MessageFinally got there.  After the first few 5 second aborted runs
correcting the inevitable half dozen 'oops' items (missing plug in
unused oil injection passage, etc, etc, etc.) the engine ran fine with
no surprises.   There is very little to be learned on a first engine
run, it is mainly a ceremonial occasion.  The prop is not on so didn't
get to hear what it sounds like under load but the exhaust note is
much more mellow at idle than PP exhaust, probably even better than my
first impression because this was inside the hangar which amplifies
exhaust noise (a lot).

The biggest difference was something that did not occur to me until I
was walking upstairs after the last engine run of the 'day' (it was
1:30 AM).  I had run the engine inside the hangar with the door closed
for several minutes without even noticing much exhaust smell.   I
couldn't run my earlier rotaries for more than 30 seconds before my
eyes would start watering.   The Renesis must be an order of magnitude
cleaner in the exhaust department.

Now if these darn hurricanes will un-ass the area, I will flight test
this thing.
