The Sgian Dubh prop was made more like
a paddle to increase the ground clearance on landing
and taking off. Peak revs on the ground was 6,200 rpm:

The Iolaire prop was for a BMW 100RS;
was quiet, worked well and I limited the rpm to 4000:

The single bladed prop was an experimental
one in 1984, was quiet but a thin but broader anti vortex
tip improved the range, this was also very quiet:
