Autorotation

What is the angle of the blade at the tip of a UH-1 in Autorotation. Is this
angle somewhat the same for most Helicopters?

Which angle are you asking for?

Do you want to know what the blades actual AoA (angle of attack) is or do
you want to know what the blades angle of incidence is?

Angle of incidence?

My guess would be he wants the angle as measured on the ground like we'd do
on an RC heli. So incidence, not AoA.

I'm willing to bet he's an RC flyer too coz they're the only ones who want
to know that info :-))

As it happens, I'd be interested in knowing what the incidence angle is with
the lever fully lowered and the heli sat on the floor. I know it's nothing
like as negative as we can usefully make use of on RC machines, but there's
probably an optimum static setting for each type of heli.
