Default Which sustainer system would you chose for your sailplane?

I did ask, but there is no one in the US doing the retro fit - I was hoping to look at FES more at the convention. I would even consider buying a ASW20 or ASW27 in Europe and shipping it back - but I do not know the process.

If it were available as a retro fit I bet there would be a long line. For people like myself that want to do XC and want to do some contests, I believe FES is a game changer. (I know the romance about landing out.....) The increased drag/weight may keep me off a podium, but that is not my total interest as my skill level.

Unfortunately, it is highly unlikely that you will ever see FES units installed as a retrofit on various glider models. There are many reasons for this including: regulatory issues, legal issues, cost, design issues, market potential, installation complexity, etc, etc, etc. I am sure Luka could explain these various issues in more detail should he wish, but due to these reasons and others, the focus of LZ Design has been to offer the FES as an option on new gliders. Now, it all first began with the LAK-17A, that Luka Znidarsic used as the initial test bed and proof of concept glider. He then actually retrofitted a few LAK-17As that were shipped to his facility for the installations.

It was then offered as an option on the new LAK-17B and the Silent 2. As many of you know, in the past year, the FES is now offered by Schempp-Hirth on the Ventus 2cxa and the Discus 2c. It will also be offered on the new Ventus. HPH is also offering the FES on the Shark 304eS.

Finally, I hate to be a pessimist on this "retrofit" idea for other models, but I am doubtful that this will ever become a reality (except for perhaps some additional LAK-17As). Now, that being said, we all know things can change (just like the weather) and one should "never say never," but this is basically where we are today.... Thx - Renny
