I had thought on the ESC and pointed to OP earlier but that should be the last thing to check. We can check if we upload logs and analyze motor currents in no wind condition when aircraft is hovering.That's a given, but what concerns me are the reports of no vibration, update, then vibration. Especially from those who have already balanced their props. I'd still like to keep track of new motors or old motors just in case there was some sort of ESC control change in the last firmware which we mentioned here earlier.
