"That could be the XT-60 power connector, I had a similar issue couple of years ago on an IRIS where power would cut off while you try to close the battery compartment, or if you wiggled the connector - luckily I noticed that when I was still on the…"
This happens a lot with my IRIS, especially on windy days!Just upgraded today to the latest beta FW, calibrated compass and acc, result the same.Remote mid point etc are also good.I looked at the logs myself, saw the EKF errors, not sure related but…
