2001 World Champs News
======================
Firstly George Batiuk reports a very productive meeting with Joyce Hager,
the AMA Executive Director who reviewed plans and progress so far.
All appears to be on track.
There has been some discussion on these pages about a plan book etc..
The reason why this is not going to happen is a simple question of
economics and avvailability of the right people. Previous World
Champs in the US had Plan books done by the NFFS. In both cases
these were started a year in advance of the Champs. In addition the
plan book produced for the 93 event required an up front payment of
about $20,000 to produce the quality publication. Many people were
disappointed by the quality and veracity of some of the plans.
For the 2001 event neither the people nor the money are available.
However with SCAT there has been some discussion as to iwhere the SEN and
our print publication SCATTER falls. We decided that SCATTER would
be an annual publication covering some FAI FF events of note. One
was produced covering the US TEam selection, that included some
technical analysis. It appears that SCAT may produce a SCATTER
to cover the 2001 World Champs - no attempt is being made to call
this a plan book, but it is not excluded that if some plans are contributed
they will be included. For budgetary reasons would not include
all contestants airplanes. Details of this will be available later.
Look for the elliptical tips..

In Reply to "Who still builds" David There are still a few of us who
build our own models and do well with them. Look for the elliptical tips..

10K oven

Chris,
$10,000 for an oven !!!! ??? ....any chance of lending me the fare to the WC
this year? Even two weeks at Ronnie Scott's with Charlie Watts and a
session, doing Sax overdubs for Mick Jagger, didn't pay enough to make the
trip !! ;-))))))))))))))))))))))

King / Kaynes Simulation update.
================================
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
Several people have asked me for a list of the equations and methods used in
the Glide sim part of the program. I have finally got around to extracting
the maths from all the relevant cells, Quite a long job!!! I can email
the info to anyone that wants it. The nomentcalture needs considerable
revision but this version should give a clearer idea to myself, as well as
others, as to what I do in the sim.
While doing it I discovered some mistakes in the cells. Although correcting
them did not effect things much, I have a new version with both the
corrections and a new feature added. I have added a rough simulation of
how the model stalls when the Alpha (wing) becomes too high. To run it in
this configuration you run a macro that changes the program. The problem
with that is it gets rid of the effects of Re No that I took so long to
program !! This feature is just a rough interim development, that is only
of limited value. One day I hope to develop the sim to incorporate stall in
a much more refined way that still takes account of Re No.

Roger,
Am not going to try to top Team Gewain in the oven department, but would
like to point out how stability is increased in critical transducer
applications.
After a thorough cure with clamps etc, the parts are "post cured" at a
higher temp w/o clamps. For really critical apps, cycling between freezer
and oven is good. Recommendation was for 50F above max service temp.
This is probably real overkill, especially when compared with wooden
airplanes, but the thermal cycling did make a noticeable difference.
Probably acted as stress relief.
Geared Nelsons
=============
Author : simpkinsdw
Evgueny Verbitsky has designed a way to mount a 4 to 1 reductor gear on
existing Nelson 15 side and rear exhaust engines. He knows that many flyers
use Nelsons and is working to make the change-over cost as low as possible
for those who are interested in trying a geared unit. He will pay postage
both ways but you must use USPS (United States Postal Service) Global
Express. To use FedEx, UPS, or other sevices are too expensive.
New parts would include geared unit, prop and spinner, brake, fuel system,
engine mount and cowl. He must know the ID and OD of your clamp ring so the
engine mount will be the correct size. Price is currently being worked up
and will be posted soon along with Evgueny's e-mail address.
To view a photo of the geared Nelson, see the attachment
Please do not contact the sender of this information. It is only being done
as a favor. You must deal with him direct.

By now many of you are aware that FAI MODEL SUPPLY has very good June
rubber in stock in all sizes. ( per three independent test people that
tested 3 lots of 1/8", other sizes are from the same lots ) For those
of you that have outstanding orders on us, please be patient, we are
filling orders as fast as we can. Thanks, John

Old plan books are indeed a joy to read, to browse through all those
then-innovative ideas, and to see what has remained and what has not. Tho
problem is - as you said - that at some moment the books become rare, hard
to attain and so on. What about making the next plans book into the net,
and updating it continuously, whenever some new plan becomes available?

Digital Servos Update
=====================

Hey Guys!
For all of you who have ordered Graupner Digital servos for me, i would
like to give you an update on the status of our action.
We finally ordered a batch from graupner directly in germany. Graupner
delivered to my address in germany and my father already sent a package
containing the servos to the US. So finally, after all these weeks, the
servos are on their way to us. As soon they arrive, i will let everybody
know and i will distribute all orders. In addition, Allard already
received his batch of servos and everybody who ordered from him (mainly
the frensh guys) will receive their servos within the next few days as
well.
For all of you who have not ordered servos yet, we still have a couple
left to sell for this special price.

Hotboxes/bodies
===============
Sender : This email address is being protected from spambots. You need JavaScript enabled to view it.
Roger. glad to see fellow Kiwi Jason Magill has found the perfect way to cure e
poxy,
getting married. Here in New Zealand it is winter, so pop the electric blanket
on,
put the moulding between Jason and Bride and it should cure in no time.
My hot box is very simple, a galvanised iron covered workshop. Pick a sunny Tau
ranga
day, shut the door and windows and solar power does the rest.
After curing has been known to be done here by leaving mouldings on a windowsill,
solar heating does the rest.
Dave Ackery has commented on who builds anymore. On our national team, of which
Dave
is a member, there is a mixture. He has been getting model drawings together fo
r
our national bulletin, FFoNZ NeWZ, which I edit, and there is everything from o
riginals,
mainly using hardware components from overseas, to RTF models.
I am reserve for the F1B team. My own models range from modified RTF to bitsas
using
a mixture of something borrowed, something blue.

Endless Summer T shirts?
========================
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
Dear Roger,
First question, in the last issue or so (588, 589) of the SCAT news
one subject by somebody was the availability of Endless Summer T shirts for
the up and coming World Champs, well before I could get his address and
express an interests in the shirts the SEN letter got deleted, so could you
repeat that article about the T shirts or just send me his E-mail address.
Next question, I would like a point of contact (CD, Asst CD, etc.) if
possible for the contest on the weekend before the World champs as I'd like
to fly in the mini events and would like a flyer for that contest. Thanks
allot Bill Gannon

[All old issues of SEN are kept on-line at the
SCAT Website - www.aeromodel.com/scat - under the section News and events.
You can get to back numbers there.
Also there is a contest calandar section that has about the contest you
are talking about. One of the CDs is Juan Livotto - This email address is being protected from spambots. You need JavaScript enabled to view it..]

Prompted by recent SEN reference to things on the web site I checked out
what was there and request one change. There is a link to the 1999 World
Cup results. Could you change that to link to the index of all the FF Wor=
ld
Cup results:
www.fai.org/aeromodelling/competitions/free_flight/wcupmast.htm
Thanks
Ian
[We have corrected the reference on the SCAT web site as Ian suggests.
Readers should note that this site is the definitive source for International
Free Flight Contest results - Includes World Champs, Euro Champs as well as
World Cup events. A sterling job by Ian Kaynes!]
