We’re having a weird behavior YAW that causes the drone to incrementally spin in YAW, ending up on a crash (controlled crash as best as possible… ).
• Electronics: custom PCB Board
• Autopilot: Cube Black
• Motors: TMotor or E1200
• Mag: Magnometer icm 20948
• GNSS: ublox f9p
• RC Controller: FrSky or Herelink RC
I’ve made a summarized table of the flights, and annex all the flight logs.
The only component that seems to make a difference is the Herelink RC, which is the common element to all crashes. However, there seems not to be any problem between the channels and the motors.
We have looked into the logs as best as we can. But we haven’t reached any conclusion with the setup that caused the crash. If anyone could have a look at the logs and share your ideas it would be incredibly useful.

Flight 8 - Slightly larger because we performed an autonomous mission. By this reason I’m sharing a wetrasnfer link - https://we.tl/t-2GY20RULM1
