How can a rigid wing pilot jump over to the flex wing side?
My first flight in Australia this season was the first day of the
Australian Nationals. I had to quickly relearn how to fly a flex wing hang
glider within the first hour of the task, before the start window opened.
Fortunately, I was able in time to retrain my body and go from just shifting the
control frame to shifting myself. Sure it wasn't all that pretty at first, but
it got better as the competitions continued. After a while it is back to being
second nature.
Two things really helped. The first is the fact that I was flying a properly
sized glider. Last year I flew a S4.5, which I found overpowered me. This was
never true this year.
Second, Aleve. Non steroidal
anti-inflammatory. Two in the morning and two in the evening. But no taping
extra Ibuprofens to the base tube as Mikey Barber does, so that he can have a
few in flight.
So I suggest carefully thinking about just what size glider makes sense for you.
Sure there are manufacturer recommended hook-in weights, but check things
out for yourself.

Regrettable to find these pages which are no longer state of the art. The
spinnaker shackle, particularly the one photographed here, is not to be advised
as it doesn't release without tension. The Koch equipment has never failed as
far as I know. The other systems are less reliable (again tension problems).
Two different types of tow releases. One of the quick release type
Robin used (but here as part of the Moyes V-line system), and one more home made
release:

We were able to make the spinnaker shackle hang up with relative
ease. All it took was a twist or two in the weaklink line while putting it on
the shackle. We also got the Linknife to hang up. It took a particular figure-8
wrap with the pull string stuck under the O-ring to do it. Something that would
be highly unlikely to happen, at least with a modicum of due diligence by the
pilot.
This is my closed aerotow V-bridle with Linknife on weaklink at
the bridle/towline junction:
I'm pretty sure that we build one of the few sewn hang glider bridles. It was
designed specifically for those who choose to foot launch hang gliders from the
beach or shoreline. Most of these pilots used the aluminum block dual trigger
style release and didn't want the hunk of metal on their chest. Almost all of
these pilots choose to tow from the hips, with an attachment on either side of
the harness that runs up through the hang loop.
I kept trying to find pictures of the standard glider tow release we used to use
years ago when I towed aerial advertising banners. I did find a line art drawing
of it though.
Essentially the towline went through the space in the L shaped bracket. This
bracket was held closed by tension on the pin created by the semi pyramid shaped
rubber pyramid at the bottom above the pivot pin. A release cable was connected
to the top, and when pulled, the L shaped arm flew back releasing the towline.
It wouldn't take much to whip out a few of these in a lightweight alloy if the
demand existed. I'm not a fan of the spinnaker releases.
(editor's note: More on this type of release in the next issue.)
I have to admit on one occasion a few years ago the weak link got
snagged on the little lip on a typical (Florida style) wishard release at the
end of my tow (after opening/releasing the release). It took more that a few
moments to process the information ("that's odd.... I'm still being towed!
Why??"). (Tug pilot must think I'm an idiot. :-)
I physically shook the bridal, but that didn't un-snag it. I located my hook
knife with my hand, but then just decided to wang hard to break away, which
worked fine. I can see how this situation would really suck, just out of the
cart, or anywhere near the ground.
Since (and before) then, I've had many, many uneventful tows with those
releases, but I concur that a ring would reduce the chances of release failure
significantly.

No matter what type of weaklink material you use on this type of
release (spinnaker shackle), it is only a function of twisting and tension to
make the material become tight enough to not slide off the leg. Try it on yours.
Scary?
In my opinion, the only part that should be in contact with this type of release
must be something that cannot get tight. Use a metal ring, one that is large
enough to come out every time, or use a different release.
(editor's note: Much more coming in the next issue on this.)
The table above gives the top twenty ranked pilots after three
major CIVL sanctioned competitions in Australia including the Worlds. The pilots
are ranked using their best finishes in their best top four meets. All the
European pilots have the Category I European Championship as one of their top
flights. No top twenty pilots outside Europe have points from the European
Championships counting for their ranking.
This chart shows that non European pilots have a chance to rank high when the
Worlds is held outside of Europe. The Europeans have their chances with the
European Championships and don't need to have the Worlds in Europe.
I've moved back to Google as the Oz Report search engine.
The Google search engine indexes over 5000 Oz Report pages now and
is only a couple of days behind the latest issues. It is great to have all the
power of Google behind the Oz Report.

Looks like they will have wired internet access here at the
Plenary, but no wireless. So, I'll be taking some unofficial notes during the
meeting, and will post them to my blog at
http://midtoad.homelinux.org/wp/,
in the 'flying' category.
The Bureau meeting is on right now; that's where they lay out the broad lines of
what they want to get accomplished during the Plenary.
We're stoked that he'll be playing a bigger creative role within the magazine in
the coming months. And as a former World Cup competitor and current rigid hang
glider and paramotor pilot, we are sure his deeply-rooted passion for all
aspects of free flight will translate into an ever more exciting magazine.
Cross Country will be launching a separate new Digital Edition.
The Digital Edition will be available to download, and will include video clips,
audio interviews and interactive advertising to make Cross Country come to life
even more.
Our quality printed edition continues completely unaffected, but we hope the
Digital Edition will make Cross Country's dynamic content even more widely and
readily available. More details soon
