Just wondering what happened to the Quintus and Antares 23 in the open class competitions around the globe. At the WGC in Uvalde both the Quintus and Antares were highly anticipated, with a pilot flying the Quintus winning the contest. Now the JS-1 at 21 meters seems to be the glider if you are going to race open class and want to win. Is it money, convenience or performance? I rarely see even an EB-29 in the open class competitions. What is the best open class glider and why?


As far as I know Lange haven't been building the Antares 23/Quintus main wing panels for a while.

If you have are prepared put up with the cost, size, weight, self launching engine maintenance, and ground handling etc of an EB29 and can fly like Michael Sommer then that would be the one to go for as the Open Class rules allow for wing span changes during a contest and the so you can have a shorter (still long!)span extremely high wing loading for the strong weather or a very long span lower wing loading glider for the weaker days.

Or save a lot of money and hassle and get as near as dammit the same cross country performance and lovely handling with a JS1c 21m.
