The blades can't grab air in a complete vacuum or very high altitudes.
When this happens everything becomes a rock.
With counter-rotating props the front blades act as sort of a turbo for the rear blades.
Instead of being enveloped in nothingness, they now work in a pre-pressurized envelope.
So regardless of conditions:
-slow and low -vs.- high and fast
-either the front set or the back set should be able to pull at full capacity...at the slight cost of inefficiency with the other set.
