Hello Graeme,
Having looked at their website, I can't avoid the impression that it "looks"
heavy.
I've read their explanation of comparisons with other engines, yet the fact
that there are no cylinder cooling fins makes me wonder.
The engine which interests me quite a lot is the 6 cylinder D-Motor, although
there
doesn't seem to be enough information or history, at least not that I can
find. But the combination of side-valve and modern technology seems a great
concept
for aircraft applications.
I'll also watch Aeromomentum with interest.
