from the closed side (more metal) to the open side (less metal) in line
with the torsional stress on the hook....bad idea! If you have a round
tapered metal form, a tightly wound rubber motor will
naturally seek the smallest
diameter. That's the insight! I changed said hook to reduce its diameter at
the closed end to be more like the
open end. No more motor creep.
One of the classic "solutions" to the rubber creep problem was to form the
part of the hook where the motor sits into a "Z-bend." My suspicion is that
this technique originated with music wire hooks for Indoor flying (which I have
done for several years when it's cold and blowing in Chicago). Converting
this geometry (the Z-bend) to aluminum might help,
but it makes more sense to me
to use the added dimension of aluminum sculpture (as opposed to uniform wire
sizes) to form the hook so that its diameter at the place where the motor is
attached tapers from the middle of the hook (smaller)
to the ends (larger); thus forcing the motor to creep into the
desired location on the hook. By the
way, Jim Richmond once told me that he uses a
simple square-bend hook to keep the
motor centered on his Indoor models.
Luckily, I lost a few winding hooks last week at the Nats and was motivated
to make some new ones. I'll let you know they work out.

FYI, Wake scores @ the NATS & higher orders
===========================================

Hi Roger,
I am almost positive there was a FO for 3rd and 4th places between
Andrew B and Ed W, which accounts for them having higher scores
than the winner, Charlie J.
To interject[at the risk of tweaking the SEN-Master], in my hmbl opine,
Catapult Glider is one of the higher forms of of the FF Universe, as is
Hand Launched Glider.
In fact,on my upcoming 2004 trip Down Under to OZ and NZ, I am ordered
to bring some CLGs and OHLGs, or don't bother showing up! :>)
Last, but not least, Kudos to our FAI Team members and their helpers
for their efforts in Hungary.
See you downwind after you rest up!
Ciao,
Leeper
