Although more information can be obtained from the .txt log there is enough in the AirData .csv to conclude that the Avata probably impacted the ground. The last record has the ultrasonic height sensor showing a height of 4 m, descending at 4.11 m/s with a forward velocity of 11 m/s. The video and Google Earth both show the Avata approaching the leading edge of a ravine or small canyon. The forward and downward velocities could have carried the Avata into that ravine before crashing. I know you searched the area but often crashed drones can turn up after multiple searches. I've outlined a possible search area.
The fact that no RTH was recorded is consistent with the Avata crashing. At time 279 secs the link was lost and RTH was successfully recorded. The last record (time 384.7 secs) has no RTH recorded, just the message "Image transmission signal lost Image transmission signal weak. Adjust antennas and make sure they are perpendicular to flight direction of aircraft". The ""Image transmission signal lost" message was also seen in the video you provided. Unknown is if the FailSafe was still RTH as it was at time 279 secs. The .txt would tell us that in addition to other helpful data.
