Peter,
Well, it's winter, I'll bite. Speaking of the Worlds, Clem Bowman was getting ready to take one to the Worlds - unfortunately that never happened. I'll defer to the opinions of Karl Striedieck, Bill Bartell, JJ Sinclair, David Mercer, Bob Salvo and Ron Gaynier. I believe all have won contest days with the ship. Dick Johnson's flight test (online at ssa.org, I believe) has a nice polar and a performance evaluation if you are interested. He even has overlay comparisons with a Discus to make it easy. Ever flown one? Mike Brooks |

Contest results are not always a good indication of glider performance though. A tiny perceived difference in performance will have all the top pilots flying one or two types and they will win. If you put that group of pilots in a different glider type they would still win. I flew the prototype Genesis at Uvalde, liked it, but didn't buy one. Andy |

Agreed that if you put top pilots in a different machine, they'll still win. We're talking a few percent one way or the other here. In my case at least, the ship is not the limiting factor. It's something to talk about until the season starts up, though.... Mike |

Sure, but the real question is (was) - if the Genesis 2 is as good as a Discus 2, why aren't there more G2's? Tony V. |

Sure, but the real question is (was) - if the Genesis 2 is as good as a Discus 2, why aren't there more G2's? Tony V. Good question. I think there are a lot of variables involved here. For one, the G2 is an unorthodox design, and I think we've seen that in many different aircraft that tends to lead to low production numbers. Beech Starship comes to mind. Clem Bowman's accident certainly must have had some effect on orders. We will never know what would have happened had he continued his successful racing career in the G2. Otherwise - there are plenty of designs that were successful sailplanes but had limited production runs. How about the Sisu? The number of units produced is not necessarily a good metric of the absolute value of a glider. The G2 can be debated in a number of ways. Some people just don't like they way they look - fair enough. That's personal taste. But if you have a look at the numbers (and maybe even fly one), I think the reason for the low production number lies outside the performance realm and gets into the area of manufacturing issues. My hat is off to the people that worked hard to produce them. Mike Brooks |
