How many round-the-world airplanes or Spaceship Ones do you think he expects to sell? I suspect he wouldn't be interested in it, even if you brought a pile of money to pay for a design, because it's not as interesting as the stuff he's already working on. -- Change "netto" to "net" to email me directly Eric Greenwell Washington State USA |

Actually, Burt Rutan already designed and marketed a self launching
sailplane called the Solitaire, 20 years or so ago. http://www.rutanaircraft.com/htmlpages/orderform.html Photo, 2/3 down the page. I was quite excited about it at the time, but it did not turn out to be very successful -- too short span, too high wing loading, optimized for higher speeds, poor thermalling performance. It was quietly dropped from plans sales by RAF. -Bob Korves "Stewart Kissel" wrote in message ... http://www.scaled.com/projects/globalflyer.html Well if anyone out there in ras world is a buddy of Rutan...I suspect he might make some terrific sailplanes if he set his mind to it.

Any thoughts? |

You can't fly your friends in a PW6. They will be
to busy laughing at you. At 01:06 07 November 2004, Charles Yeates wrote: Good news -- but you could buy a PW-6U two-seater for 41,200 Euro and have the pleasure of flying friends, eh? Talking about the LS-4b: It's back in production (by Walter Eisele, a well-known german glider pilot), now called LS-4/2005. Price is 39.400 Euro, complete with retractable gear and water bags. Winglets are optional. Lots of bang for the buck if you ask me. Bye Andreas |

The SZD55 is almost identical in performance to a Discus
1. Build quality on the originals was not as good as the LS4 but perhaps the new builds are higher quality. The handling was not as good as the LS4 (but nothing touches an LS4 for handling) and the fuse looks like it's been beaten with the Jantar ugly stick. All in all, very good bang for buck. The only real problem is that it isn't competitive in any competition class right now. It's too hot for the club class and can't quite foot it with LS8s and D2s. I guess that will change over time.

Lots of bang for a buck, isn't it? ![]() Depends on the answer to the above question. I know for sure the LS4 is an excellent glider. I know nothing about the polish one. -- Michel TALON |

Well, considering the Solitaire motorglider, his last contribution to the world of soaring, I'd have to entertain some doubts. Not that I don't think he could, as you say, make terrific sailplanes. Just that I don't think he'd be inclined to play the incremental game of quarter-percentages that modern sailplane development seems to have become.

... And if the US$ continues to sink, maybe some of these will find their way to Europe. We'll have to sell boatloads to make up for our trade imbalance, though. Nope, since they don't meet the criteria for being certified and there is no category like "expereimental' in tha US, and anyway the cost and length of the certification process would probably discourage the manufacturer to attempt it. |

Bob K. http://www.hpaircraft.com/hp-24 *now under glass* It seems the aerodynamics of gliders has reached a point of near perfection where further performance increases are likely to be very small. Where I wish the designers would concentrate now is in the area of processes and materials where reductions in manufacturing costs might be realized. A breakthrough here would have large impact on the sport. Bill Daniels |

For some reason I suspect the very limited market would not be of much interest to him ![]() Actually, Rutan's track record for sailplanes is pretty bad - his Solitaire self-launch glider won the SSA/SHA (?) contest, but turned out to be a lousy sailplane due to it's canard configuration - couldn't thermal slow enough (a simplification of the problem with using canards at high Cls). Butt-ugly, too; makes a PW-5 look beautiful in comparison! I must be the only guy who thinks Rutan's designs are ugly and over-optimized. But they do work exceptionally well at their design missions, and one cannot argue with success! Kirk |
