I am into vtol craft and thats why i am into the most efficient not
so huge propellers, i pilot rc models and am currently testing
several designs

the propellers is the most important part of a vtol


engine ofcourse has to be light but todays engines are superb in that
aspect

I put this to you.

If you look at the latest VTOL series of rotorcraft, since the basic
helicopter design, you will find the answers you seek.

Hint: they don't have screw shaped rotors, for their lift producing
devices.

The Osprey has main rotors about halfway between helicopters of that weight
and prop planes of that weight. Very roughly.

Don't you think they would use the most efficient, smallest, lightest form
of prop that could be invented to do the job?

Hint: The answer is yes.
