I wonder what engine/prop RPMs are at 100%, what they will be at 75% cruise.
I wonder what the long term implications will be of using an engine that normally operates generating 25-40 hp (highway driving) and using it at at 50-75% power on a continuous basis. Car engines, even though they can produce high HP, normally do not operate in that HP range for long periods of time. I would'nt think they are designed to be efficient for that range.
