Meanwhile, I have a serious question about props. How difficult
is it to put a CS prop on a Wankle? I'm a bit puzzled about where
one would put the prop-governor -- oil or electric.

I've only just gotten some intro A&P books to read (because of
the orals for a Commercial Pilot's License).

And I too am thinking twin engine.

It is real hard or expensive to put a CS on a Wankel.
Bottom line is you don't need it. Set your pitch for cruise and
due to the exceptional power to weight ratio it will take off fine.

What about an electric adjustable? I believe it's ben haas  that has the ford stroker engine in a maule an is using a cog tooth belt psru and has an electric in flight adjustable on his that looks fairly simple. He has a video on YouTube that shows his set up.

Yes they will work. They are $10,000 and up. More than the engine and gear box.

Lol ok that shot that in the butt, didnt realize they were that expensive.
I have been curious though not so much for the adjustable
but more towards beta props for seaplane/amphibian  use .

That you need.

Some of the guys on here built one years ago.
I did some of the design.

The BETA system on a PT6 is interactive with fuel, control/rpm, all you need is a reversing prop, like the SeeBee
came with standard, for water use.
