Anyone tried comparing the old props, 3rd party old props and new QR props? I realized that the new props make a low humming bubbly sound. The old blades are much higher pitch. And the 3rd party carbon blades are even higher pitch. Upon comparing all 3, I realized the new props flex more at the wing tips. Banking hard left and right nonstop, it creates a chopping low pitch sound, almost like a v8. The old props sounds like a Honda VTEC, and the carbon props 3rd party sounds like turbine, quite high pitch. Anyone have similar experience? The new e800 flex quite a bit near the wing tips.
