If I take everything on the Viking website at face value then I have to conclude that it is far superior to Rotax in every single way. The problem is that the company's advertising is just about the only source of info and Eggenfellner himself has admitted to being a bit too "optimistic" at times. For this reason I would love to get unbiased first hand reports on things like installed weight and output. When I see that a Viking adopter is unwilling to reveal such info, I can't help but assume the worst. Sorry, but that's the way it is.
A couple of points in regard to this discussion.
First, I don't care how much the Viking installation weighs, I'm not building an RV-12.
Second, anyone is free to assume whatever they wish concerning whatever they wish.
Third, the reason I chimed in on this matter (in which I have no skin except as a moderator) is the way some posters seem to feel they can
demand that a builder submit whatever info they wish to see, and if that demand isn't met, they will respond with posts that would best be left unposted.
If I decide to withhold information about what my plane weighs, it is nobody's business regardless of whatever you say you are going to assume. The flying weight of the Viking engine will be known soon enough as installations are completed....there is no need to browbeat a particular builder into providing info he said he preferred not to state. I'm looking forward to hearing how Ron's Viking performs in the air.
