Thanks Neon but I'm cool- my concern was for our younger (or for that matter any) of our community who may be unduly offended by the language. Chun apologised for his language, something a lot wouldn't do so it is more likely he was just exceptionally frustrated with his predicament rather than being a grub.
We are passed that, I wanted some clarification on the basic facts and we got there.
The AC crashed after Chun performed a CSC.
@Chun So that we might assist you in any warranty argument that may eventuate with DJI the following detail might prove helpful;
Did you loose connection between the controller and AC?
What was your battery level when the event occurred?
Where was your home point recorded?
What were four RTH settings?
What version of the GO app were you using?
What did you actually do in an attempt to cancel RTH?
We're all the propellers attached when you recovered the AC?
The flight log from the app will likely contain some valuable clues?
Where did you perform the most recent compass calibration?
Where were you flying? What were the conditions, particularly wind speed?
How fast was the object being tracked moving?
How many satellites were recorded, was the AC in ATTI mode?
The fact you performed a CSC won't necessarily mean this is on you, particularly where it is evident a DJI hardware/software cause made the AC uncontrollable.
If you go to healthydrones or phantomhelp thee are step by step instructions on obtaining and uploading your log file.
Plenty of people here will assist you if you want/need assistance in analysis of the flight log.
