Hi Henning,
Glad to hear you were able to resolve the initial difficulties you encountered running the MVVS. I have a Skystar 90 kit (unbuilt) that I was thinking about powering with a Hanno Special. The Skystar can be built so light, I figured the Hanno would have enough power. I also have a Webra Bully 1.20LS (rear exhaust) I could use, but it seems like overkill, plus it is considerably heavier than the Hanno. Probably about the same weight as the YS 1.10.
Happy Flying,
Will B.
