I'd think so.. I just about bought a Dragonfly
project, but was
discouraged by the weight limit for an engine, and
who wants to
fly behind a VW motor?.. If memory serves me
correct, a c-85 was
to much weight. A single rotor would fit, but that
might mean a
bit of a wait until they get on the market..

I owned and flew a Dragonfly for many years.  The 13B
is too heavy and powerful for that design.  It was
designed around a 1600cc vw, but others have installed
c-85/O-200, Jabiru, Subaru, etc, up to about 135hp.
Mine was powered by the humble VW for 240 hrs or so,
then switched over to a turbocharged Subaru EA81.
Performance increased significantly, and no more 50 hr
valve jobs req'd.

There was one fellow out near Mojave somewhere that
had built a single-rotor powerplant for the DF.  I
visited his hangar back in the mid-90's.  I have no
idea if it ever flew with that engine.
