We had a question: 

Since the 180HP variant is going to be the first model certified, how about posting a DH180V4 economic comparison chart with the O-360?

After checking further into the Economic Comparison question, I discovered that the reason we did them for the 160hp and 200hp is because we had reliable performance data for Lycoming engines in 160hp and 200hp on airplanes that we owned. We did not have an airplane with a gas 180hp engine to gather performance data from. We still don't, so we will not provide the Economic Comparison for the 180hp engines until we have the 180hp gas engine data. It is safe to assume that the savings with the 180hp DeltaHawk models will be between the other two models.
