ain't happenin' two or three times a weekend - ANYWHERE. And if it were there'd be a lot fewer gliders taking their wheels off before getting on the cart.
- So what power DO you use? What's your setting/climb compared to a 582? And wouldn't that intermediate power setting be very confusing to pilots trying to decide what technique - 582 or 914 - to use?
- Oh. You wouldn't be going faster horizontally but your accelleration and climb rate would be so extreme that most pilots couldn't keep up the timing needed to make it work. Which means that you're going STRAIGHT UP. And accellerating the whole time. Until you hit about eighty thousand feet and Mach 20. Then there's really not enough air for the prop to push off of. (Do try to avoid cool macho aviation terms you can't spell - 'specially the ones for which you have no fuckin' clues regarding the meanings.)
Yeah, that would be a real bitch to fly behind. I'm not supposed to have my nose up over thirty degrees.
Departing the launch cart
I guess that's the reason we never actually hear about people leaving the cart at the wrong time (early or late) - just a lot of semiliterate pretentious blatherings from Jim Keen-Intellect Rooney.Jim Rooney - 2007/09/01 02:39:53 UTC
Yes, it's technically possible in a theoretical sort of way.
Yes, there are other factor, which is why it isn't done...
First off I guess is that a simple conversation fixes the problem, or the problem is unfixable.
Let me explain.
See one side is lack of information, the idea that 914s require a different launch technique.
The other is a pilots willingness to adjust.
The first is easily solved with a simple conversation but only if the second is possible.
See, there's no 'learning curve'. You either wait stubbornly till you're lifting the cart, cuz "that's the 'right' way", or you don't. The timing is easy. You actually have to work hard to leave the cart at the wrong time (early or late).
Already? You couldn't elaborate on all these people having to work hard to leave the cart at the wrong time (early or late) or show us some relevant videos?Next up...

2007 Worlds - nobody died
And this is something Hiih Gland Aerosports AT pilots need to worry about? Launch lotsa people who don't understand that they're supposed to hold onto the cart before and while they're rolling? Sounds to me like you gotta totally work your ass off to fuck up one of these launches.Davis Straub - 2007/08/23 14:58:11 UTC
There was only two minor accidents that resulted in injury to pilots during the 2007 Worlds.
The one accident that happened on the line came when a pilot had taken off his wheels (he was the only pilot flying with wheels) and when he came off the cart slow and too early. His English wasn't good so he may not have understood the requests for him to hold on and he was one of the least experienced pilots at the Worlds.

Yes. YOU already do. Nobody else at Ridgely or any other operation you know about... Just YOU - YOU being your favorite topic.I already do.
- Likewise clearly implying that tons of other people DO.I don't tow solos under full power...
- So what power DO you use? What's your setting/climb compared to a 582? And wouldn't that intermediate power setting be very confusing to pilots trying to decide what technique - 582 or 914 - to use?
I'm thinking NOT. I'm thinking it's one of those dawn and dusk things. That maybe you need to be using a 748 technique - halfway between 582 and 914 - as a rule of thumb. I'm thinking that if different 914 pilots were using different throttle settings the glider pilots would need to adjusting their techniques and it would be very difficult to calculate when the hogwash would hit and how hard.Jim Rooney - 2007/08/25 02:24:44 UTC
582 / 914 = all the difference in the world.
It's a pointless discussion otherwise.
That's what I'm getting at here... it's a 582 technique that works with 582s, but it's counter productive behind 914s.
This is one of those night and day things.
Behind Chad, Sunny, Adam, Lisa, Zack, Windsor, Les, Keavy... No problem....you could't keep up with me if I did.
Fuck. I so do enjoy flying faster horizontally when I tow.I wouldn't be going faster horizontally...
- How much accellerating do you typically do after you've lifted off the runway at Mach 6.5? What are your airspeed indicator readings at fifty and two thousand feet? Can we see a video of a Dragonfly accellerating throughout a climb to two grand? I know a glider trying to follow it would be torn to shreds before it got up to two hundred so just make it a Dragonfly with nothing behind it....but my accelleration and climb rate would be so extreme that most pilots couldn't keep up the timing needed to make it work.

Yeah, he's an ace aerobatic pilot. (Did he have his parachute connected to his harness for that one?)(I think Bo's the only one I've successfully towed at full boost)
