Alright. Bearings came in. Installed them. Now I have new bearings on motors 1, 3, 8. Also new props all around (the APC SF ones). Did a test flight. It flew pretty well, no issues. Motors look balanced right, so I'm not getting the reason for the temperatures on some of them (4 and 6 in particular). See below the GPX output. Let me know your thoughts please. Thank you!

Cris: I suspect the problem with digital sensors (like digital watches) is they create the illusion of precision when no such precision exists. Motor #6 at 64C is only 4 degrees (5%) off from the average temperature of 68.125C. Unless you have any other reasons to fret, I think those temperatures look just fine -- there's going to be some sensor error amount in there as well (e.g. why is Motor 3 showing a higher peak current, but a lower peak temperature). So I'd just go fly but keep a watchful eye out for significant changes in the data. Please remember to smile when flying so that everyone knows you're doing for recreational and hobby reasons. Andy.
