Hi Roger,
at the same date (18.08.2002), but some 2 1/4 hours earlier I got
something I consider a worm or worse.
It had the Reference line "HL Veenendaal3904 HL", no text body, but an
attachment (which I did not open!)
just selecting it made my computer try to access the internet (which I
prohibited).
Looking at the "properties" I found the following:

Allow me to put in my box fuselage, balsa structured, few functioned
ideas, and let me confess that I still use pre-tensioned monofilament
for all functions, even D/T. My trick to get around the
lengthening/shortening of the D/T line is quite simple: The line comes
out of the fuselage in front of the stab, gets a knot plus a crimped
Alu tube (3mm long), and goes back through the fuselage to hold down
the stab. That means, that the stop limiting D/T angle is very close
to the stab, and not in the front of the fuselage. Any variation in
length has a negligible effect.
It does not look nice, however. And will not work for a bunter,
probably. But please do not forget the simple planes!

will like the results. Look forward to seeing everyone again! Mike
Junior F1J at the World Champs-USA Kicks Butt!!
===============================================
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
By now all of you have read what our kids did at the World Champs.
Having never been in a World Champs, John and I really didn't know what
to expect. However, after the first day or two of testing we knew that
we stood a good chance to do well.
John was very concerned about doing well and proving himself to all
those that supported him in attaining a position on the team. We have a
had shaky year in testing, with rain and winds keeping us well behind
the power curve. We never were able to fully test glide any of our
models for more than a minute, so we had no idea what we were capable
of. For information, we had a Vasily 6 panel model, an Oleg Stoev model,
an Oddyssey with our own frontend, and a W Hobbies winged model with our
own fuselage, all powered by Cyclons.
The Korean team showed up with a full team and all new models. They
probably spent thousands of dollars on theior new toys and the team.
John fired up one of his models and launched while their team watched.
After it bunted all we heard was a big "WOW" from them. Then Austin
launched and again, there was an even louder "WOW!!!!" It was pretty
cool.
Austin was by far the highest climbing model on the field, with John
second highest. The Russians and Ukrainians all had engines (most of
them Rexs we think) that turned up higher than we (Austin was taching
28-29K while we were in the low 27K range- we were running 35% and
Gunders tipped the can at 50%- Both with Red Max fuel-they supplied and
shipped the fuel for us- Thanks guys!!!). We smelled allot of castor oil
around the Europeans. Many single bladed props and no gears. The Ukraine
models were very nice, with about 4" more span than us- Russian models
were lower aspect ratio.
First round was 5 minutes with only 5 of us making it- John, Austin, 2
Russians, and 1 Ukrainian. Then followed 4 two minute maxes, with the
same five remaining clean. The only real problem happened in the last
round as Austin was called on an overrun by a timing crew from a
competing country. We clocked Austin at 6.48 sceonds and they got him at
7.7!!! This caused much concern, as Austin was pinching off and the
timer group timed to the very end of the rundown (maybe further).
Ultimately the Gunders ended up running the engine at 5.5 seconds. With
the performance that Austin and Craig has on their 6 panel Oddyssey it
didn't effect them too much, but there still was much concern.
The flying ended at 2 o'clock. The first flyoff round started at 6
o'clock. The first flyoff round was three minutes, with the wind at 5- 7
mph. Everyone made it. The four minute flight saw one Russian dropping
out after a massive bunt lost almost all his altitude. So now we had
four.
The 5 minute flight was the downfall of the other two Europeans as John
and Austin easily made it. We know knew that the USA would be on the top
of the podium!! However, the models had drifted far into corn and near a
small village. This is where the chase team was the heros!!! Jim (Down
Wind Jim) and Dallas Parker, Tom Coussens, Taylor Gunder, Charlie (Mr
Cornfield) Jones, and the entire Avallone cross country team did a
fantastic job of getting the airplanes back in the required time. There
was a time in which there was a three or four man handoff to get the
models back to the flight line. Without these people we never would have
gotten everything done in time. THANKS!!!!
It was now 8 o'clock or so and the CD asked if we wanted to continue.
John and Austin both readily agreed to fly and so it was. They both put
the timers in the bottom groove and fired up. Austin went first and
after the bunt the crowd that had gathered cheered and applauded. John
fired up, launched, bunted, stalled once or twice and started gliding,
again followed by the cheering crowd. After 6 plus minutes they both
maxed and once again the chase crew did their excellent job. John's
model was retrieved, but Austin's went out of sight. The Walston radio
once again proved its value, as Bob Piserchio got a signal and readily
found it. This ended the night, with a very happy USA team.
Saturday morning was going to be the final 10 minute round, starting at
7:00 o'clock. John test fly his Vasily model, with an excellent climb
but the model locked in bunt and glided inverted into the ground,
breaking a wing tip. There now was 10 minutes until the start of the
round. He grabbed onto his number three model (Oleg Stoev) and we rushed
to the flight line, with Austin ready to go. The gun sounded and Austin
launched, again to cheers from the gathered crowd. The model stalled
from it normal high altitude, taking a long time to settle. John found a
minor problem with a line and fixed it. With time running out he fueled
and fired the engine. After a good launch and perfect bunt the model
settled into its glide. Austin's model glided down behind the trees at
6:10 while John's also settled behind the trees at 4:50. Craig and I
celebrated the victory while the kids accepted congratulations from all
around them.
I wish to thank all of you that supported us in this once in a life time
adventure. I could fill up many pages with what took place, but need to
specially applaud the entire team for their support as well as Bob
Gutai, Jim Haught (he lent us a radio, so now we need to get one!) and
Dick Swenson who provided the team with medallions that we handed out to
all the competitiors and supporters. What a deal and look for us in
France in two years!!!
More Junior WC Comments
=======================

With the afterglow of the World Champs still huge, I want to provide a
bit more insight into the excellent job the entire team did in Slovakia.
1.) Everyone that participated on the team jelled into a TEAM. I have
never seen a group of individuals that did what it took to provide its
members with all the assistance they needed. The chasing by all was
fantastic. From "Down Wind Jim" Parker and Tom "I got your Model"
Coussens to the fleet footed Avalones, each person did more than was
expected and made the flyers very confident that they would get their
models back.
2.) Each kid showed professionalism in their performances. Ben Coussens
had the misfortune of breaking his number one airplane minutes before
the first round. He bounced back and performed admirably. John L. (my
son) had his number one model bunt into an inverted glide and break a
tip 10 minutes before the final flyoff. John very calmly rigged his
number three plane and put up a good, pressure packed flight. Ryan Jones
had a front end on his F1B model foul up and the KIDS fixed it, which
allowed him to put up another excellent flight. These kids know what is
going on!
3.) After the awards presentation, John L. and Austin were asked by the
Ukraine team to follow them to their van. We had no idea what was
happening, as it was 500 feet away from us. We saw the entire Ukraine
team surrounding the two and then the team broke out into applause. As
Austin and John walked back, they had been presented a complete F1J
model as well as a set of wings. Eugny from the Ukraine stated that
these models were their present to them. Totally awesome!! These kids
were hard competitors but so gracious.
4.) The Isreal team was awesome. They looked at our models and soaked up
everything they could. There was a time in the hotel when our kids and a
large group got together and talked models for over an hour. It was so
cool to see these kids, a world apart, comunicating about what they
loved.
5.) The Koreans showed up with a full team, with all new models. Yeah,
they did show that they didn't fully understand what to do with them,
but our opinion is that they will be a team to watch. After every
launch, there was at least three Koreans running after their model,
waving and flapping, no matter how good the flight was. If there was an
award for most energentic, they won hands down.
6.) We had the best team there, even if the results didn't show it.
Every kid on the team was a winner in their own right. Tough conditions
in F1A caused problems, as did some misfortune in F1B. In power, what
can I say!!!
7.) Austin Gunder had by far the best models on the field. He climbs
higher than anyone, with John's models second. It seems that we had the
right combination between prop and engine. There were others on the
field that sounded faster, but we had the performance. John's Vasily
designed model had the best glide. It just floated and took everything
it could.
Thanks to everyone throughout the USA that supported the team. Dick
Swenson provided medallions that the team presented to every kid and
many adults. These cost him a bit but worldwide they will be remembered
and treasured. The Russian team was very serious, but one thing I will
remember is the youngest member of their team wearing this prize around
his neck. To everyone else that provided money, your investment was well
used. To see these kids competing against the best in the world is a
source of pride that will not be forgotten.
So, its two years to France and we are looking forward to it. Let's see
if we can get together and kill F1P!! The comments going around the
field was that F1P is not a good thing and we should keep F1J. Austin,
John, and the rest of the US team agree. Thanks again to all and see ya
at the field!!

Calculating Area of Curved Wingtips
===================================
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
When the leading and trailing edges are straight, calculating the area is
easily handled. Finding the area of wings with curved leading and/or
trailing edges has never been easily done. The most accurate way (not
practical at WC checking) is to use a planimeter that travels around the
perimeter which produces a number changeable into area. I used one back in
the 50's when the area rule came into effect for reshaping fuselages to
improve the drag at low supersonic speeds. Another method is to do what is
called a strip integration. This involves laying out the planform of the
wing tip on paper and dividing up the span in perhaps 20 segments. Then the
area of each section is the width times the average length and then summing
the section areas. Of course, the measured area of the tip has to be
adjusted to the projected span divided by the true span. This system works
for leading and trailing edges that area continuously curved in one direction
(no S curves or notches).
I have found a method that is relatively easy to use. It requires the
measurement of the root chord of the curved section (CS) and the chord at 80
percent of the CS span. This is done by measuring the true span of the tip
(using the lower surface is easier). This chord is divided by the root chord
and is called x in the following equation, more easily calculated in MS
Excel.
Area Factor (af) = 0.3365 + x(0.847 + x(-0.1412) +x(-0.0429)))
Then the area of the CS is equal to 2 times the CS root chord times the
projected CS span times the area factor.

Tangent Classic Results
=======================
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
We had the best combination of fields in terms of retreival ease, for as
long as I can remember. Unfortunately, the drift gods did not
cooperate, so we had to move the flight line several times each day to
keep our models out of harms way. No rain and some big thermals made it
an interesting weekend with Mike McKeever achieving the only Max out in
the big F1 classes. It was Mike's first time to our contest and he had
a great weekend, winning F1 A, the Wayne Drake Perpetual Trophy and F1 H
in the Sunday morning fly off. Local boy makes good in the rubber
events with Ralph Cooney winning both F1 B and F1 G and Doug Joyce
taking F1 C. I won F1 J only because Dave P tanked the last round.

Composite structures for hlg
===========================
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
Just received the following email from Len Surtees in Australia. It may be
of some interest to you hlg / clg fliers out there. I confess to having
used a stab that Len has made and it did make a difference as it was wet on
the grass and in the air when I was flying, however, against the balsa, it
held its trim perfectly and failed to warp. The stab was also lighter than
my conventional 1/16 sheet type and for me has to be the way forward to get
as much out of a hlg as I can. If interested - give Len a shout - on:
This email address is being protected from spambots. You need JavaScript enabled to view it.
If you want to chat about hlgs or clgs at all or have some bits that I can
include in my next newsletter for hlg and clg fliers - then drop me a line.
My best wishes
Kevin Moseley - wishing he could get his P30 to behave and a F1B finished!
Hi All
I have been developing over the past several months an alternative to balsa
wood stabs/fins for outdoor hand launch gliders(you know, the ones that dont
hold their trim on wet/damp days).
My composite vacuum bagged tails are compatable to 6lb sealed balsa in
weight, are not affected by water and have a carbon fibre leading edge
reinforcement.
Initially these CVBT were to be offered as a supplement to my STING 18",21"
and 24" OHLG kits but i will now provide custom made CVBT up to 9"(just send
me a profile). By having a CVBT on your glider you will be the center of
attention at your flying field.
Cost is only US $10, AUS $15, UK 5 pounds, (price includes air mail
delivery). DONT LEAVE HOME WITH OUT ONE.
Best Regards
Len Surtees.
Nylon Lines
===========
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
I have in the past also used nylon for DT and bunt lines, and found that on
my bunting F.1.A it would bunt nicely on some days, and then not nose-down
enough on bunt on other days. I found that on warm days the nylon was
stretching enough so that when the tail went down to bunt position, it had
lost around 3mm of the down elevator it needed to bunt properly!
My newer gliders now have dacron D.T lines. I'm also a keen fisherman, and
have looked into the nylon coated wire e.t.c and will probably use that in
the future.
