Large displace for its diameter. It was originally designed as a

torpedo

engine. It's Achilles heel is the line contact between the
piston roller and the wobble plate.

Right Norm! Sorry. Brain fade. Yes I remember now. The RAND Cam.
Getting old :)

Here is what I have to say about that. Not to mention
50 years and untold billions invested in the wankel so far.

As Paul pointed out, all of the cam related engines suffer from the
high local stresses on the cam surfaces. Many of these are inspired
by the thought that added combustion time at TDC is a major
benifit (the infamous Bourke engine being a prime example with
an almost religous following). Any changes from this are miniscule
and the resulting engines are almost always heavier and more
expensive than conventional designs. Vance J

on the net. I don't they reference the same engine but I don't know.
