Drone stops during mission, floats around does not respond to RTL

Hi all, we have a few issues, see attached .tlog

  1. in flight one the drone makes a waypoint then goes back and starts over at the beginning of the mission (survey mission)

  2. in flight two the drone hits a waypoin then just starts floating down wind. It has full sats and reports no error still in auto mode

Any thoughts?

Thank you in advance.

the log didn’t attach unfortunately, please try again?

Unfortunately the forum will not let me upload attachments… here is a download link


Let me fix the forum bug…

I replaced the transmitter… it’s possible the TX was sending some jumpy signals? anyway all is fine after transmitter replacement.
