The DeltaHawk of today (post ownership change) is worlds different from the previous incarnation that spent two decades trying to develop an engine. This engine will be certified, and it looks like it will be hard to justify a 100LL engine purchase in airframes where it is available when the time comes for overhaul. Great to see a company like this in GA committed to getting it across the finish line. Looking forward to seeing it at OSH in final form, numbers should be impressive.
