What killed the World Class was the World Class.
When the PW5 was awarded the World Class against a lot of opposition to the design the proponents of the PW5 sat back fielding criticism and smugly snubbed the others even after it was well apparent that few were going to get on their band wagon. Others that contended for the bid to be the world class glider and their followers were shut out and left with no place to compete. There were other good design entrants (most thought better than the committee picked PW5) and rumors of unfair politics deciding on the PW5 clouded the class. How the PW5 was picked over the other designs remains a topic of some controversy but it was and it failed to gather the interest of the masses (it really is homely) but there were however many other gliders that were in contention for the title sold that already meet much the original design criteria. If these models were all lumped together with the existing PW5 gliders the potential is there for a successful competition class to yet emerge.... Call it World Class or whatever you like but stick with the gliders already produced and there is no need to go through the process another time only to end up with the same dismal results. There is no need to start including Grob Astirs, Cirrus, LS4 and the likes of these since they already fit nicely into the Club Class (The USA needs also to finally adopt the rest of the worlds "Club Class" and "Racing Class" rather than continuing to disguise Ventus 2's and ASW27's and the likes as "Sports class" gliders)and there is no reason to start looking for a new alternative "World Class" design... Simply include the L-33's, SZD solo, Russia in with the PW5's and let them fight it out in a fair and balanced contest.....choose your weapon and go into battle..... low cost, lower performance racing.....easy enough. tim -- Please visit the Wings & Wheels website at www.wingsandwheels.com , "Ian Cant" wrote in message ... Soon we will see a very good 13m glider ....for $120,000.-only. And the happy owner will be a World Class Champion. Was that an original idea behind the World Class? If I recall correctly, the major aim of the World Class concept was to make competition soaring more accessible by keeping the cost down. The lower performance level and the single-design concepts arose from this aim [one design to allow mass production and the savings therefrom]. Unfortunately the masses did not buy the PW-5. Perhaps a reasonable class could be built from all the 13m and below sailplanes that are now around, typically with 30 or 35:1 L/Ds and easier retrieve characteristics than bigger ships. A set of rules can be built around the existing designs without denying entry to newer and better designs. Contrary to advertised beliefs, 30:1 is plenty for X-C [20:1 is plenty for the 1-26 guys]. But how do we keep the cost under control ? Well, my only semi-facetious suggestion would be to have a rule that the top three in any National-level contest have to offer their ships, fully equipped as flown, for sale at a fixed price immediately afterwards. Take $40,000 as a random number. Will anyone really want to buy a championship with a $60,000 ship if he has to sell it for $40,000 afterwards ? It would be snapped up. But the $20,000 ship that wins would probably not be sellable at $40,000 and the owner could keep it to fly another day. As a reference point, the Sparrowhawk is perhaps the highest performance 13m ship around, and I believe it still sells for below $40,000. And my aging Russia would be competitive; it cost me $19,000 new a few years ago; even with a trailer and flight recorder and oxygen etc and CA sales tax, it still came in at well below $25,000. It could be done. With 60 or so Russias, maybe 50 PW-5s, a growing number of Sparrowhawks and a sprinkling of Apis and Silents we should have a viable nucleus of a fleet. And if it works, more people may be enticed to join in affordable competive soaring. Ian |

Here, Here Tim:
The Club Class has definitely stepped up and filled the performance/ price niche the orginal World Class was meant to fill in the soaring contest world. Club Class around the world offers some of the most competitive racing in the world right now, in ships that more pilots can afford - especially inthe US given the Euro/$ rate now. Every country in the world offers Club Class racing except the US (and maybe Canada?). Why are we so stubbornly against the concept, while we still devote the time and effort to site a World Class Nationals every year? Yes, some rules makers have said to me : "well look at the Club Class in Europe, with all of its highly modified Cirruses, etc., that will just mean pilots will take $20K Cirruses and trick them out for $40K , and then where is the affordability?" I was once of that thought. But after having seen the 3rd French Pilot in a run-of-the mill Std Cirrus place 3rd at Club Worlds ahead of the supposedly tricked out Cirrus' the top two French pilots flew, I just do not think that is much of an issue. There is only so much you can do with Cirrus, Libelles, etc. And now that the IGC Club Class list is adding the Discus (and like ships) to the list of ships allowed, the Club class alows a huge portion of the US fleet of gliders to compete at a high level again. Isn't that a good thing? Oh, and even if it takes $40k to trick out and old ship to be fully competitive, I've still saved a good number 10's of thousands of $'s with which I can compete at more contests. Isn't the possibility of increased contest participation a good thing as well? Others have said to me: "why should I have to purchase an old Libelle to compete in a contest where I can make the US Team?" And good/great pilots (often younger) who can only afford crappy gliders or who's dads don't have a D2 for them to fly should have to buy $100k new ships to compete on an even palying field in the only handicapped class the US offers pilots? The concept of the US Sports Natioanls has outlived its usefullness - other than to offer pilots more options of flying a nationals each year. If I own a new ASW-15 meter ship, my nationals should be the 15 meter class. If I own a Schempp-Std Class glider my nationals should be Stds Nationals. If I own a whatever-Open Class ship, I might be clamoring for a handicapped Open Class to attract more ships to that nationals since Sports Class does not cater to me at all. etc. But if I own a Libelle, or Elfe, or whatever older ship, I am S.O.L. for my own Nationals. The current Sports Class Nationals has become a joke for entry level racing here in the US - unless you can afford to buy a brand new ship and start racing it as a newbie, OR you can find a glider that has not been raced in the last 20-30 years and has an overly generous handicap so you can try and "work" the current system. Otherwise, you need to depend on a lot of luck fromt he weather gods and superior pilot skills to have any hope of winning. Instead Sports Class has become just another "option" for pilots of the latest and best ships. Many pilots I am sure say: "Well, I own an ASW-50, my nationals is in XXX. I don't like XXX, but Sports Nationals is in a place I do like... I might as well just fly Sports Nats and maybe even pick up a high nationals placing since the tasking is, after all, more and more set up for ships like mine because that is (mostly) who goes to it anymore." Keep the Sports Class at the regional level - its fun to race agaisnt others outside of your class and to learn in, BUT give US pilots their own Club Class Nationals like everyone else in the world has! Let the World Class, as a separate nationals, die quietly and maybe set up an A and B Club Class Nationals system and give the US soaring population a Club Class Nationals to fill the entry level/affordable/ very competitive contest niche.

Really nobody "tricks out" their gliders. Everybody seals their glider properly but that doesn't cost much. If you add winglets (~ $2,000) or wing-root fillets (which probably don't work unless you've done wind tunnel time) you get extra handicap, so it doesn't make any difference, and so pilots don't bother. Certainly nobody is spending tens of thousands of dollars, not even close. Dan |

Cheap with performance...then lets pitch the one design(which
is really who can trick out their ship the most and gain L/d, thus defeating the concept) Run any ship within certain handicaps...a range that go from Russias and PW5 up to LS4? Keep the handicap. One can try to get the cheapest glider with the best handicap, or something a little more expensive that takes a bigger hit. Not including LS4's in this group would be a big mistake IMVHO, they are good performers and relatively cheap used...is that not the objective? |

In any case, the cost of these "tricks" is a lot less than the "tricks" the manufacturers can add to their new gliders, and then the competitors do the usual tricks in addition. New glider + usual tricks is a significant gain in performance and cost. -- Eric Greenwell - Washington State, USA * Change "netto" to "net" to email me directly * "Transponders in Sailplanes" http://tinyurl.com/y739x4 * "A Guide to Self-launching Sailplane Operation" at www.motorglider.org |

Specific features such as the nose wheel and non-retractable landing gear. It also leads to sacrificing performance for easier handling. I agree about the 'dumbing down' aspect, but performance can be built in as mentioned in the Discus/LS4 rebuttal, so it's performance disadvantage is to cut costs in addition to 'dumbing down'. Time to update your knowledge to at least the 1980s, when the LS4, Discus, and other gliders showed you don't have to sacrifice performance to have a glider with wonderful, forgiving handling. -- Eric Greenwell - Washington State, USA Then why doesn't the PW5 have better performance ? As mentioned, due to cost/dumbing down (read fixed gear). Trade offs between handling and performance might be: span, easier handling with lower span. wing loading, high for performance, low for safety, happy medium ? airfoil and twist for better performance or stall ? fixed gear vs retract. high wing for safety vs lower drag mid wing ? Actually a high wing is more efficient (I believe due to better lift distribution). Don't believe me though, find some technical reports by OSTIV and look at what will probably be the newest Shleicher ubership. It is called the MU: 31, and it is essentially a 27 (it's fuselage is considered to be just about optimal, drag wise, since it has to house a human and be crash safe it is hard to get much better) with the wing moved to the high position. The trailing edge actually terminates on a pylon to maintain it's optimal hight at optimal angle of incidence. It has -7 degrees of inboard washout (wash-in?) in the first meter which gives it a strange anhedral sort of look, and these nifty little dimples in front of the wing/fuselage juncture to discourage horseshoe vortecies. Due to these mods, it has 16% less induced drag, and induced being 1/3 of total drag has around a 5% lower sink rate than a normal 27, but the high wing is said by them to be more efficient, although admittedly it does not look as cool. If you can't find anything on the MU: 31 and want to see it, I can archive and link my scanned version of it I have on disk. It really is cool. All of these items can be optimized one way or the other. The LS4/ Discus got a really good happy medium with both good handling and performance. If the PW5 had near the performance of either of these gliders, I would own a PW5, but the PW5 does not. Todd The PW-5's performance is not too bad, but it sure ain't no looker. That is what I believe turns a lot of people off the idea, when they can get a much cooler looking ship for less money! I do think there ought to be a one design ship though, but I would much rather see the Sparrowhawk be it. Paul Hanson "Do the usual, unusually well"--Len Niemi |

you guys are funny!
For decent performance I think 35/1 would be good enough. Lower performance is just frustrating when trying XC. i have no experience flying cross country in anything 35:1 or higher, but it seems to me like it may be kind of boring, i mean you are way up in the air all the time, never get close to the ground until youve made the goal, wheres the excitement?? Makes the "club" less exclusive - I became a cross-county pilot and fly in contests because I fly a ship I can afford. Modest initial cost, inexpensive insurance, zero maintenance - amen and this is why i bought the Cherokee they did not seem to be having much fun, because they landed out all the damn time. now im afraid to move up to high performance soaring, if landing out isnt fun, of course as long as nothing gets broken, then what is fun? ive had nearly as much fun on some of my retrieves as some of my flights. oh i like the 'claim' idea. reminds me of when i used to go to the local dirt track races. other racers had the opportunity to claim parts of the top 5 cars at the end of the race. preset prices for standard items. kept costs down for everyone and helped even the playing field. i think we should just leave those poor PW-5's alone, i mean usually RAS doesnt start picking on them until at least later into the fall or winter. I personally like the idea of a one design class for contests. I wouldnt even care WHICH design it was but as long as it was affordable enough for an average pilot to get into. when the entire field is running the same glider in the same weather over the same course the only way you win is by being the best pilot and isnt that what we are trying to figure out anyway? |

I have limited XC experience in a nominally greater than 1:35 Std Cirrus, and
early XC in a 1:27 Blanik L13, and a couple of flights in a Kestrel 19. Of the three performance bands the Standard class Cirrus is the most fun for me - probably because it is mine, and I have the most experience in it. The lower performance is very frustrating because it is so slow getting anywhere. The performance of the Kestrel means that you have to fly far to be challenging - in high winds even the Cirrus can get tiresome trying to go upwind... Getting low is a consequence of weather and pilot choices. Where I fly there is usually lots of energy and anything less than 2000 feet AGL is "low" and wasting time because the thermals tend to get scrappy and disorganised. That said I have spent my fair share of time grinding away from some low position. Usually as a consequence of my poor decision making. Landouts happen to all of them, even the 1:60+ uber bugsmashers. They just tend to happen a lot further away from home. Which can make retrieves a real adventure, or unmitigated pain. Consider the crew a little while ago who I watched scurrying around for a second trailer that could handle an 18m racer when both of their pilots called below glide 150km away at 17:00... On rural dirt roads in the part of the world these guys were in that could be a very long process. Consider that the area these guys were getting low in is pretty uninhabited. As one French pilot found out in the 2001 worlds, there are places you can land in a tilled field and have , no radio comms, no cell phone and no building in sight from the circuit. How pleasant an outlanding is depends largely on crew and how easy it is to get your glider home. The one outlanding involving the L13 was a nightmare. The trailer is open, and the fittings badly designed, and now old and abused. Then he lands where the rocks prevent getting a trailer in close. Conversely, the Cirrus is easy to derig and has a good trailer, so it is no major problem most of the time. Never tried it , but there is an adage that you know who your real friends are the second time you ask them to retrieve you with a Kestrel 19. How much fun you have depends on your attitude - not on your equipment. wrote: you guys are funny! For decent performance I think 35/1 would be good enough.
