M.Rad: I would guess people like Guy Fay has seen engineering reports that show test results of where the best RPM is for any given load. Lacking that info, I'll add my 2 cents from what I've seen on low RPM aircraft engines. Most operate at 75 percent for an average load. Their best miles per gallon would likely be 50 to 60 percent max RPM with average load but your adding time to completion. A very heavy load would require at least 75 percent. With all that said, I'll refer back in my memory to the days when I sat on an MD or gas M all day and say that if it handles the load fairly well, without relying on the governor, at 75 percent RPM, your probably close to best efficiency. agpilot
