Hi!
Quadcopter, 13 inch props, AUW about 2 kg, Holybro Pixhawk 4 Mini FC, ZED-F9P GPS receiver, 4.03 firmware.
Quad is a research prototype for automated cell tower inspection.
In last flight copter have crashed into tower shortly after mission start. Pilot tries to take cotntrol, but it was too late. Previous flight in same place with almost
same flight plan was absolutely flawless.
The only problems i found in log is a rising divergence between PSC.X,PSC.Y and PSC.TPX,PSC.TPY, wich i can’t explain.
I can’t see anything obviously wrong up until the crash - mechanical failure maybe? These logs are hard because its difficult to tell the difference between something going wrong and hitting something physically
Just out of interest, do you use some kind of RF shielding when flying around the mast and what distance do you fly from the mast?
Could it be that you flew past a microwave antenna and had interference on the ESC’s that is not logged by ArduPilot?
