I also really like the 912Is. Been to Oshkosh and also to the Idaho/Montana back country from Colorado. No issues at all even when flying with 2 people and a full load in back & full tanks. Also, the fuel economy is awesome. I was flying with my brother who has the 912ULS in his Kitfox. I was burning close to half what he was burning in cruise. I fly out of a field at 6800' in Colorado and I get off the ground faster than most. I have the Airmaster prop and am a big fan.
