I like their concept, but there always seems to be a promising new engine that is "1-2 years away". Hopefully this one will make it, but the odds are against it. And a note of caution: Horsepower is horsepower and that's what it takes. More "torque" available? Horsepower is torque times rpm and hp is what gets the plane off the ground. I'm afraid with only 200 hp you will be disappointed, as the ES is a fairly heavy plane. I think all the original 210-hp ES's have been converted to 300 hp engines for that reason.

starting on our ES fastbuild, so 2 or 3 years away from engine =
decision. Love the concept of the Deltahawk 200 hp. They say =
they are 1-2 years away from cert. engines, experimental sooner. =
200 hp should be plenty for takeoff, since much more torque available, =
and the 200 is there all the way up to flight levels. Fuel savings =
in 2000 hours will pay for the engine, plus no worries about 100 =
LL. Anyone else looking at this engine? Ed =
