Anyone currently flying a Ramoser Varioprop...
I have questions.
I'm trying to figure out about how much one of Christian's props unloads in flight..Whats the rpm swing from ground WOT to in flight.
Its my understanding, from Christian, that when mounted to a gas engine, the prop cannot exceed 6400 rpm unloaded (in flight) so trying to get an idea of where to start the tuning, rpm wise.
One person has told me 4800 but that seems very low. Thats a 1600 rpm difference between loaded and unloaded and I really don't think it will unload that much. I may be wrong.
I was thinking somewhere around 5200 to 5400 WOT loaded to start..am I off?
Hub I bought is the 25F hub with the 599-2f blades. 4 blade configuration.
