Dear Paul.

Generally speaking,  is the weight of a firewall forward "wet", ready to fly, Wankel installation the same as one for Lycomings and Conti's ?

What can you say about the AE50R of Austro and the XR50 of Poul Wolffe.  One costs twice the other.

Who are the makers of Wankels in the 50 - 100 hp range ?

Thanks and best regards.
Benjamin.

Yes it is in the 180 to 200 HP range. That would be a side port
Mazda 2 rotor engine. A p-port 2 rotor engine is 250 HP so that has about
a 100 pound weight advantage over a 6 cylinder air craft engine
like a Continental 230 HP  O-470 or a O-540 Lycoming.

The Austro engine has been used in 500 motor gliders so
there is a lot more experience in aircraft with that engine.
The 40 to 50 HP AIXRO is relatively new to aircraft.

AIXRO and Austro are the only companies shipping engines
in the 50 HP range. The closest you will come right at
the moment around 100 HP is a one rotor Mazda.
