If you have the money and time I would definitely go with a prop pitch. I
have a medium and a small PP. I am not sure which has more torque since
the medium has a (approx) 7100:1 gearbox and the small a 9600:1 but the
medium is probably tougher. Neither has ever free turned during a
windstorm and I have fairly large antennas. Both K7NV and W2FU have
amazing customer service should you have any issues or concerns.

THANK YOU!
Finally someone understands. I never meant my original reply about the
PST-61D to devolve into this lengthy discussion, but I couldn't let it
drop without the story being set straight. My situation is indeed
peculiar ... possibly even unique ... but some physically erroneous
comments were popping up in some of the replies that needed to be
corrected.
And yes, my options at this point appear to be either a PST-71D or a prop
pitch from K7NV. I've ruled out the PST-110D for two reasons ... one is
simply the weight of the beast, and the other is the fact that Pro-Sis-Tel
apparently went to a Hall Effect position sensor for it. Here is WA7NB's
experience with the PST-110D:

He ended up going with a prop pitch (don't remember which size). I
emailed Array Solutions to get their side of the story on WA7NB's issues,
but they never responded.
73 and thanks again,
Dave AB7E
