im sick of this post too

you said > The issue that all the pressure fans miss is that there is more power efficiency, not more lift.(the power required reduces because the extra lift is extinguished by reducing collective.) This efficiency is brought about becuse the ground changes the direction of the flow, NOT its pressure.
why are'nt blades made to produce this changed direction of flow and have the extra efficiency all the time??

DeltaFree, spot on!
