I am sure they did many takes to get the complete video. That is about as far from stock as you can get. I hate to say it but I would trade my Maverick for that XP1K in a heartbeat. That thing cost close to $80K to build!
There was a breakdown somewhere on that video. It was either 200 or 300 GoPro cameras used and they had 2 identical XPs in case something happened to one.
Also almost nothing on that thing was factory.
