Is this a joke ?
Jim Rooney - 2011/08/26 08:24:31 UTC
Thought I already answered that one... instead of quoting myself (have a look back if you don't believe me), I'll just reiterate it.
I don't advocate anything.
I use what we use at the flight parks. It's time tested and proven... and works a hell of a lot better than all the other bullshit I've seen out there.
130lb greenspot (greenspun?) cortland fishing line.
In stock at Quest, Highland, Eastern Shore, Kitty Hawk Kites, Florida Ridge, and I'm pretty sure Wallaby, Lookout and Morningside.
Morningside?

Davis has been at an around all this plenty long enough to understand what's what and who's who.
I'll put money that he's using that new orange stuff like what they've got up at Morningside.
I wouldn't be too sure about what they're using at Morningside.
How 'bout Australia?
Jim Rooney - 2013/02/15 06:48:18 UTC
I have no clue what they're using over there.
Well, it's almost certainly the same. If they'd...

AT isn't new. This stuff's been worked on and worked over for years and thousands upon thousands of tows.
...worked on and worked over this stuff for years and thousands upon thousands of tows they'd have inevitably reached exactly the same conclusion, right? I mean, don't all of their cars and bicycles use round wheels? And if they had decided on 120 or 140 pound Greenspot surely we'd be reading almost daily on the Oz Report about all the resulting carnage.
Not sure what Tracy up at Cloud Nine uses, but I'll put bets on the same.
I think you're pretty safe there.
Dr. Trisa Tilletti - 2012/06
There are many reasons, but for most pilots it is not because the standard 130 lb. green spot Dacron line used to make weak links for hang gliders is too weak.
Did you read their article in the 2012/06 issue of the magazine? I'd REALLY appreciate hearing your take on some of the issues.
Did I miss any?
Is it clear what I mean by "We"?
I dunno...

Weaklink testing
Davis Straub - 2013/07/04 13:47:57 UTC
Mark Knight and Jim Rooney put the loops through the wringer
Mark Knight
My calculations and test suggest the 200 lb. is right for me. I weigh 185 pounds, fly a T2 154 (75 lbs), and my harness fully loaded is 35 pounds. Total all up flying weight is 185 + 75+ 35 = 295 lbs. Times 1.4 = 413. I use Pro tow barrel release so divide by 2 = 206.5. I feel the White and purple is a good fit for me.
Mark Knight seems to think that the two hundred is right for him because it puts him close to 1.4 Gs - which is not a good rule of thumb.
I didn't make the system up.
No, you need to be someone other than Jim Rooney to...

Poll on weaklinks
Jim Rooney - 2013/03/04 19:31:36 UTC
Morningside decided that they were happy with 200lb weaklink. They changed their tug's link and they don't just pass the stuff out either. If you'd like to know more about it... go ask them.
...decide you're happy with something.
And I'm not so arrogant to think that my precious little ideas are going to magically revolutionise the industry.
So what are some of your precious little ideas? I thought that everything was...

I get tired as hell "refuting" all these mouth release and "strong link" arguments. Dig through the forums if you want that. I've been doing it for years but unfortunately the peddlers are religious in their beliefs so they find justification any way they can to "prove" their stuff. This is known as "Confirmation Bias"... seeking data to support your theory... it's back-asswards. Guess what? The shit doesn't work. If it did, we'd be using it everywhere. But it doesn't stand the test of reality.
...we'd be using it already.
If you have precious little ideas then surely you think that there are things being done wrong and can be done better. Hell, one of your professional pilot tandem aerotow buddies just got smeared all over the runway at Quest. Was that just the inevitable cost of doing business? If you have some precious little ideas what could be the harm in putting one or two of them forth in response?
There are far smarter people than me working this out.
I know, I've worked with them.

Quest Air Hang Gliding
Personable and fun, Dr. Mitch Shipley excels at flying - and at whatever else he decides to do, too. He's been hang gliding since 1987 and competed actively from 1995-2002. He flew more than 100 hours and 1000-2000 cross country miles each of those years, racking up numerous accolades and site records. He began flying tandem in 1997 so he could take his sons with him into the sky. He's introduced many others to the joys of hang gliding since, and is a gifted, empathetic and thorough instructor.
This overachiever graduated from the United States Naval Academy and completed a 21 year naval career in submarines and submarine related research.
Dr. Shipley? He says:

What can be learned from this "scooter" towing accident?
Mitch Shipley - 2011/01/31 15:22:59 UTC
Enjoy your posts, as always, and find your comments solid, based on hundreds of hours / tows of experience and backed up by a keen intellect/knowledge of the issues when it comes to most things in general and hang gliding AT/Towing in particular. Wanted to go on record in case anyone reading wanted to know one persons comments they should give weight to.
...you're at the top of this game - and I think if you survey the people still permitted to post on the Jack and Davis Shows you'll find the vast majority in total agreement.
(Bobby's a fucking genius when it comes to this shit... for example.)
So then, obviously, you vetted all your precious little ideas with Bobby and he refuted them.
So, that being the case, why do you still harbor precious little ideas? Were his explanations so far over your head that you couldn't understand them but you just assumed he must be right and you must be wrong because he's a fucking genius when it comes to this shit?
But, again, if you didn't have some doubts about his superhuman infallibility you wouldn't be continuing to harbor any of your precious little ideas, right?
So why aren't you posting any of them on The Davis Show. Are you absolutely positive that no one reading The Davis Show is a fucking genius in the ballpark of Bobby's caliber? Hell, Davis himself...

I'm very happy with the way Quest Air (Bobby Bailey designed) does it now.

As he took off his left wing was dragging. Bobby Bailey, the best tow pilot in the business, moved to the right into get further into the wind, and Rob got his left wing up and flying as he lined up behind Bobby.

Robin's accident
Davis Straub - 2005/06/14
If Bobby had released Robin at any time before the last two or three seconds he would likely not have crashed, at least not from a lockout.
The best in the business.
So c'mon, Jim. How 'bout throwing just one of your precious little ideas out for us muppets to contemplate. It would be such a refreshing change from hearing you constantly regurgitating all the moronic shit...

What happened to the org?

On the other hand there are plenty of people who fly lots but still manage to spew out the most incredible and dangerous garbage to others.
This includes some of the "professional" people who work in the industry and are therefore able to regard themselves as such.
They really believe they have a monopoly on knowledge and when finding themselves on the losing side of a debate resort to the old standby "This is what we do so fuck off you weekender".
I say good riddance to those nauseating, know it all, self indulgent "professionals" who have banished themselves from this site.
...spoon fed to you over the years by all your asshole mentors from Ridgely, Manquin, and Quest.
