Now, if they would put something in it other than a Rotax.

I have heard several pilots and my A&P express disdain for Rotax
engines. Why is this? They certainly seem to be popular with the
homebuilt and LSA crew. I have no experience with the aviation
versions.

One reason: They don't like 100LL. They're approved (and certified) to operate
on it, but the lead forms an abrasive sludge that means the oil has to be
changed more frequently.

Not that big of a deal with a private owner, but an FBO won't like having to
take a rental off the line twice as often to change the oil. The solution is to
run unleaded car gas, but the FBOs would have to add the infrastructure to
manage it as well as 100LL. It's for this reason I suspect the production
version of Cessna's LSA will have a Continental or Lycoming.

I believe Diamond's original Katana was the first certified Rotax-powered
aircraft sold in the US. However, FBOs had enough problems that the
Continental-powered version replaced it.

Keep in mind, though, not all LSAs are using Rotaxes. The ones that come from
Europe do (where they have more a tradition of running on car gas), but the
Cub-clones made in the US don't.

This is a sweet sounding engine, out on the ramp.

Being designed to run on unleaded car gas is a disadvantage? Hilarious.

Yeah, it does: first, car gas has other nasties, and second, it's seldom
available at airports. What's more, the FAA gets really ****ed if you pull a
LSA up to a Conoco or Diamond Shamrock station.

They have absolutely NO sense of humor.

Because you can't kill them if they give you lip.

'Cause you don't own a tuxedo.

Besides, if I remember that movie, the airport was in the Caribbean (e.g., not
on US soil).

But I have a license to "kill -9".

It's certainly a disadvantage if unleaded car gas isn't available at the
airport.

We've got one airport locally that sells mogas. Last year a local LSA dealer
asked the local pilots to petition the supplier to change to PREMIMUM unleaded
instead of regular unleaded. Turns out the line of plane he was selling
required premium. The guy didn't care that it would run everyone ELSE'S costs
up; he was desperate for his customers to avoid leaded fuel.

If the airport can sell more gas by selling premium instead of regular
unleaded, then they'd probably go that route. More and more of the Rotax
powered LSAs need premium, as does anyone flying with a 91 octane STC.
Unleaded premium might be the default autofuel of the future.
