Jim makes a good point. And a neat trick which is probably only in the
minds of us old farts is to weld a motorcycle spring to the bottom of
the mast, and the other end to a short piece of mast out of the rotor.
Had a buddy do that hundreds of years ago with a big 3 element 40,
when you could probably count the number of 40 meter beams in the
world and come up with less than 50.

Provides anti-torque on stat and stop.
