Lighten up, will ya. Nobody's interested in your bags of rags and strings, that's fodder for a different thread. I got a gold badge and distance diamond, so I've been more than two fences over. On the upside, I like your sailplane. I have flown a Pilatus and enjoyed it. Flies like a 1-35 and I always did like Schweizer sailplanes. PW-5flyer |

The local library carries the USHGA mag...and I also
read Davis Straub's webzine....I find the distinction between the latest rigid wing, control surface HG's, and the 13 Meter sailplanes on the market, rapidly closing. I know that 'foot launching' seems to be the key difference, but with the number of HG's winch and aero-towed...it would seem 'foot landing' is actually more accurate. And it seems the PG crowd's sheer numbers are starting to marginalize the HG's aging group. In fact I dare say the HG crowd may have more in common with sailplane pilots now(gasp, grown). Just throwing this out for discussion...it seems to me the groups have more then enough in common to band together. But no doubt there must be some good reasons this has not happened, I suppose At 15:30 22 December 2004, Tony Verhulst wrote: Stewart Kissel wrote: Hey Ed...

Well well...lol...great topical conversation...
Thank you, I think I got the ball rolling on this one. What a funny path you've chosen to go down.. It's winter, I'm bored and you guys are so easy to provoke. I will say maybe you should just back up your comments with an offer of a duel.. Did you mean Dual? cause I don't instruct anymore. Maybe you're right...maybe the PW-5 really IS better.. Thanks for playing the game. I've enjoyed it immensely. I'll be out of the office and out of town for the holidays, please continue to flame me as much as you all would like. Maybe we can do this again after the new year. Hope you all have a safe and happy holidays. PW-5 flyer |

AFAIK, SSA rejected the HG community in the 1970's. Someone doubtless has
the specific story. Frank Whiteley "Stewart Kissel" wrote in message ...

Hang glider? I don't need no stinking hang glider. Real pilots go cross country in this: http://www.skydiveelsinore.com/around-the-dz/birdman/ (-; Sorry, but the idea of cross country is to GO SOMEWHERE. I like to go somewhere far, to enjoy the scenery and the challenge, and then be sure to get back home for the barbecue and favorite beverage. -Bob |

One of the older threads mentioned that the Pegasus has pretty severe
wing flex. I wonder how important this is. Does anyone think wing flex has been a big deal during landing (esp. landouts) and catching a wingtip? Has anyone changed aircraft and used this (flex) as a metric that pushed them one way or another? It's very interesting to me how this issue is dealt with. Clearly designers are favoring mid or high-mid wings to high wing gliders (for performance reasons) and I've seen minimal dihedral in gliders (although in flight there is some, esp. the ETA, right?). I thought it was so incredibly funny that the ETA sketches (before it ever flew) showed very little curve, but in flight the flex was astonishing. Shorter span gliders (Sparrowhawk, PW-5, 1-26, AC-4) clearly have much less flex. I wonder to what extent the "landout willingness" is a factor of span, and how much is really a factor of flex. We talked about how flex may actually be helpful for getting extra energy out of turbulence "flapping wings like a seagull" but not so much about the downside (tips hitting on landing, ground clearance, etc.). The spaniest thing I've ever flown was the DG-1000, but it has what seem to be fairly stiff wings, and the tip extensions have pretty significant "dihedral." I don't know if this is the correct term for it since it is just for the tips, and not related to the fuselage, but it sure does give a bit more clearance. In this glider, span is certainly a consideration for runway lights, etc, but flex didn't seem to even come into play at all. I don't think I've ever even SEEN a 22 or 25 meter glider. How much flex do they have on the ground? Do the tips "almost touch" on every 1.2G landing? Are there any standards for landing tests? This is certainly something we don't encounter in airplan...err towplanes -- ------------+ Mark J. Boyd |

I saw a G103 slap both wing tips on the ground at the same time. (It was
just a normal landing for that particular pilot.) It didn't ground loop though. I guess the landout issue is still how high the grass or crop is. If the landing is gentle, the wings will keep some dihedral until the glider slows down. I think the term is "Polyhedral". There's a guy I know who flies a Jantar 2A and, despite the long droopy wings, he seems to handle it very well in the rough. He really likes the glider and is not particularly worried about a landout. Bill Daniels "Mark James Boyd" wrote in message news:41ca34cc$1@darkstar...
