Would you put a 6200 RPM stall converter on a street driven small block Chevy? Same thing as propping a Saito FA-180 @ 10,000 RPM static.
I agree
As far as how much ANY prop will unload in the air? That would depend on the airframe. It would unload a lot more on a P-51 @ 80 MPH than it would on a J-3 doing 40 MPH
I understood that
I think an 18x8 at 7900 RPM static would unload a lot more than a 15x8 because @ 7900 RPM it would already be in the fat part of the power band ready for more, not gasping for air at the top end.
good point.
What's the point in the 15x8 anyway?
edited> well, you know, about a given plane, with a given engine, and a given smaller prop of the "correct size and pitch" will or can or could produce more Top Speed than a larger prop with less pitch, so I was just wondering how much their differences would be in how much the 2 props would unload,, one would naturally think the smaller prop would unload more because it has less area, but I can see now how it may not
sorry for the edit, I just want to get my thoughts straight for you guys
