My vote goes for the first technology that can be fitted to a Libelle!


And I only want a system which can provide enough power to self-launch an 18m or larger glider, and have sufficient power left for a relight and/or a long retrieve. Which today means a combustion engine.

But I have to say that if I did not want self-launch, either the FES or the Jet would seem overwhelmingly better than the Turbo. For me it would be the jet because I don't like the idea of even a little drag from the prop, and I feel uneasy about having a mechanism in front of my feet - but it would have to be a jet which gives a good rate of climb, which if I understood correctly pretty much means a JS1 or an HP304.
