That is an in-flight adjustable prop, not constant speed but still
adjustable. I think the writer is saying the weight
compares favorably with a IO-360 with all accessories and a constant speed
prop. The only real operational issue is the
requirement to watch the prop pitch control vs. manifold pressure and
twiddle as necessary to set the power; not quite
as easy as a constant speed but configurable never-the-less...


Right. I think other people's hesitations about the poster saying the V-8
is lighter, is possibly justified. Nevertheless, the possible heavier
weight should be more than offset by the higher HP, and I commend someone
giving alternate power a real, (from how it appears) well thought out
application, a chance to work.

As far as claims of fantastic economy goes, I think that anyone claiming to
be getting *substantially* better than .38 lbs/hp/hr, even with a modern
liquid cooled engine, are suspect.


Good luck to the OP. I wish I were involved in the project. Test test
test, before flying!
