Canada Cup. August 30th. - 31st. 2003
This year's competition was held in great weather and with the
participation of a very strong international group of modellers. To keep
the competitor's energy level high, the traditional goulash was cooked
and served on the field on Saturday. The thermals were so strong that
after DT, it took the models 6 to 8 minutes to come down. This resulted
in the reduction of maxes for the second and third rounds.

New Electronic F1B Model from W-Hobby

Interesting! The battery is 130mAh NiMh? How does it work in cold? In
Finland we need to fly our models down to -20C... Also, what brand of
servos do you use? I've found great differences with different brands when
taken to cold conditions... (So far Hitec HS50 seems to work best for me).

Bungee cords
============
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
At the Canada Cup, over labor day, I asked Alex Adndokov
whether he knew how to get "Hungarian" rubber. It's round,
tan, with a diameter of .045". The rubber is a favorite of
some eastern European builders, with stabs sporting tiny
rubber hooks. (Try to use a number "8" or "10" rubber
band on such stabs). Another usage is to hold the wing's
together. Wakefield and power models have similar
usages.
According to Alex, manufacturing of the Hungarian rubber
has been discontinued for years, and fliers are running out
of the aging stock. Instead, he suggested to consider
the internal rubber chords contained in bungee chords,
provided they are round.
Victor Sokolov gave a short piece of black bungee rubber
chord, 0.045" thick, both strong and flexible. It stretched
by a factor of five with a tension of 1 lbs, measured crudely
by a fishing scale.
The only draw back was the difficultly to tie it into a loop.
I ended up using a series of three consecutive simple
knots which seemed to do the job. Another possibility
is to use a linear piece of rubber, with knots at each
end, anchored into notches on the stab mount.
Back at home I bought a mini bungee chord and
discovered that it contained 38 round rubber chords
in its core. This time they were white, molded in
parallel into a sheet, half as thick - .022", much
weaker but easy to tie. The thinner rubber chords
might be used for lighter weight jobs.
But mining the rubber chords requires some effort,
as bungee chords have a tightly knit (nylon?) outer
cover. It takes a sharp pair of nail scissors to slowly
pry open the protective cover without damaging the
internals.
Since not all bungee chords are created equal, some
probably have higher potential energy storage (as
measured under the torque curve). Since the rubber
chords are as long as the bungee chord that contains
them, they might even be used to power small rubber
models. In short, bungee land is worth investigating!

Hi all.....
Sitting here looking at what was supposed to be rotten weather at Muncie (sunny
and nice- aaahhh!!) and have a request.
I am looking for a good Mk III OS max .15 piston and liner for a project. Anyo

Hi
I just read your story about co2 rockets. I am looking for the piercers
for the co2 cartridges for those rockets. We just made these type of
rockets in me education class out of construction paper and 3 x 5 cards.
they work real well.
Could you tell me wher to get the co2 piercers.

World Championships 2003 - Comments and Opinions
================================================
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
Hello all,
I too would like to take the opportunity and note my agreement with Jim Brooks
(and the many other flyers) who are concerned about the lack of proper
organization at the World Championships in Hungary a few weeks ago.
There were many things which one can criticize, and given that this was such a
large event some of the more minor inconveniences can be overlooked. There
were, however, a few things which I think should have have been
done differently. First of all, I
(as I’m sure a lot of those who flew F1A with me) feel that the F1A rounds
could have been postponed as a result of the rain that plagued our
flights. A spare day was available,
and there really was no need to have us fly in such horrible conditions.
Keep in mind that to most of us our models are worth small fortunes,
and having a few hundred dollars
of miniature electronic mechanisms exposed to water is not too pleasant.
MY second
concern was the lack of water, nutrition, and general “break
time” available to the flyers.
As I remember, all these things were openly available at the last World
Champs in Lost Hills. A determined contestant could have overcome
these difficulties, but it didn’t help
matters that we could not drive up to the start line, and had to drag a
dozen litres of water each day. Third of all, as you all probably
already know, is the problem with the canal.
The field itself was quite large, and even with the canal in place things
could have been easier had the organizors decided to move the
start line to a different location so that
models would not land on the other side of the canal on a regular basis.
Most of us are no longer juniors, and retrieving models caused
huge problems for all, especially those who
were unable to come to the contest with a reserve of supporters. At this
point in time I want to thank all my team-mates for their help in
retrieving my models, which allowed
me to use the same model at least every second round. There were some
smaller issues, but these three stand out as the most ciritical.
I write this now in hope that such inconveniences can be avoided in future
contests, and especially in future World Championships. With a
relatively large entry fee, we should at
least expect these basic. All in all my trip to Hungary was enjoyable
experience (a very nice coutnry with very friendly people), but the
drawbacks of the contest itself, and most
notably the contest organization were clearly visible. Once again, I hope
that by discussing these issues in an open forum, we the modelling
community can come to a general agreement as to what to expect out
of contest, which for all intents and purposes
should be designed for our benefit.
Sincerely,
Chris Lenartowicz (F1A Canada)

Indoor tips
============
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
Do all indoor modellers leave the tips of their F1D ships flat i..e.,
without camber? Or do they introduce camber during the covering process so
as to maximise the lifting ability of the wing? Or does the covering
process camber the tips or,conversely, do the tips camber during flight at
the same time the air pressure lifts the film between the ribs?

Roger,
Re mention of Sirtrack beacons by David Ackery and query by ab.boutillier,
contacted was made with Sirtrack and enquires made. The reply attached
below does not cover all aspects, but may give an indication as to whether
further enquiry is warranted. Note that prices are in NZ dollars - multiply
by 0.526 to convert to Euros.

Hi Bernard
The transmitter featured on our web site is a 2 stage "unpackaged" (IE
conformal coated, no heat shrink, ready for epoxy coating & attaching to a
collar & battery). We can supply them to you in this state ( I would
advise heat shrink, no extra charge). They run off a 3.5 volt cell; of
which there is a great Variety dependant on life & size, and range from
$15.00 to $150.00.
The transmitters are approx 20mm (or 15mm with folded crystal) x 10mm x
5mm, & weighs 2 grams. Cost $160.00 (unpackaged). Depending on what you
want, we can epoxy them including battery & aerial; cost depends on what
you order.
Ground to ground transmission you could expect up to 2 kms, & air to ground
up to 15kms. Caution! Terrain, environment, weather & temperature can all
have a negative or positive effect on these figures
We can supply any frequency you want, but for NZ, we normally supply
160/161 MHZ in 10 MHZ spacing.
Aerial length is up to you, specify the length you want & we will tune the
transmitter to that.
For reception, most of our wildlife customers use a telonics TR 4, it is
rugged, reliable, easy to use & very portable, pig dog hunters tend to use
an ATS Fieldmaster, it is a bit more bulky, but performs very well;- with a
3 element folding yagi.
A TR 4 is $1780.00, Fieldmaster $1280.00 3 element folding yagi
$272.00
Hope this answers most of your questions
Regards Phil
