I have decades of RC flying experience, and thousands of flights and thousands of hours of flying them. I have seen some impressive RC flying over those years, and I still was impressed.
You are looking at some very expensive RC aircraft there. And to get to that level it is very likely they have destroyed a few expensive ones over the years along the way.
Eventually if you stay at it long enough you may reach a level where a crash would be extremely uncommon.
You are not only looking at great flying skills, but great building and technical skills to get RC aircraft capable of flying like that.
