Some people did not get the announcemnt that we sent at the beginning of
We regret to inform you that
World Champion, American, Best Rubber Flyer ever, craftsman, determined
competitor, gentleman and friend ...
Died today of a heart attack.
There will be not funeral, nor any service regarding Bob's passing at
We are asking people not to call Jean White because she simply
cannot field phone calls. Her hearing is very, very, bad, and her health is
fragile. Right now she has family members with her to help her.
But please feel free to write to her at:
1030 Norumbega Drive
Monrovia, California 91016-1833
You can e-mail messages to Al and Judy Hotard at.
and they will see to it that a copy of the email is delivered to Jean.
Note that we got Al's e-mail wrong in the first announcement and
this one is right.
Truly condolence for Bob.....He was a great man.....
Damian Zulic from Slovenia
It shocked us very much to hear Bob White's death. He was the greatest
flyer and the best friend in the world. His name will be rememberd forever.
We send our united and sincere condolence.

The Illinois Model Aero Club sends it's most heartfelt condolances. We shall
all miss him. Ed Mate President.
My next Max is for him..
May god bless him. We are a lonelier world and free flight community
without him and heaven is a richer place for him being there.
So sadly missed and I never had the chance to share the air with him. My
next max is for him.

Southwest FAI Challenge
Those that rolled the dice and came over to El Dorado Dry Lake were rewarded
with fabulous weather and a darn good contest. Friday mid-day was a bit
breezy, up to 10 MPH, but by late afternoon and up until dusk we had perfect
test weather. When we arrived at the field Saturday, the thermometer read 30
degrees. By 11:00 most of us were in T-Shirts or light sweatshirts. There was
a slight breeze to the north, but nothing to prevent the extended max times for
round 1. By the third round, the thermisters were not moving and the streamers
were hanging on the ground. We were greeted by a sudden wind burst at the
opening of round 6. Once the wind picks up on the lakebed, it usually stays
up, but not today. Those of us that flew in the 9 MPH "lull" arrived back at
the pole after our chase to find the wind had dropped to about 4 MPH. Round 7
was a repeat of round 6. By the time we got to the flyoffs at 3:55 (that's
another story) conditions were perfect. Rich Rohrke nailed his glide trim in
F1B and posted an excellent 379 to beat my 357 in "cool" conditions. True to
form at this contest, the F1A flyers provided a bizarre twist in their flyoff.
It looked like Mike McKeever & Brian Van Nest would have the issue resolved in
the first flyoff round as both glided to the ground well below the 5 minute
max. Unfortunately, they both glided to the ground in exactly 238 seconds.
The second flyoff round was won by Mike at 348 to Brian's 260. It was a
welcome site to see a little power activity as both Randy Archer and Ed Carroll
flew F1C in pursuit of AmCup points. Tony Robertson won Saturday P-30, edging
Las Vegas local Gerald Antonucci & Bob Beecroft.
Sunday's Champagne Flyoff for the mini events seemed to be well received with
John Clapp winning F1G at 234, Mike McKeever winning F1H with an outstanding
259 and Tony Robertson winning F1J at 299. The remaining 5-Round contest was
a little anti-climactic because the conditions were almost too good and it was
pretty obvious that the Champagne scores would determine the contest results.
However, other than John Clapp who was sweating out a win for AmCup points and
Ed Carroll who just plain had a bad day, it was a very relaxed gathering.
There were a total of 15 contestants in the mini events combined. Of the 75
official flights posted, 65 were maxes. It was also nice to see former US Team
Member and competitive heavy weight Willard Smitz, who now assists Dick Wood,
throw up a few officials in F1G. John Oldenkamp bested Bob Beecroft to take
the blue glassware for Sunday P-30.
Thanks to Bob Beecroft, Jon Zeisloft & Harry Steinmetz for their help in
contest re-organization and strategy, to Harry for again serving as CD and to
John Oldenkamp for manning the official's table. I again want to thank those
of you who wrote and encouraged us to re-schedule the meet and made the drive
(twice for the Smith's) somewhat on a leap of faith.
If you have an opinion for next year's calendar date, please send me an e-mail
or grab me on the field and tell me what you think. We have to commit to a
date by early January or before. At this time, the consensus is to schedule
this meet the weekend following the Sierra Cup to accommodate our European
friends who will be here for the Livotto and the Sierra Cup and maybe get a few
east-coasters to stick around for another week. There is a lot to keep you
occupied in Las Vegas in the week between meets.

Results of the 21st Annual Autumn Cup, Seguin TX, USAF Aux Field
For 26 years the Texas Free Flight community has been blessed with the
use of the USAF Aux field just outside of Seguin Texas. During that time
period there has been an on-going interaction between the model
community and the Randolph Air Force Base who utilizes the field for
Pilot Training, (In use since the early 1930s) Our Special thanks goes
to Russ (Bear) Snyder, Lt. Col USAF Retired. Russ hailed from Laredo
Texas, his carreer was as a Fighter Pilot and included 184 Missions in
Viet Nam in the F-105.
When Russ retired to the San Antonio area he was instrumental in getting
the Seguin Field opened to Free Flighters in 1979. The club that has an
agreement with the Air Force is the Tri-City Modelers. A club that
originated on Randolph AFB many years ago and has had many noted
modelers as members including Nationally known U-Control Stunt flyer
George Aldrich, National Jet Speed record holder Jimmy Summersett, (who
was always a Free Flighter when not in the circle), and many others.
Russ Snyder was the modeling community point person to the Air Force for
the 1981 US National Free Flights Championships, and the US Free Flights
Team selection Finals in 1984 and 1988. It was Russ who smoothed things
over with the Air Force when flyers competing at the team finals in 1988
cut thru the fencing around the field to retrieve models.
Thru all these years Russ has been the Seguin Field Coordinator. And
while other military fields have been used and then lost to Free Flight
activity, we have continued to have access on weekends and Federals
holidays and with a controlled agreement on pre-planning and scheduling
a year ahead of time we have been able to hold all contest as advertised
with the exception of one time when the use of the field was denied for
Army training exercises.
Russ has also just handed over the reins as the District Free Flight
Rules Committee member to Mike Fedor after 14 years in that role.
I would believe that all of our Free Flight Community, nation wide, owes
Russ a standing ovation for his role in securing and maintaining the use
of the Seguin Field. Russ is our John Wayne, our example of what it
takes to not only ge the job done, but to do it right. Doing it with
honor and integrity, settling for nothing less from all of us who thru
the years have richly enjoyed the use of the field, Not just for the Big
contests, but the fun of flying each weekend, the trimming sessions and
the $5.00 pots for the little club contests. Russ could not make the
Autumn Cup contest this past weekend because of health issues but he was
in constant touch with us via the Cel phone insuring that all was going
smooth. So from all of us, THANKS RUSS!
The Seguin field is now considered a secure site and it's use is tightly
controlled. Use of the field now requires the single entrance to the
field to be locked at all times (yes, even during the contest) and it's
access during the contest is monitored by members of the Tri-City MAC.
This means that flights that go off the field require a club member to
come open the gate for re-entry.
It also means that Faust Parker and Reid simpson who CD the three
contest held at the field annually constantly monitor the wind direction
and speed to provide maximum field use for all testing and contest
flights. The goal being to keep the models on the field and keep
exiting/re-entry to a minimum. Since both Faust, Reid and other club
members compete in the contests it also helps the interruptions to their
The Autumn Cup contest November 12-13th, enjoyed good weather. Not that
the wind was always low, but it was always going in a direction that
allowed the maximum length of the field. On Saturday morning it was up
to 10 - 15 MPH at times, but it did not maintain a steady wind speed nor
hit us with heavy gusts. It varied with the thermal activity and by
shortly after lunch it was down to around 7 - 8 MPH and was very low by
the time the last round was over. On Sunday it was calm until 9:00 when
it went to 8 - 10 MPH and then by 1:30 it had gone calm. The maxes both
days were set at 2:00 minutes to allow for DT-ing the models on the
field. As it was, only 4 flights went off the field in two days of
The best of the contest occurred at 2:00 PM on Sunday when The F1J and
F1P events set the max flight times at 5:00 minutes for the flyoffs
because of the dead clam conditions. Watching the F1J models of Faust
Parker and Jackie Sheffer float overhead and drift no more that a few
hundred yards was great. And the F1P models of Reid Simpson and Jackie
Sheffer just hung overhead with Reid's model setting to the ground at
6:16 no more that 25 yard from the launch point was the perfect ending
to a good fun filled contest.

F1A historical query
I've realised that there were three significant technical developments
in F1A history that I can't put dates on:
- the introduction of the clockwork timer
- the introduction of the start pin for clockwork timers
- first use of wing wigglers got circle tow
If you know who was the first to use any of these innovations, where
they were first used in a significant contest and when this happened,
please e-mail me and pass on what you know about it. I can be reached
I use a miniature glass bead thermistor from RS-Components Australia
(they may also supply them in branches in other countries). The RS part
number for the 47k version is 151-158 (they have values from 1k to
470k). These are fast response types suitable for thermal measurement
in our field.
Go to their site and search on the part number to see the range:

I understand the reasoning behind this method, but I'll stick to
my carbon capped 6mm medium balsa ribs for one simple reason. I find
that, unlike thinner ribs, if you knock the tip off with thick ribs the
break often runs across the full chord through the middle of the ribs
rather than splitting them out of one of the panels. That makes for an
My solution for avoiding bowing is to use a 12" Permagrit sanding block
to sand in the dihedral angle. The permagrit surface is coarse and cuts
fast through both balsa and carbon D-box shells with minimal sanding
pressure. It doesn't clog, either.
A new software to design F1A glider
We are delighted, my brother and me, to send you a software which allow
you to design your own glider in a very short time.
Thanks to F1A Tracer, you can design your own airfoil
and then you can save the coordinates in *.dat size file.
Then, with the coordinate file (*.dat), you can test your aifoil
in the numerical blower Xfoil (that you can download on this
website : http://raphael.mit.edu/xfoil/ ). So you can change the
drawing of your airfoil to reach the better performances you ca
hope. (Cd, Cl, lower rate of fall .)
When you airfoil is planned, you can design the plan of your next glider.
The soft calculate the total area that is very convenient.
In conclusion, when the total designing of the glider is done, you can have
a general idea of your glider clicking on 3D viewer.
We use this software, which we designed during approximately 4 months,
to design all of our own gliders and we think that it can help
everyone you like designing his own glider like us. What we like in
free flight, it's designing gliders (airfoil.) and
then testing our creation in the fields.
Thanks to this soft, it is very easy to share plans : you have just to
send by mail the *.pla file which is the plan file. But of course, if
you prefer to send the *.jpg plan file, you can do it clicking on s
“save plane jpg.
There is just one problem. To use this soft, you need to have a quite recent
graphic board in your computer with 128 Mo of memory at least we think.
So of course you can test the soft to see if it works well but if you
haven't a recent computer you can have some problems. If you have
some question, please send us it : we will be very happy to answer you.
Please send your email to this both adress at the same time :
But we will be very happy if you send us your suggestions about the soft
and if you tell us what you think about it. We envisage to make a
other version so we need to know what you think about the soft.
To download this soft : please click on this i
link : http://termirc.free.fr/f1a_tracer_v1beta.rar
We hope this soft will be a good means for you to design new gliders.
