Randy! Have you been smoking my secret stash again? :wee: Interesting to see a close-up first person view of your local strip. It looks pretty tight
tho. Keep 'em coming.

Guilty as charged.
The pavement strip is wide enough to turn, but there is the narrow part in the middle. I worry about getting a kite line snagged on the fence or
something there. The lake side is pretty narrow. On the south end it is not possible to complete a turn w/o going into the soft sand. On the north
side, the ground is fairly hard, but there are a lot or rocks and pebbles, to deal with. It is very dependent on the wind direction - due east works
best. If there is much north in it, it becomes a one way street (N to S). However, there is a parking lot for the boat ramp that I've used in the
past, but it is usually only available in the winter months (or rainy days) when no one comes to the lake. I used to only ride in the big parking lot
- lately I haven't even tried there unless the beach side doesn't work.
Now that most of the trees are gone, I'll probably try some longer lines, on the beach at least. Also - looking into using kites with better upwind
than NPWs.
I will never complain about my location again. :D I guess we make the best of what we have. I say pffff to those dry lakes and broad endless beaches.
Have you considered using a kite powered watercraft?

I've sailed a PL Monohull kite boat here with some success, but the few launches we have are difficult due to to tall trees, wind shadow and are
highly dependent on water levels. Windstruck has bought my kiteboat and we are working out how to ship the boat. I windfoil in the warmer weather
months, so kitebuggy is my cold weather alternative.
Finally got out again at Garry Point, Nice smooth 12-15mph winds for a couple hrs straight. Small park with people/pylons around so you can't really
open it up there, but it's still good to get out and put a few miles on the buggy.
GP hasn't really been popular in quite a while, The core group all sort of went their own way and it hasn't been the same since. Plus side, it seems
the Oregon group has sort of adopted us.
Rules and regulations make it harder to fly at GP, those of us that still kite usually end up out on the sand flats at Mud Bay or one of the other
beach spots. GP is a small park, and by that it's approx 1/4 km by 1/2 km of usable land, and your sharing it with the other park users. The wind
there though is the best on dry land in the area by far. Next time I am out there I'll try and remember to bring my camera with me and get some
footage.
Today I rode my 9m A15 for 30min then my 8m Genesis for 30min, interesting to ride similar kites back to back. Was on a Haize landboard, blowing
15mph gusting 20+ with some 10mph lulls. Had to stop a couple times and both kites in gusts lifted my 200#s off the ground.
I've modified both kites with the "Jackomixer" modification that has the steering lines connected to C-Lines and Z's get pulled half of C. This
greatly improves turning and quickens depower.....
Thanks for mentioning this PistolPete. Today I modified my Genesis 3 to the Jackomixer. Found this video very helpful. Seems simple enough and
didn't take that long.

that crops up in such situations.
I'm nerding out on the various pulley configurations and the physics of these geometries. I did not know until reading this that folks played with the
pulley geometry like this but of course in retrospect this makes perfect sense.
What are folks attempting to achieve in this exercise? Perhaps I'm biasing myself as my main buggy experience these days is rare trips to Ivanpah
where one has extremely long tack lines. At least for me, bar pressure is a key factor and I prefer low bar pressure. I appreciate that affecting bar
throw length will change the amount of work the bar can "lift" as it goes from out to in, but what are folks trying to achieve? A brief primer would
surely be appreciated!
My circumstances couldn't be more different from Ivanpah. Mine is a small field with erratic winds. I'm looking for rapid turning and an aggressive
power stroke.
Windstruck, I know enough about mixers and bridle trimming to be dangerous. The caveat being I know alot more about paragliders than kites.
For the 3 mixers in Pete's post, the "original" 4-2-1 is the defacto mixer you will see on 90% of kites and paragliders. If all the line attachments
on the kite are at the same distance, it acts like pulling some brake on a fixed bridle. This usually speeds up turning by adding drag and increasing
the max lift by a small amount from the added camber. The effect's magnitude can be altered by changing the spacing between the C and Z lines.
The malabar is a clever way to get the effect of a pulley bar without a pulley bar on the original setup.
The Jockov 3-2-1 removes the brake effect from the mixer. This can be a good or bad thing depending on canopy and what you want to use the kite for.
It will probably make the upwind better, and have less hang back at the expense of turn speed and 'pop' when you pull in the bar.
The spacing between the line attachments and how that changes between from the center to tip of the kite will have a huge effect as well and is hard
to quantify. I know flysurfer (and probably other brands as well) use limit lines in the mixer to change the mixer geometry once the bar has been
pulled in/let out to a certain point.
Another huge factor is the center of pressure (CoP) location and lift to drag ratio change based on everything I mentioned above, which then affects
bar pressure and collapse resistance. As you can see all of this starts getting quite complicated.
For lower bar pressure, moving the CoP forward is about the only thing you can do short of making a new canopy. The Jockov mixer should move the CoP
forward, but the decreased pulley ratio ratio may nullify the change. Adding some length the the Z and possibly even the C lines should help to reduce
the braking effect that pulls the CoP back. If the turning is too slow afterwards, you can try shortening 1 to 3 Z lines in the upper casacde at the
tip. That should speed up turning without too much added bar pressure.
