Yes, I had a modified prop pitch on an installation I did several years ago
and it would windmill with just the 60 ft boom of the 80 meter beam. After
changing to an unmodified gearbox it would still windmill some with the 3
element 80 and 4 element 40 meter beams, but was only a problem with strong
winds. Had ropes tied to the ends ot the boom of the 80 to tie it down when
the real heavy winds came.
