[TowerTalk] MA550 movement w/wind

[Dick Green WC1M]

I have an MA-770MDP. Looks normal to me. I agree that it's a combination of
rotor slop and twisting of the tubes.

You might be able to reduce the movement of the tubes by cranking the mast
down a few inches after you raise it. This will put a little more tension on
the cable.
