superbly in that service. They are also as scarce as hens-teeth. And
I'm sure your 55-year-old prop pitch rotators will be giving fine service
to your grandchildren's heirs, but not all of us can afford, nor need
The new bell-housing rotators are also absurdly expensive, but it is a
lot easier to find used ones in servicable condition, or to bring back
one to condition yourself. (My Ham-M cost me less than $50 recently, plus
a couple hours of work to service it) If a few aerodynamic tricks make
the bell-housing rotators perform better, that's not a "band-aid", but a
good idea. Let's save those prop-pitches for when we really need them.
