Just a question... I haven't checked out the price for Rotax engines but how does Lycoming make money? The way I see it, O-320 is 2ce as heavy as a Rotax 914 although it does have the extra 35hp which is not a lot considering the weight gain I think. Then there's the price. I'm assuming Rotax are a lot cheaper than the Lycoming (20k for a 280 or something along those lines?) I'm comparing certified vs certified here. But really, I just don't understand why anyone would buy a Lycoming over a Rotax given the specs on paper. Please comment and enlighten my ignorance in this regard.
