Roger,
Please post in your next SCAT transmittal. It's a bit wordy, but I think
pertinent. Thanks, Dave Johannes
It is with great sadness that I report the competitive FF community has lost
another of its dedicated members. The man many of the SCAT EN readers know as
Robert/Bob Johannes, and I know simply as Dad, and my kids know as Grandpa
Fix-it, succumbed to cancer while sleeping the night of 6/29/04. He had been
battling a recurrence of cancer for several months. This time around,
treatments were not successful in eradicating the cancerous tissues.
He died at home, had not had to deal with very much pain (with a significant
assist from some powerful medications provided by the Hospice folks), and was
generally lucid right up to the end. I was able to visit with him again 2
weeks ago. Among our last conversations, he explained to me what an eyedropper
fuel system/timer was and how it worked. I'd read about this setup in
reference to the upcoming "Dakota" competition to be held at the NATS in August,
but had not seen or heard of this method for timing an engine run before.
As those of you who know me are aware, I've only been involved in competitive
FF for a few years. My first ever practice launches and official flights
occurred the weekend of the 2000 Sierra Cup, at Waegel Field, in the Sacramento,
CA area. Those first experiences were with Dad's hand-me-down, strap-down,
1/2A model (which he called the "Rotator," due to its nice axial roll pattern
while under power), which I flew in F1J. While the Rotator was a fine 1/2A
model, it could not handle the full 7-second engine run allowed in F1J. Under
the acceleration being produced by the reworked CS 0.049 that came with the
model, which was turning a standard APC prop. at nearly 30,000 RPM, the
wing would "give up" after about 5 seconds and the model would "go over the
top"). So we
had to settle for 5-second engine runs and the model therefore was not a very
competitive F1J; but it got me my first maxes and I was immediately and
forever hooked on the collective set of challenges and rewards that contribute
to the joy of competitive Free Flight.
Based on "our" experience, we both came to ponder the merit/rationale for the
Builder of Model rule. While I'm not attempting to advocate either side of
this debate here (and realize the BOM issue is like a civil war situation, with
very polarized positions, that won't be settled without some blood letting),
I feet it deserves comment that I'll be attempting to carry on my Dad's FF
legacy for the rest of my life; and I never would have had the opportunity to
experience the joy of FF competition, had it not been for the "relaxed" rules of
FAI-level competition. However, I would welcome the opportunity to discuss
with SCAT readers the pros and cons of the BOM rule, or the merits of the
underhand launch (of which Dad also was an advocate, and you will always see me
employing, at least with "bunters"), at some other time.
Back to the point; I've only been around competitive FF for 3 1/2 years. So,
there's a lot about Dad's accomplishments (and the science of FF in general)
that I don't know. I would, however, like to acknowledge his achievements and
gestures of which I am aware. Any other remembrances his friends/peers would
like to share would be appreciated.
Dad was a good FF modeler as a young man, as evidenced by his early FF
records and membership on the Chanute Air Force Base's FF Team during the 1950s.
But it wasn't until he retired in the early 1990s (following a distinguished
career in aeronautical engineering that included his rising up through the ranks
to a managerial position with the Flight Control Systems Division of the Air
Force's Flight Dynamics Laboratory at Wright-Patterson AFB {helping develop the
methods and technologies that allowed man to achieve and survive supersonic
flight}; followed by several years as Deputy Director of NASA's Dryden Center
at Edwards AFB {family and friends were able to be VIP witnesses for the first
Space Shuttle landings, very neat experiences}; and finally several more years
with McDonnell-Douglas {which Bob Mattes will tell you is the only part of
Boeing that is still profitable}), after a long hiatus away from the sport,
that he really hit his stride.
By the late 1990s, he at one time held three AMA records, for 1/2A, B and D
Gas. As far as I know, he still holds the B Gas record. By that time he'd
also transitioned into FAI-level competition. Among others, he won F1J at the
1998 NATS, and won the F1C competitions 2 years in a row at the 2001 and 2002
NATS contests. However, I think his proudest moment was placing 3rd at the
Sierra Petite last fall at Waegel Field, behind Dave Shirley in 2nd and me with
my first 1st place finish). The picture Bridgett Brocks took of the two of us
as the sun was setting that evening, with our grins from ear-to-ear, will
always hang in my office.
In addition to being very knowledgeable about aerodynamic principles and the
various tactical aspects of FF competition, Dad was an extremely talented and
innovative builder, and an "engines expert." He rebuilt engines for the
challenge and just plain fun of it. On several occasions, I observed him
hand-lapping pistons from engines of his competitors, at the flying field,
between rounds, always yielding significant performance improvement
(and gratitude). Dad
was happy to share his practical knowledge, real-life experience, and even
equipment/supplies from his flight kit. I challenge myself and the rest of the
SCAT readers to live up to the intense, yet friendly, level of FF statesmanship
exemplified by Bob Johannes.
For those that would like to participate and will be in attendance, two
informal "spreading of the ashes" ceremonies have been planned. The first will
be Wednesday (August 4th) morning, at the upcoming NATS in Muncie, IN. The
second will be held at Lost Hills, CA, during the Team Selection Trials this
October. I will make sure those in attendance at these events are aware of the
specific times and locations.
Should anyone feel compelled, the family suggests contributions to the USA,
Jr. Free Flight Team, in support of their pending trip to France for the World
Championships, in lieu of flowers. Please send any contributions in his name
to Brian Van Nest, Junior Team Manager, 12346 Cheyenne Drive, Bishop, CA
93514.
I will be dedicating all future maxes to the memory of my Dad, and ask that
each of you dedicate at least your next max to him, and that unobtainable yet
never ending pursuit of perfection that is FF competition.
I look forward to seeing each of you again, or meeting you for the first
time, on the flight line.
David Johannes

Since my legs do not not permit me any longer to fly F1A, I want to sell all
of my F1A equipment and go on with F1B (I now really qualify to fly F1B I
think, since I hope be 60 next october!).
The items for sale are:
1) (Russian) model box with 4 F1A's. 3 of them are of the HIHI design (by
Cenny Breeman and myself). The wings were made by Victor Pisanny, the

many times and have repairs, but are doing very well; the last time I used
them was in Lost Hills last February.
The fourth model is a brand new 5th generation long model designed and made
by M&K and also has 2 stabilizers; it was flown only for 10 flights or so,
and also last used in Lost Hills last February.
All 4 models have the Danish type (Torleif Jensen/Nyhegn design) electronic
timer incorporated. This timer is programmable with a Palm IF (not included,
but obtainable at very short notive from Torleif Jensen, Denmark). Model box
can accomodate 5 F1A's.
2) 1 special design F1A for rough weather. Wingspan 1,830 mm, very thin
(3.2%) rather flat (5,0%) airfoil. Wings made by Pisanny, fuselage and (2)
stabs M&K. Danish electronic timer. Model was trimmed and competition flown
only 10 times or so.
3) 1 set of unused HIHI F1A wings made by Victor Pisanny
4) 1 set of unused F1A wings as in item nr. 2
5) 3 uncovered stabs with carbon d-box, weight 6 gramms , size 497 * 85 mm
6) 3 M&K made finished stabs total weight 6 gramms, size 469 * 80 mm
7) 1 M&K made finished stab total weight 6 gramms, size 478 * 82 mm
8) 1 new HIHI fuselage without hardware made by M&K
9) 2 reels with 1000ft waxed kevlar towline (Bradley)
10) 2 Russian made alloy towline winches with gear and 50m kevlar towline
11) 1 Maxaid winch with extended drum with 50m dacron towline, plus 3 spare
drums with nylon towline

Argentinian Nationals
=====================
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
Dear Roger ,please include in a future S.E.N. the following report of the
Argentinian 58 National Championships. The NATIONALS include free flight,
radio control and control line competition.
This was a good test of
the acomodations (rooms and food)With about 450 participants,and counting
helpers and family, rooms and meals for about 500 persons were provided.
The hotels
had been upgraded and the food service was good and in time.A big improvement
over what we had in 1989. The hotels are used on a rotating bases by the
retired members of labor unions.There are no fancy menus,but the food is
simple, clean and heathy.
They also have improved the acces road to the flying area.The Air
force base is no longer in service.With this new acces we will be saving about
five kilometers,but ,better than that,we are not going to drive through the
base main entrance. The field has been cleaned up of
bushes and dead trees and is farmed with rotating crops.By late may it is all
cleared up .They plan to have 3 designated launch areas that will cover all
posible wind directions.
Unfortunatelly ,for this year contest we had some rain and wind.Very
unusual to have rain in this part of the country at this time of the year. The
last ten years weather report still favor late may for our interest.
They flew F1b and F1c team selection finals on friday in good weather
conditions,we flew F1a nationals saturday, the last five rounds with
some rain. Sunday they flew F1b
and F1c nationals to complete their team selection. Only four rounds were
completed ,but that was suficient to select the teams. The monday F1a
team final was cancelled because of wind and rain and will be completed
at a later date.
I have seen great progress in F1a ,with a lot of M & K late electronics,so they
will be very competitive in this class.Same thing for F1b with a strong team
with modern equipment.In F1c Zito and son are in with later
technology(reductors)and a third team member with a lot of local experience.
After all the delays and cancelations,the only happy group was the
indoor flyiers. I didn't have a chance to visit
the R.C. sites or the control line circles, wind and rain are not my favourite
enviroment.
I had some great expectations,the last time I flew the
nationals was 1965.Same central location ,the weather was perfect.
We will be back next year for the World Champs and the wether will be good.
F1H Circle Tow Hooks
====================
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
Roger,
I wonder if someone in the SEN community could supply me with a drawing of a
circle tow hook suitable for the slim space in an F1H glider? I am in the
midst of a "comeback" after a 40-year layoff and the "catch-up curve" is
steep. Lee Hines has been enormously helpful in tracking down F1A material
and giving some tips on catapult glider! Currently, I'm trying to do some A1
and F1H work to get warmed up. If George Bush Senior can jump out of planes
at 80, why can't a guy in his 60's tow gliders???
Thanks for your efforts and contributions.
