Also, once both grounds are connected as needed, you will need to recalibrate the escs if you originally did it…"
"By using Loiter mode, you're having the software compensate for whatever the problem is. The fact that Loiter can compensate probably just means that the leveling needs to be re-done. You should be able to fly it in…"
