to Table of Contentsto next topic Easier to manage waypoints

record|Ron Henderson

Seeyou (http://www.seeyou.ws/dload.shtml) and G7toWin (http://members.home.net/crh24/gps/g7towin/g7towin.htm) have been updated to make it easier to manage turnpoints with the Garmin GPS.  You can create turnpoints with Seeyou's powerful mapping technology, and then read them into Garmin GPS's using G7toWin.  Seeyou makes it easy to create FAI triangles graphically.

I use Seeyou all the time to display IGC files, which record my flights.  G7toWin is a powerful free waypoint and tracklog management program for the Garmin (and other GPSes) and it is updated all the time with increased capabilities (unlike Waypoint+).

I have a great time interacting with the Slovenian programmers/pilots who have created Seeyou.  They write:

G7ToWin is a very nice software for interfacing your Garmin to your PC. Immediately after downloading tracks from Garmin you can choose File->Save as IGC track and create a faultless IGC flight file which you can easily open with SeeYou.

Additionally Ron Henderson, author of G7ToWin has decided to support SeeYou Waypoint format (.cup). Which means that you can use SeeYou to graphically prepare your Waypoints database, save it in SeeYou .cup format and then send it to your Garmin through G7ToWin.

Responding to the demanding environment of top class competition the Moyes team have produced the new low drag "Zoom" control frame, giving a significant drag reduction over the standard control frame and meeting the latest structural definitions of the FAI.

 

Selected pilots at the World Championships have already tested the "Zoom" frame.

The aluminum downtube section is based on the carbon ones used by Gerolf Heinrichs.  This gives minimum drag over a range of angles of attack.  Downtubes are produced as an economic Aluminium extrusion with an internal strengthening web.  Finish is superior black powder coating to match the base bar.

 

The Zoom base bar comes in mirror finish carbon fibre with the Moyes logo inlaid in the top laminate.  The A-frame geometry reproduces the grip position of the standard base bar and FAST bar with comfortable grip sections.  This means pilots can swap to the new control frame and feel comfortable straight away without any modification to hang height or harness position.

The whole control frame has been designed using state of the art 3D CAD solid modeling techniques.  The intersection between base bar and downtube has been developed to give precisely the correct incidence angles for minimum drag and even the pip pins have been reworked so as not to disrupt the airflow.  CAD designer Attila Bertok claims these avoid drag inducing incidence errors between the downtube and base bar, a fault of other designs produced with aesthetics in mind rather than aerodynamics.  The Zoom frame corners are produced by precision investment casting finished with a durable black epoxy powder coating.  The Zoom frame has been designed with careful thought to ease of rigging, no tools are necessary and takes no more effort than a standard control frame.

 

VG operation has been improved over the standard control frame with the use of free running ball bearing pulleys throughout.  This has enabled a reduced gear ratio to be used for the same pilot effort - so VG is applied with fewer pulls and there is less drag inducing rope projecting at full VG.

The Zoom control frame fits directly to Litespeed gliders in a few minutes using the same rigging wires and heart bolt and can be adapted to any current glider much easier than other contemporary control frames.

to Table of Contentsto next topic Loving the WW ATOS control frame

Flew with it today.  It felt great.  I thought that I wouldn't like the wider grip area, but it was not an issue (but then there wasn't any turbulence). It felt like it sliced through the air.

I haven't had a chance to fly next to Johann in his new ATOS with the AIR control frame.  When I'll do I'll see if there is a difference.

to Table of Contentsto next topic Such nice cloud streets

They have such nice cloud streets here in Hearne.  This morning they started at 8:35 AM again and stayed until at least 2 PM. The air was a little drier up higher than two days ago, so really long flights were more problematic.

The clouds got really thick and it almost turned dark.  When it broke up a bit I could count six streets that due to parallax all seemed to be coming from one single point.  They were incredibly well defined.  There seemed to be no problems with launching at 9 AM and staying under them.

As this was the day before the nationals it was hard to think about getting out there early and going for a 300 miler.  I finally got off at 10:45 AM and the conditions were perfect.  Light plentiful lift or lack of sink under the continuous cloud streets.

Between 11 AM and 12:10 PM I flew straight for 80% of the time (55 minutes). I averaged 43 mph, and 50 mph over the ground while flying straight.  My glide radio was 50/1 while flying straight.  The wind was about 15 mph out of the southwest.

Here's a snapshot look at 15 minutes of flying straight under the cloud street.  The top horizontal black line is 2,800' AGL and the bottom line is 2,000' AGL.

Gaye and Steve got the City of Hearne to put in a row of concrete pads with electricity for trailers here at the airport.  They are right on the entrance road next to the hangars and next to the airport office.

We're in number 3. JZ and Amy are in number 1, and Jim Lee in number 2.

In number four you'll find a rented trailer with Carlos Bessa, top Wallaby Ranch tug pilot, Peter Welch, Curt Warren, Sugarman and Valerie.  It is a Wallaby Ranch reunion and we are having a great time.

I have been disconnected from the Internet for the past month or two (Walden Pond, 2001) and have been enjoying the peace and quiet.  Even so, I intend to reconnect soon and would like to write some about the experiences at the Zapata World Record Encampment.  Hopefully, this will serve to encourage those interested in flying long and flying far.

In the mean time, I would like to reiterate special thanks to Dutcher Sterling and Ron Gleason for their generous support of the event.  Even though neither pilot was able to attend, their donations served to transition from last year's exploratory venture to this year's more comprehensive activities.  This also allowed us to combine donated funds with additional donated services and to give significant value back to the airport facility which so nicely accommodated the event, helping to ensure future activities.

Thanks guys!  You have a full share in the world class accomplishments and records, which came out of all of this.

Brett Snellgrove|Davis Straub|George Ferris|USHGA

Brett Snellgrove writes:

Regarding George Ferris' unfortunate accident there are a few points that need clarification.  The protrusion of the cervical disc onto his spinal cord is certainly a serious situation that warrants immediate surgical intervention.  Pilots using the simple Babinski procedure can test this in the field.  Run a pen firmly under the foot from heel to toe, if the toes fan out rather than curl under, the chord could be compromised.

Secondly, a posterior approach to surgery is almost never used for cervical disc protrusions impinging on the spinal cord as the disc cannot be accessed in this manner without removing a large amount of bone structure that stabilizes the spine.  Typically, an anterior approach is used, the disc is partially removed, and a wedge block of bone positioned in the disc space to fuse the segment (anterior interbody cervical fusion after Robinson and Cloward).

Additional instrumentation may be used to stabilize any bone fractures.  A more recent procedure uses a titanium cage, with bone and marrow fragments inside to fuse the spine, and is screwed into the disc space.  It is a superior technique in the hands of a skilled and trained surgeon however failure rates resulting in pseudo arthrodesis (false bone fusion) have been higher than with other techniques.  (The use of bone growth factors appear to improve this problem.) This is probably the procedure George describes.
