[Towertalk] Prop-Pitch

[Greg Gobleman]

I was looking at the photos of this prop pitch, not having seen one mounted
I was trying to figure out how they are installed.  I assume the flat plate
area is bolted to a stationary plate.  Is a notched piece made to adapt to
the mast pipe?  I also have read of needing to rig a directional indicator
of some kind.  Any info on that?  May I assume that the control box and
indicator will probably cost as much as the rotor?
