I was wondering what kind of cruise performance people are seeing on 100HP I would like to build the kitfox s7, because the published performance data looks really good to me, but I don't know how far this is off of reality.

I'm looking for climb performance, cruising speeds and on what hp you're getting those numbers. I've read a couple of threads on it, but the data has been based on the KF IV with an 80 hp rotax.
