True, but aren't we talking about 40 cps when the prop RPM is 2400?

At cruise RPM that effect would be completely lost. There's not a
bird or human alive that can discern stroboscopic effects of more than
a couple hundred cycles let alone over a 1000. Most of us can't even
discern 60 cps.

Would be quite useful if it really worked. Of course there would still be
strikes with inattentive and near-sighted birds. ;-)
