Something like the Hygain AR40 might last undertaken those conditions and they are over $300

In the 9521 instructions it says "use no more than 3 feet of mast above the rotor"

I see, I had not thought that the inertia of the mass of the mast stopping.

Well, I am already in the market for a new type of rotator. I found the Yaesu, but I don't think there is a remote:

You are correct the AR-40 is comparatively expensive:
