RE: East Coast Friend, Bill Smead
=================================
Hi Joe,
Thank you, Walt Rozelle and Ron Sharpton[I got your telcom] for bearing the sad news my way.
He was a fine gentle man, a tough competitor, but especially a good and trusty friend.
I was fortunate and grateful to him for being my chase bike guy at the 2000 FAI Palm Bay finals.
Since he knew that field like the back of his hand, I did not worry or need a GPS...he just went out
and brought them back. No sweat for Gliderguy Bill!
I will miss him.
Ciao,
Lee

Lee Just a little note to let you know that one of your HLG and catapult friends died last night.
Bill Smead. He wasn't feeling well a couple of weeks ago and went to the hospital Found cancer
about the size of a golf ball in the brain behind the left ear Was inoperatable and was traveling f
ast. Don't have any details yet. Nancy Smead 22 Holly st Deland, Fl 32724

Low Tech Trimming and Greeks on a plate
=======================================
Red Faced Replies to Dick Ivers and Chris Murphy.
Dick
Sorry for the mess-up on the freewheeling prop business. I did the work
several years ago and it was published in the January 2000 issue of our 'SAM
35 Speaks', as a contribution to a discussion going on at the time.
Unfortunately the passing years led to a 'senior moment' in the memory
department. When I took the trouble to check back I had drawn two vector
diagrams; the first with the propeller pointing straight ahead to shew, as
you so rightly said, that there is no lateral force in that conditions; the
second diagram has several degrees of right sidethrust added which gives a
net right turning force from the blades.
When drawing this vector diagram it is convenient to use an amount of
sidethrust that brings the bottom blade to its zero lift angle to the
vectored flow. There is then only a small drag force to consider on the
bottom blade and it is to the right anyway. The aerodynamic forces on the
upper blade are similar to what they were in the straight ahead position (to
the right) but are larger because of the increased (negative) angle of
attack.
As well as the sketches of vectors I also made some small indoor gliders
where a propeller could be pinned onto the front at large angles of offset.
The forces on these gliders did not appear to be large but it was
interesting that as well as the right turn with sidethrust it was also
possible to see nose down and nose up tendencies with down- and upthrust.
Chris
Sorry about not crediting the New Zealand navy with the 'Achilles', I just
did not know that that was where she came from. I did not mention the
'Exeter' because the 'Ajax' and the 'Achilles' were the two names used by
Keil Kraft for their kits at that time. They were usually talked of as 24"
and 30" versions of the same design but to my mind the 30" 'Ajax' was a much
superior aeroplane. But what do I know. Nowadays the 'Ajax' is an
endangered species whereas flocks of the horrible 'Achilles' regularly
darken our skies.

EFFC Ingleside
==============
Wagner This email address is being protected from spambots. You need JavaScript enabled to view it.
Roger, Could you please post that for our meet on May 1st & 2nd, at
Ingleside, MD; we are going to add F1P to be flown along with F1J in 5 rounds with F1P
at 10 second engine run, F1J at 7 second engine run; both with 3 minute maxes
weather permitting. All the flyers are out and the sanction is on its way,
so this is a late added event because we have had quite a number of inquiries
to include it.

Effective Use of the Internet for Free Flight Communications
=============================================================
Roger,
In my last posting I pointed to the example of the Stuka Stunt online forum
(http://www.clstunt.com/cgi-bin/dcforum/dcboard.cgi) as an example of
modelers using the internet effectively to communicate and share ideas,
photos, plans and experience. I feel I should add two points to my previous
remarks:
1) I probably gave the incorrect impression that such a forum format is
*required* for effective internet communication. This is certainly not
true. The main problem the keeps being mentioned is that it is not possible
to post large files, pictures, etc. directly to SEN for broadcast
distribution. This is not necessary, or desirable. All that is required to
solve this problem is the use of web pages. Web pages were invented
precisely to address this problem. Rather than tie up large amounts of
bandwidth transmitting large files to many people, the files are posted to a
web page, and the URL (web address) broadcast to those who might be
interested. People are then free to view the information with a web
browser, and download whatever is of interest. Web pages can serve as
online libraries for contributors to post their material for the benefit of
all. Since SCAT has a web page, it should be simple to establish an address
for contributors to send photos, scans, or documents to be posted for all to
read. In addition, many SEN readers probably have access to personal web
page space from their internet service provider. They can post material of
interest to SEN readers directly on their personal pages, and just pass the
URL along to all by sending a short note to SEN. Many of my colleagues on
the US Spacemodeling (rocket) team use this approach.
2) I've stumbled onto the Flitelines Forum (http://www.flightlines.com/)
which is very broad based. What I notice is that there are specialty
sub-forums already established on Flitelines. In particular, there is a
dedicated Control Line forum there. It might be possible to similarly
establish a Free Flight forum on Flitelines. Since the infrastructure is
already in place, the Free Flight community could have a forum available
with a minimum of effort. This is a wheel that does not have to be
re-invented from scratch.
Thermals,
Andrew Tomasch

WONRERFUL BEAR CUP
We had wonderful weather and a nice World Cup contest in Pori Finland
March 6.
Lake Pyhajarvi had more than 50 cm of ice and some 5 - 15 cm of snow on
ice. So we could drive the cars in the middle of the large lake.
All the day with no clouds. The morning was cold, -14 degrees celsius.
When the contest started it had got to -10. Almost no wind. Sun was
burning from the blue skies and reflecting from dazzling white snow. So
nice flying. In the afternoon temperature was close to 0 and wind some 1
- 2 m/s.
Large fly offs.
See the list of 17 juniors! Some of them had problems to run fast enough
in snow.
Here you have links to the large collection of sunny photos.

Interesting engine, howerver I do not use or collect such engines. I'm forwarding to SEN for wider distribution.
Good luck,
