Anyone else experience this? My 5-in-1's wind cups sometimes spin, sometimes don't when the wind is blowing. There can be 10-20 MPH constant winds and the cups won't spin. If I take it down and spin them by hand, they spin freely and the bearings feel just fine.
I have it mounted 12 ft above the ground on the end of a pole. Another weather station (with different wind cup design) near it is 4ft above the ground spins proportionally when the wind blows.
Is this a problem with the design of the 5-in-1 wind cups, or something else? I would like to fix this and not replace it with a different manufacturer, if possible.
Thanks!
