Just wanted to drop a message here, I’ve had my AM5n about 6 months (UK), but I started having issues about a week or two ago with my RA tracking: it started with slight spikes, until eventually it was just bouncing up and down like a yo-yo, but then after meridian flip, it was fine again!
It bugged me as nothing could be explained: it wasn’t windy, but I weighed it down anyway. Nothing was loose, but I tightened it anyway. I went through lots of trial and error but nothing changed.
Seen this thread, so during the day I decided to try fully rotating my RA on the AM5n back and forth about 3 times, then about 8 hours later in the evening, I set up my kit, and everything was perfect again.
