If
they would sacrifice a little bit of power, by going to a shorter prop,

one with more blades, or slow the RPM's a bit, I would indeed enjoy
them.


You want bigger blades; not shorter. The rasping noise the Red Barons
make is
the blade tips going supersonic. Shorter blades go even faster.

Personally, I find that rasp is like music.

Ummm...no, it's all a function of blade diameter and the corresponding
circumference of the prop at the tip. At the same RPM, the shorter blade's
tips are traveling SLOWER (due to the smaller circumference) than a larger
blade.
