I spent a day and a half at Sebring looking at aircraft. As I expected,
there are only a few that fit what I'm looking for. Of those, only one (the
AMD Zodiac XLi) uses a Continental engine. Everyone else (and, indeed,
nearly everyone else building an LSA period) uses Rotax 912s.

I'm not fond of the idea of flying behind a Rotax. I know there are lots of
them out there (although I doubt what one guy told me, that there have been
more flight hours on Rotax engines than there have been on Lycomings and
Continentals put together), and I know that lots of folks like them, but I'm
not at all sure they're for me.

I live in Fairmont, Minnesota, a town of 11000 50 miles from anything. I'd
like the local A&P to be able to do maintenance on the engine, and fix it if
it breaks. I also need to feed it a steady diet of 100LL, as every gallon of
automobile gas sold in Minnesota must have at least 10% ethanol (and that's
supposed to go up to 20% in 2010).

I'm told the Rotax runs fast (red line on the Tecnam Sierra I sat in was
5500 RPM, and supposedly everyone recommends idling no lower than 2500), and
that it has very tight tolerances, and demands lots of special tools. Yeah,
it's just different, not necessarily worse - but there's a difference
between that and an O-200, where if I find myself at some random field with
a mechanic, I can be confident he can at least get it running.

The Zodiac's seating looks weird, although I'm reserving judgment until I
get to actually sit in one (the one they had at the show was being delivered
to a customer there today, so they didn't let anyone sit in it, and I didn't
get to go take a demo flight in the one they had there for that purpose).
I'd still like other options, but unless I'm convinced that the Rotax isn't
going to find itself at some point sitting in the hangar while the engine is
shipped off to another state for repair (or, worse, waiting on a replacement
cylinder that never comes because they're all being put on new engines),
there aren't any.

A flight school where I work has gotten rid of their Katanas because
Rotax only barely supports the engines anymore since they are
concentrating on the models used in homebuilts and LSAs. I guess that
it is only a problem if you have a Katana. Since Katana engines are
certificated to a different standard than the LSA and there has been
such an explosion in LSAs it makes sense for Rotax. I remember that
they had a couple of engines that always ran hot, troubleshooting
included removing them from one airplane and installing them in
another. Rotax couldn't figure out the problem either.
