So they are claiming around 30mph speed advantage over a lycoming engine on the RV10
Wonder what they could acheive in a really efficient airframe, such as the planned Panthera from Pipistrel

Much lighter than the IO390 as well.
I guess it makes a lot of sense for longer missions where you plan to fly FL150 for long periods of time with the comfort of a turbine engine. Not ideal for a bimble just outside the circuit
