Why not use feathers as propellor plates, helicopter blades. If you
could translate the rotational motion into flapping.

||Well, mainly because it's very difficult to find a feather that will support a load of several hundred (or in the case of a large helicopter, up to several thousand) kg.
||Does that answer your question?
||I said: does that answer your... yes, banana. Very good.
||If you had several gross of feathers this would probably work.
Of course, teaching the birds to flap while rotating would be
a challenge, as would keeping sufficient washer fluid to keep
the windshield clean.
||First of all, flapping on an aircraft would require just too
strong structure, so you would run inoto problems. Second-
propellers run at very high speeds (their tips are actually
supersonic at at least several moments) so feathers wouldnt
hold it. Also, helicopter blade parts near tips run at high
speeds so feathers also may not hold (birds fly up to
300kmh, but not 1200). But if you make helicopter blades
run quite slow and invent a mount to hold feathers, you CAN
make a helicopter blade using feathers, although it would
be rotating and not flapping as you desired.
