Was looking through the new EAA magazine today and came across an add for "viking aircraft engines". It's based on the honda fit engine and looks to be about 30lbs more than a 912 ULS but with 110 hp, MPFI, 40amp alt, etc.

Obviously, its viability remains to be seen, but any first impression thoughts?
