which of the setting you mentioned that would trigger the drone to fall straight from the sky without any warning on a clear sunny day???
Any and all of them. Hence DJI needing dat files to establish what went wrong. Or people on here that can analyse them.
So are you saying one or many of the default setting from a $1000 device would just make that happen without a warning?
Why are you assuming "i wont read anything and defaults will save me" actually will? Its not a toy. Its got a lot of technology yes but its not a sentient being. It needs calibration, it needs to know where it is, it relies on radio and satellite signals, it relies on the user giving it sensible fallback settings for the local environment. All of which are clearly stated in the manual.
That's BS. It did not hover, RTH or land without any warning....
So did you set and verify the home point as stated in the manual? Did you verify it had it on takeoff as stated in the manual? Did you set an appropriate return home altitude as stated in the manual? Did you check the smart RTH and sensor modes were appropriate for where you were flying, especially obstacle avoidance (as stated in the manual). Was the RTH mode set to home, hover or land or whatever is appropriate for the area? Did you verify a solid 12+ satellite GPS lock on takeoff before flying away? Did you verify it still had this lock in flight? What were the wind conditions? What terrain was underneath or around you? What was the ambient light for the sensors? Did you take off slowly to 30ft without moving it laterally to allow precision landing to record a layout? Did you then do the required check of the flight controls and aircraft behaviour in all axis before moving off?
All of these need consideration before every flight and do need to be adjusted. You cant just turn it on and go every single time. Those are all user requirements on top of sensors, calibration, monitoring and everything else that sometimes needs to be adjusted.
plus I flew with the same setting the night before all within the first 24 hours I got the drone.
Means nothing. A distance of 6 inches in takeoff point can produce interference some times. Winds change, ambient light changes, the RF environment changes.
Yes some (very very very few) dji drones like anything else have technical faults and can fly away or crash. But the overwhelming majority of crashes come down to user error or the user failing to understand, read or perform the required checks for it to operate.
You have the drone and have the device with the app on so have access to the .txt and .dat files. Post them up on here, someone can analyse them and let you know if its likely something you did or if its something the drone itself did. Then you can work out where blame lies. At the moment you haven't provided data either way to say if its a drone fault or a user fault.
Its not something you can take out of the box, assume default, change no settings and fly off without a care in the world. The manual is actually pretty good about the user roles required to operate it if read.
