Wow! That is cheap. We were looking at one a little closer to home, in the SE, about double that price. What's the catch? - they seem to be much cheaper than an equivalent Cessna, and 220HP is a hell of a lot more grunt up front.
I've never heard of a Franklin engine. Engineer I spoke to has never seen one
, but worked on Rallye's years ago, and said they all tended to have serious corrosion problems.
