Hi I recently purchased a Phantom 4 (17th September) and have flown it at my local clubs fields a few times over the past week. My first Phantom was the FC-40, prior to quads I I had been exclusively flying CP (Colelctive Pitch) Helicopters . When viewing the log files in the DJI Assistant 2 application I noticed a log file dating back to 27th May. Is this a test flight by DJI? Is there a way to view this log?
