A new szd55 is about 35k... Maybe a Discus CS is also at this price range. /Janos Where can I buy it???? I don't think you can buy a new Discus CS for much less than 50k$ in Europe. Just before they went bust LS offered LS4b for 45k€ IIRC (54k$). http://www.szdusa.com/catalog.html states the SZD at 39k$ with delivery by June 1999! I doubt very much the price has gone down since. And those prices are without instruments. PW-5 price then was 20k$ incl. basic instruments. |

It strikes me as odd that the most vocal argument against the PW-5 seems to be the "unconventional" aesthetics. Compared to some of the Schweizer designs or old European mixed construction types, I can't see the problem. If you compare it with our usual sleek plastic machines, I agree the high tail boom and conventional tail seem strange, but there is a logical explanation: a T-tail needs to have a much stronger tail boom to absorb the torsion loads. To have a conventional tail with sufficient ground clearance for field landings in crops, it has to be high-mounted. This design feature thus helps to keep the price down. Handsome is as handsome does, or? Hmmm let me think.... Our club bounced forward and bought one of the first 50 or so PW5 because we thought the concept of the World Class was a good idea and we should support it and enable our pilots to compete in such competitions. Very soon even the beginners realised that the PW5 was the poorest winch launcher by far (average 1200feet instead of the 1500 with Ka8, Ka6 or ASK23). Around the same time the club in Innsbruck totalled two of theirs on whinch launch and so for some strange reason nobody was really interested in flying the thing any longer. In it's second season someone landed in wheat only about 35" tall and gone was the tail - that doesn't happen with a T-tail. The repair cost almost as much as the new glider mainly because the spare parts are where they make the money. The horiz. stabiliser alone cost about $4500! During the following season the sweet little thing flew another 50 hours, there where no comps held anywhere and so we sold it again. And it happily lives in Belgium now. Hope it stays there.

Make that not enough interest in soaring to spend myself into the hole where I live only to fly, and you might be slightly more correct.. Flying is only one of many interesting things that the world has to offer, and not very high on the "bang for the buck." Very time consuming, very very expensive, and in most places, only seasonal. Why not respond to posts about something that makes sense to you because apparantly soaring makes absolutly no sense to you....... IF flying gliders lived up to the promise, more or less that of one person going up and doing his own thing then coming down and having a good bull session with friends, it would be ok, but it does not. The person that knows his limits, both in money to spend and risk he is willing to take will put up with an unwarranted barrage of ****mouth from a few that seem to think God only gave brains to them. Unfortunately, what God gave them was a big mouth and an empty head. What difference does it make to you if someone is flying only local in a 1-26, 2-33 or PW? What difference does it make to you that maybe he's happy with the situation as it is, content with what he has. What does it take away from you if he's not interested in competition or badges, even could care less about a diamond, microscopic as they are? Just exactly what does it take away from you if someone follows his own interests and ignores yours? How does it hurt you if he is flying in a PW and liking it? What is it taking away from you if he does? The activity itself, flying gliders, might make sense, it's the pilots that don't. |

Grob 102 3S Yeah Todd you really gained a lot by going with used G102, about 1 more L/D and a paint job that is going to cost you another G102...Right on! |

The L-13 canopy latch is a better (though far from perfect) example of a
side-canopy latch. If properly maintained, it is almost idiot proof because it latches automatically, much like your car door or the hood of your car. Your basic cam-acting door latch was probably invented hundreds of years ago; why can't we have this "space-age" technology in our gliders? Vaughn The Cezznas have this technology for the side doors, and it is a cause of occasional failure. There seems to be a philosophical and legal issue: if it is a stone-cold simple "pilot must move it to open or close" then it is obviously the pilot's fault if it isn't closed. If it slightly more complex, self-latching and it fails, the manufacturer is sued. So manufacturers would have to make self-latching canopy latches that are simply IMPOSSIBLE to fail. This is actually very, very challenging... The other issue is what if they fail to open when someone wants to eject? Or what if one can convince 12 senior citizens that this might have happened? Springs get debris in them or fail, latches and cams repeatedly rubbed eventually wear, etc. From a manufacturers standpoint, self-latching canopies are a no-no. I don't think we'll ever see them in manufacture by any company that can ever be sued... -- ------------+ Mark Boyd Avenal, California, USA |

No gliders less than 15m were entered. They were too low performance/
Not afraid of the World class just think that the PW5 is the wrong glider for it In general, it seems like 15 meters is the shortest span which can give good performance given the fairly wide range of pilot weights and sizes and the need for cockpit comfort. As a lightweight, I'd personally prefer something with less span. Paying for more span and then needing to add lots of water seems silly to me. But the market is what the market is, and manufacturers need to make gliders to fit the bulkier, richer pilots too... The lightweight construction techniques of the Sparrowhawk are really the only things that might make shorter spans competitive. I'm interested in seeing the performance of a retractable Sparrowhawk. For the next World Class glider, I wonder if retract will be allowed. I'd still like to see specifications which keep the cost down, however, and something's gotta give... In any case, I think the PW-5 and the Russia were an excellent start towards the World Class goals, but yes, in the intervening years better technologies have come along and there has been some learning. I hope this will make the next World Class glider manufacturers come up with some interesting designs... -- ------------+ Mark Boyd Avenal, California, USA |

No contest which I would buy But how about the Junior vs. a retract Russia AC-4c or a Sparrowhawk? The PeeWee simply won't be the next World Class glider. But there are other 15m gliders which may. Do you think 15m is simply the minimum span (a 12-13.5 meter glider is just silly?) And you glider makers and repairers out there (Bob K. and JJ), is there enough savings in weight and money to make the extra wing of 15m that a 12-13.5 meter glider costs significantly less? I don't know the answer to these questions, but I find them interesting. For me personally, the answer is just plain yes, I'm happier with less span. But if I weighed 225 lbs, I'd say just the opposite, perhaps... -- ------------+ Mark Boyd Avenal, California, USA |

Or what if one can convince 12 senior citizens that this might have happened? You could just as easily convince those same 12 white-hairs that this simple 100-year-old technology could have prevented an accident if it were incorporated into the design of a crashed glider. Springs get debris in them or fail, latches and cams repeatedly rubbed eventually wear, etc. Sorry, don't agree. The latches we have now fail. Even the self-latching canopy lock (as in the L-13) must be checked before flight (and should be a checklist item) the difference is that its NORMAL CONDITION IS SAFE. If you forget to check it, 99.999% of the time it won't kill you. What can be bad about that? From a manufacturers standpoint, self-latching canopies are a no-no. I don't think we'll ever see them in manufacture by any company that can ever be sued... By your logic, how did we ever get manufacturers to design self-connecting control hookups? (which also should be a checklist item before flight) Vaughn -- ------------+ Mark Boyd Avenal, California, USA |
