It seems there is another hurdle in my quest to fit a DeltaHawk diesel
to a Cruiser.  Their first engines, which will be ready in 2-3 years,
have the crankshaft about 4-5 inches lower than a Lyc or Cont.. This is
because they are a V4 design rather than opposed.  My question is, will
having a lower thrust line have any adverse effects to the flight
characteristics. The cowling will have to be custom made of course,  and
the use of a 3 bladed smaller prop would prevent it from striking the ground.

The engine dimensions are 23" wide by 19.2" high, with the center of the
crankshaft being 11.8" down from the top.

DeltaHawk says they will develop an inverted version for Lancair type
tractor aircraft. But I may be a really old man by then.

The prop diameter on a Cruiser is already less than ideal. A smaller
diameter prop would make it even less efficient. The prop diameter on 
my C182 is 84 inches. 

IMHO the availability of a DeltaHawk is about near the same as Zoche diesel :-)
Why has it taken them three years to fly one?
