They describe it as having "high torque," which begs the question
"compared

department , particularly at low rpm. While this isn't an issue for
aircraft
use, if they'd mislead us on this point, what else should we know about
them?

This engine is also charge-cooled. I'm wondering if they've solved the
shortcomings of this arrangement or not, and as mentioned, their prices.
Here's hoping...

Maybe someone can clear up a little confusion on my part.  I remember some
air-cooled German wankels manufactured by Fichtel & Sachs as industrial and
snowmobile engines.  As I understand it, the rights and tooling were sold to
Norton who developed motorcycle, drone and light aircraft versions.  The
light aircraft version was sold to Midlands something or other, which was
then sold back to a German company, who I believe sold it to Diamond
Engines.  Are these engines the same or license-built?  I seem to remember
that the Sachs engines had an integral cooling fan but were also fuel/oil
cooled.

Nothing to do with Sachs or Norton.
Norton had their own license from Wankel Gmbh or NSU/Audi. The rights were then 
divided to Midwest Engines for GA aircraft use later to become Diamond Engines. 
(Currently). Drone use to another company. Wankel Gmbh was resurrected in the 
nineties in Korf Germany with an entirely new design. Juergen Bax as 
the president. I visited the factory in Korf in 1999.
