Online Registration
===================
We have hopefulyy fixed the online registration so that it
shows more helpful messsages as to why it fails.
The two most commen reasons for failure are - your
name is already registered. If you want to chnage
you e-mail address send and e-mail to This email address is being protected from spambots. You need JavaScript enabled to view it.
to do that.
The second is the use of accented characters as used by
many European languages. Do not use accented characters.
The software we use will not take them and I do not have a way of
changing that.

Heres my notes - apologies are long winded but I dearly love the sport and
I hope it shows -
Arrived at the airfield around 09.30 and found that our position had been
moved around 90 degrees from the previous day with the wind now coming from
the back of the hanger. First impression after driving in and knowing that
it was FAI day was that numbers would be down in the FAI classes as there
was a strong wind blowing and it was hard to distinguish from lift and the
wind on the streamers. I drove up the flight line and back acknowledging
the good mornings and looking for the box . I located this half on the run
way and half off which is sensible if you are sure of your ability to launch
and not end up with a model in bits on the asphalt surface. As I parked up,
I carried out my usual routine – coffee, sit and watch and take in the
atmosphere and listen to the cacophony of noise of wind breaks being
hammered in to prevent the models being damaged. Coffee completed, I dug
out my pole and streamer and walked a good maybe 50 meters from the car and
hammered the spike into the hardened earth. I put up about 20 meters of
streamer and as soon as I had let go of the end, this was whipped up high in
the air ad out of reach. Not a good sign in the strong wind. From here I
brought out my tool box complete with a tent thing I have and use as a
shelter and windbreak as well as a couple of large bottles of water and four
gliders. I had with me three STING24’s and a STING 30 on the off chance
that the wind may drop and I may benefit from a superior glide from a larger
spanned model. Arriving outside the box, I set this lot up, placed the
models back in for safe keeping and keeping them out of the wild wind.
Len Surtees had already arrived with Mark Benns as well as Bjorn and Martin
from Sweden were stood talking. There was plenty of space in the wind break
and I invited anyone that needed it to make use.
The wind was blowing strong and suddenly, we had a massive blue sky, no
cloud at all and a warm sun, the strength of the wind keeping the
temperature down nicely.
I watched as Kevin Tatlow arrived with his 2Kan model and settled down to
get comfortable. The next to arrive was Mike Chapman, then the Clarks
followed closely by Mick Page who looked his usual self and ready to cream
us all. I have yet to see that man not smile! Unfortunately, for Mick, the
day was going from bad to worse and the natural problems associated with
getting a good glider on trim in heavy wind was becoming impossible.
I started re-trimming the 24 model that I had been getting somewhere with
last night and hoping that nothing had altered from yesterday. I got the
trim perfect in my mind with a very smooth transition and roll out turning
quickly into a left turn and away, however, due to the location of the box
and the low level turbulence from the hanger and trees in the distance, this
was now causing me problems.
I began to think about comp flights and when I was ready, there were quite a
few of us stood in the box waiting and watching the streamer for any sign of
decent air. Whilst in the sun, the wind was measured at 30mph, however, it
was cool in the sun and I would occasionally twist and keep the arm and
shoulder moving so the muscles would not forget what they were about to do.
I wanted a final trimming flight before I started and for one brief moment
and it was incredibly brief, the streamer dropped and the air temperature
went up. No one was flying so I raced between Mark Benns and Mike Chapman
and launched. It looked like my efforts trimming were worth while as it
climbed on rails, transitioned high and began to climb. I stood there and
then saw Mark heading towards me and with that his glider was away and
chasing mine for his first comp flight.
For around 40 seconds Mark and my model shared the same air with my dt
kicking in at 40 seconds very high, however, Mark was away for his first
flight and first max of the day.
I returned from a long walk down wind and Mark followed a while later both
of us happy although my flight was not a comp one at all. Mark thanked me
for picking him some decent air and I was thrilled to see his first flight
go so well and knowing I had helped in a small way felt even better.
Len pulled out one of his STING 18 models and his throw was incredibly high
and the transition was perfect. We all marvelled at the height and on a
flat calm day, that model would have maxed from its altitude with ease. Len
had four flights on his card before I had one, however, there was a problem
and Len knew it as a warp had crept in on the right wing and was causing an
uncharacteristic spiral in from height. A visit to the model box and a new
model was used and again, it climbed on rails and handled the wind better
than most of us. Maybe the answer was to use a smaller spanned model and
the 18 was ideal.
As the day wore on, again, the hlg box became a hive of activity and was
generating a lot of interest and with it came some of the fliers from the
previous day. We had a long period of time when we stood waiting with
models ready whilst people with cameras were clicking away avidly. I hope
anything that they took came out and they are able to use them to publicise
hlg for us and promote the class.
It did get warmer by lunch as the wind got stronger and the wind breaks were
being buffeted around quite a bit. No one was really interested in food
though as flying was too important to us.
As far as the camaraderie was concerned, this was carried from the day
before and intensified even more so if not magnified. The amount of periods
laughing were lengthening as we watched the streamers and never once, did I
hear a harsh word spoken or a voice raised unless to talk to someone above
the wind.
We wished every flight of everyone to max and sometimes we were lucky, a
good flight was above 40 seconds, under it, it became a victim of the
turbulence.
The Clark family were camped over to the right of the box and again, Ivan
and his dad and the lads who I had not seen for10 years were having a great
day. They flew and flew all day and were a credit to the family.
We were joined by our new friend Peter Tolhurst who had joined us the
previous day and now spent the full day with us. From yesterday and his
exploits with his clg, he was now fast learning the class. He also brought
his son with him and he was as interested as the rest of us as we helped
Peter fly. Again, another young man a credit to his parents and I hope that
we may see them both again soon. Peter’s efforts trimming were rewarded
with some excellent flights and all of us were thrilled by the flights as we
wished each comp flight to be a great one.
At one point as the day moved in we had approximately 30 people in the box
or around it and there were I believe 22 people flying. There were periods
when we had more fliers than time keepers and that is a terrific feeling to
me. It just makes life hard when everyone wants to go at once!
When we did get a few away at once, it was exhilarating to see so many
models in the air at once, albeit in temperamental air.
My best flights with the model were well away, one came down at 54 seconds
and another that was well up – well the dt kicked in early and she was down
at 22 seconds. Had I had the chance, I could have kicked myself! It was
through my own stupidity that I had been so busy watching the streamer, I
neglected the reset the timer!, well, we have all done these things – no?
Phil Ball arrived around 17.00 and proceeded to start flying as quickly as
possible. He did not have a lot of time as he was in the F1C fly off. One
trimming flight showed us that he had a glider to beat as this coped
brilliantly with the turbulence. Unfortunately, due to a dt failure Phil
was last seen heading down wind and I am unsure if his model came down as
was in great air.
The contest ended at 18.00 and we all packed up and made our weary way back
to the control to put our scores in. I got back to the car and began
packing up ready for the drive home and back up north. I was exhausted and
was getting a lot of head pain on the top of the scalp. I was stunned to
find that I had been led into a feeling of false security of being in a 30
mph wind that was cool, only to get quite nastily sun and wind burnt. I
should have realised that it was warm as I drank about four litres of water
and cannot recall stopping once in the day as it had to be sweated out. Be
warned!
I took all the results down an I left to say good bye to dear friends and
fellow fliers, of whose names I wont forget.
I don’t think, as I drove home, that I ever stopped smiling at how the
weekend had been run nor the contest I had flown in. looking back there was
some good flying, good weather, but more so the company that hlg fliers and
clg fliers make was worth more than any flight I made.
My congratulations to the winners, but more so, thanks for the greatest
memories.

Hi Anthony!,
The flux gate compass is not accurate enough for our use as you have found.
The Garmin Summit manual claims +/- 5 degrees accuracy. You need to use a
magnetic sighting compass and then project the waypoint you sighted from.
The Summit will let you do this. Press the enter button and hold it until
the mark waypoint page appears - release and press enter to confirm.
Select the waypoint you have just marked via the waypoint page and
'project' is one of the options. Enter a distance - further than the model
and the magnetic compass bearing - select go to and a line to the model
appears on the map page. The method of using 'sight and go' with your
magnetic compass is a good too - this gives a waypoint 10 units away. The
extra expense of the Summit may not be worth it. Look at the Garmin geko
201 and the basi eTrex as well.
All the above and more is explained in great detail in the Free Flight
Forum Report that Martin DIlly will be happy to sell you.
Sorry if we are boring the non GPS users!

Windburn - wind and sunburn hurts like nothing else I know at the moment.
Whilst flying on sunday at the UK nats, I was in the sun all day, however,
with a wind at times going over 30 mph, I did not feel any heat at all and
the sun was not even a warm distraction. The sky was cloudless and the only
time I was hot was when I was walking back from having a flight with a hlg.
However, on Sunday evening, as I headed home, I first felt it and felt it
bad. As I have had my hair cut short (short enough for Len Surtees to not
immediately recognise me!), I have today started to blister on my forehead
and the top as well as into the hair area that I have. To say its pain ful
is an understatement - its agony and its causing me a lot of sleepless
nights this week. This despite copius amounts of aftersun.
Please dont forget a hat when out and take it from me, a burnt and blistered
forehead and top is not fun at all and even if it does not feel hot and the
wind is up - you can get burnt as I testify. Get some high sfp cream and
keep laying it on. It may be wet and uncomfortable for a while but it beats
what I am going through at the moment.
keep em in thermals and keep covered.

eTrex Summit
=============
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
Mr SCAT,
The comments in the last SEN on the use of the Garmin
eTrex Summit for setting retrieval bearings are
correct. As a user of this device I can confirm that
the use of the internal compass is not recommended due
to it's poor accuracy. I have used the sighting marks
on the GPS but got some good and some poor tracks. As a
result I now use a Suunto KB20 to get the bearing and
rotate the GPS to input this into the 'Sight and Go'
option. This way I get good results although recent
flights have found a large plastic bag and pooper
scooper more use than a method of tracking models for
long distances.
Thanks again for an opportunity to blatently plug the
latest Free Flight Forum report. As well as the superb
article on GPS use which gives more details on the
method decribed above, there is a cracking paper on
jigs which I can highly recommend.

Apologies its a little long - but I hope you feel a little of the brilliant
atmosphere that I experienced last weekend at the UK nats flying clg - Will
do hlg in next few days but it was great and I could not have had a better
day in better company had I dreamed of it.
Keep in touch and keep em in thermals and keep flying hlg and clg free

Saturday – Clg
Arrived at Barkston around 11.00 after calling in at my bed and breakfast
establishment and checking in as well as the room. Found the warmth of the
hospitality and friendliness to my liking in an old farm house dating back
to 1851.
Parked a good way down the flight line after spotting the clg box. It was
windy and raining on and off steadily, however, there did seem to be good
periods of calm spots in the breaks.
First person I saw was Martin Larrson from Sweden returning back to his car
with his flight card and who had stayed the night previously with me. He
returned to the box within a few minutes and I was met then by Mark Benns
who promptly welcomed me, shaking my hand and slapping me on the back as if
we had known each other for years and years. (you meet the nicest people
flying) I spent the next half hour or so stood chatting and watching as
Bjorn and Martin flew their clg models. The models are very simple in
structure and I believe are Martins design but they are potent in the climb.
I was astonished by the way Martin’s model climbed and flew and it climbed
faster than any other model I had ever seen. I was not surprised that the
glide surpassed the climb as it rode the weakest lift in a wonderful
fashion. It made me promise that I would definitely build one very soon.
Mark, in the mean time was having a good time trimming a new clg with his
best in the car waiting patiently to be flown. He wanted, I believe an
extra model in case he had the same occurrence as happened at Church Fenton
a year ago when a model dt’d but still went oos.
As we stood around chatting and flying we waited eagerly our good friend
from Australia, Len Surtees to arrive. He was due in around 10.30 at
Heathrow, we learnt he had arrived ok and had raced across London with a
case and box of hlgs in hand and sat on a train at Kings Cross. He was
still sat there an hour later due to an incident on the line although what I
have no idea. So we continued to stand around, laugh and joke and generally
enjoy each others company whilst my mobile rang every now and then with my
wife updating Mark and I with the football scores.
Martin and Bjorn were posting flights consistently and I watched martins
first flight dt at 1.47 still high on the field and still high up. I told
you the glide was incredible. He was gone an age and we did not see him for
a good while as he searched downwind.
I dug out my STING 18 model and started a desperate attempt to trim it in
the afternoon cold air and drizzle. I hoped that tomorrow would be a little
kinder, maybe the sun out, flat calm, no wind and a blue sky – then again
just a few of them would be nice as alternatives to what we had at that
moment. However, the wind was picking up in strength and so I went over to
the control and picked up my card. John Barker handled the details of
getting me entered quickly and his usual efficient self and I felt the
peasure mine to have met up with him again and I headed back to the car, had
a brief coffee and then back to the box.
Upon my arrival the numbers had now swollen to 7. clgs started going
skyward and this in turn seemed to generate interest amongst fliers from
other disciplines as they walked past after retrieving their respective
models from other contests being hard fought. How nice it was to see those
new faces coming in for a chat and a look at the models. May be we are
inspiring people to come and join us after all.
The afternoon started to ware on and Mark put his first and excellent max
in, Martin duly followed with a 2nd which was great to see. And as the
flights went on, the chatting turned to a lot of laughing and for minutes at
a time my ribs hurt with the strain of the humor. More and more fliers
joined us and the camaraderie became intense as each flight was eagerly
watched and everyone wanted each others model to do well. We were soon
joined by some young lads who were flying their Zing Wings which were great
to see as they flew and flew and flew.
Mick Page and Len finally arrived around 14.30 and the group swelled in
number even moreso. Len opened his box and dug out a STING 18, loaded up
the rubber on the launcher and sent the model incredibly high on a test
flight. The COOL tube brought the model down safely shortly after what
would have been a certain max. some of us who were spending ages trimming
our models could not believe it as a model that had just flown from
Australia was brought out of the box, assembled and then put into air and a
certain max. Kinda sickens you – no? He made up for it and promptly flew
his first comp flight and picked up where the trimming flight had left off
and maxed with ease. The larger chord of the model gave it a lower sink rate
than the 16 inch models and the glide was as good as Bjorns and Martin’s
models.
Mark flew his model in certain max air and away it went in air for a
comfortable max, he was running after it when suddenly, it dt’d and all our
hearts dropped into our mouths as the model fell out of the sky. He was as
we were, heart broken. It seemed that he was that busy watching the air
that he failed to set the dt longer and it had started running as he waited
to fly. It happens and he lives to fly another day.
My first flight with the 18 model went away well enough and transitioned
well, however, the air was not brilliant higher up and it fell out of the
thermal spiralling in. It found the only small patch of concrete in the
middle of the field and this held no mercy on the nose section snapping it
awkwardly. The nose destroyed and not prepared to try and repair it, I
retired the airplane and thinking that it was the only model with a hook I
had, I would not bother flying the rest of the day, take in the ambience of
the occasion. Sitting in the car and watching the rain fall, I remembered
that I had the clg “Lets Roll” - plan on the wind and waves web site by John
O Sullivan - in the car that I had been using for a postal event on going in
Newfoundland. The model is only 8 inches in span but it climbs brilliantly
and I wanted to continue to support the event that I have asked to be on at
the nats and in the UK for long enough. The rain stopped and so I took the
model out and knowing my chances were now nil against the others models, I
was just determined to enjoy it all. If nothing it would be the possible
smallest clg used in a NATS competition and if it gave us a smile – it would
be worth it.
It was all going well for the others flying and chatting and laughing (can
you believe we were actually flying against each other as I could not ?)
until Mark launched and his model came down on a metal grill on a sort of
radar thing. It was nose in and was not behaving. A lot of help with a
fishing pole and a length of string and finally the wing parted company and
we finally got the fuz off the top. The model would not fly again that day,
however, it looks as though Mark may have found a new hobby in fly fishing!
Len dropped his next flight and was down in 22 seconds – a few thousand
miles flight and a 22 second flight – no wonder he looked a little
despondent but was smiling as usual.
The box was at last as I had always wanted it – it was packed with people
either studying the air or the models or flying them or stood around
watching it all. I have never seen so many people enjoying themselves in an
enclosed space and all were enjoying it immensely. For me trying to promote
the class a little, it was in a way moving to see.
At one point I counted over 27 people there including our guests from now
France, Sweden, Australia as well as from all corners of the UK and this
included an occasional patient wife stood there- you just have to love them
for respecting what we do and supporting us dont you?. It made it a truly
international event and a pleasure to be part of and the box held an
incredible buzz of excitement.
Of another note was the amount of youngsters in the box flying. One young
chap, wherever, he launched from, his model always made a pointed direction
straight for me and I ended up running. One point in the box I was stood
there and he had launched off to my left. He was no where near me so I
stood my ground. Something in my head made me take a step back and as I did
so, where I had been stood ploughed in the model with its bright green tips.
One other occasion I was down wind and same again, out of the whole field
this model aimed for me and kept on coming. The problem was that the lad
flying it was not getting enough pull on the loop of rubber and it was not
getting high enough to do anything with. Walking back with him, we called
in at my car and a new length of TAN 2 later, he went off and launched. This
time the model got some serious height and leaped out of his hands and shot
skywards – given that it went higher- a hell of a lot higher - he was over
the moon - it missed me for the first time and he was thrilled. I was just
as pleased for him as that bit of rubber saved me from a certain injury!
The rain kicked in again and I raced back to the car just to come back out a
few minutes later having stopped, this time armed with a hlg that I intended
to trim. This started behaving itself and the omens started looking better
for the following day for me.
The end of the contest came and we all headed back to put in our scores and
the merry banter came to a slow end. I had a coffee and a sandwich as did
not want to head back to the bed and breakfast yet and tidied up the car. I
then moved it down the line of cars to where Mark and Len were stood to find
that Mark had tied with John Barker for 2nd place. I grabbed a watch and
walked back out as it was cold and windy and we all went back to the box.
We all agreed it was cold and could this not be ended in a gentlemanly way –
to get us back to the warmth of the cars quicker. Say – pistols at 20
paces!
I stood with John who was flying a nice T tailed configuration model and
chatted away eagerly as a small crowd gathered with us. I agreed I would
time for John and as we chatted – the wind dropped for what must have been a
second. From behind there was a whoosh sound and to our amazement, we found
that Mark had gone and the model was screaming its way skyards. Even more
amazing than the fact that the wind had dropped for a second was that the
model was climbing in lift. John launched shortly afterwards and I regret
that was down in 31 seconds whilst Marks model was some where in the missile
compound and he was still chasing it! Mark 2nd and John 3rd and I was
thrilled for them both.
The winner of the event, Phil Ball had turned up later in the day and flown
in about the last hour and started putting in excellent and steady flights
with his Catapulticus model. He had been flying all day I believe in Open
Rubber etc and his flights deserved the success. The plan of the model was
in Model Flyer I believe in Apr 2002. It out flew and out glided us all and
is worth building for definate.
I walked back with John after retrieving his model and complimented him on
the handling of the day and that of the assistance of the other helpers in
the control tent.
Entries in clg alone were 25 which is incredible of whom 16 posted scores
which is terrific. I believe that the amount of interest shown in the class
and the realisation of its simplicity in design can only make it larger and
larger. More would have flown I believe had the sun come out.
It has made people realise that you don’t need massive arms to pull back a
length of rubber and send a model towards the heavens. It is a great class
and gives a little more diversity as we all get on in years and an extra
class to turn our hands to.
It was a brilliant atmosphere all day in and out of the box and this was
made even more special by seeing Ivan Clarke and his family again after 10
years of absence from the field as well as Peter Tolhurst who had just flown
his first competition ever.
I can only hope that the event gets bigger and better in the UK and
worldwide and if there is anything I can do to ensure its survival – let me
know.
I left the field that night to spend a quiet and lonely night in the bed and
breakfast and wondering how my wife and son were. So glad mobile phones
were invented!
Results as follows and what a day – what an atmosphere, what a pleasure to
spend the day with the best sort of people I know. Long may it continue and
please join us next time.

Garman Summit GPS

I have been using my eTrex Summit for two full seasons and I am delighted with
the results. Martin Cowley showed me his eTrex Summit at the King Orange meet
a few years ago and I was sold on the spot. I have experienced compass errors
as reported and I have found that performing the "two turn" calibration at the
start of the day solves the problem. It seems that this needs to be performed
if the unit has been out of use for several weeks. The other compass problem i
s it is effected by the steel of the chase bike. This is also a problem with n
ormal magnetic compasses. Simply stepping away from the trusty old Honda solve
s the problem.
I usually find the model less than 50 feet off of the line.

Compass error
=============
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
If you use a "simple" electronic compass (like the one in the Garmin)
be aware of the extreme sensitivity of the unit to be held
horizontally! Try it out by holding the unit at waist level and -
without turning to a new direction - rotating it lengthwise and/or
crosswise. Depending on wether you have been pointing North/South (no
change) or East/West (max change) you will be able to get nearly any
reading you like ...
Simple reason: the magnetic flux lines enter the earth at an angle,
and these electronic things are just too sensitive.
High-level electronic compasses have a set of 3 "flux gates" and can
thus compensate a bit, but still rely on a horizontal positioning of
the unit for precise results. They are mainly made to be used on boats
where you have a clean, level horizont.
BTW: even simple magnetic compasses have this property, but are not as
sensitive and do not work anyway if tipped too far ...
Look into any pilot's teaching book to get graphic explanations of
this property of magnetic compasses.

Might have been a _very nice_ weekend with a double Worldcup if the
wind had played along - so it was just nice: large grass-covered
airfield good enough for 5min flights even on the prevailing windspeed
(6 to 8m/s gusting to 10), clever organizers, timekeepers, hotel
immediately at the field, mostly sunshine (except for a short shower
during the Estonian cup, and heavy rain for their glider fly-off).
Top results:
Baltic Cup (5 rounds only due to wind)
F1A: 1. Kimmo Kulmakko (FIN) 900+300
2. Dirk Halbmeier (GER) 900+285
3. Platko Siarhei (BLR) 883
F1B: 1. Laurynas Gircys (LTU) 885
2. Virginijus Ivancikas (LTU) 869
3. Renaldas Seinauskas (LTU) 868
(1. and 3. are youths!)
F1C: 1. Robertas Seinauskas (LTU) 900
2. Juri Roots (EST) 842
3. Arunas Grasys (LTU) 805
Estonian Cup (7 rounds, no supermax)
F1A: 1. Sigitas Jakutis (LTU) 1260+300+273
2. Evgeny Kantipaylo (UKR) 1260+300+189
3. Gundars Abolins (LAT) 1260+173
F1B: 1. Tapio Linkosalo (FIN) 1260
2. Sergiy Molchanov (UKR) 1233
3. Klaus W. Salzer (AUT) 1219
F1C: 1. Claus Gretter (GER) 1258

Does anyone know if there are any Jim Walker Fireballs available?
I am aware of the one currently on eBay.
Thanks
Low A/rs

Does anyone have a formula for calculating the Neutral Point for low aspect
ratios, please? Most the currently available use the relation between the
aspect ratios of the wing and stab but the wing A/Rs only go down to about 8
whereas I am looking for info on wing A/Rs of 3 to 4 to 5 but more biased to
the lower number.
What do the indoor fliers(F1D for example) use? Or is it just trila and
error, or the currnet state of useage? What i would like is a simple to use
formula(and simple to poricure the measurements for) if that is possible. I
have been using for years a fine little formula derived by Jean Wantzbiether
in France but its wing A/R only goes down to 8.
Any help?
