OK, I relooked at the video and a number of questions came to my mind.
1. why did it take off from a taxiway and not from either the runway or a helicopter landing pad?
2. for a first flight why was there no flight data probes? surely you would want to know the environment that the aircraft was flying in?
3. Why did they not list the airport that they took off from, every other first flight video tells you the time and date and where the first flight occurred? Was this flight legal?
4. When it took off it had aGoProo mounted at each wing tip let later on in the video there was one missing, did it loose a GoPro if not was it the second flight that we saw later on in the video?
To be honest there are too many questions and not enough data to make those questions disappear.
