I have a 7a and normally run 2400RPM in cruise to avoid the "below 2350 RPM at 22+MP" prop limitation.
I have never done any experiements but wondered if 2400 was the most efficient place to run the prop.
Up high you won't get 22"MP anyway so in theory I can run the prop slower.
Anybody with any performance data to support running the prop slower?
Thanks
