If what the OP's video shows being done bothers you....then it is "you" that has the problem. Other than it being a Robinson....at least it was an R-44....I fail to see anything illegal in the video...or patently unsafe. Even the low level flying was done at a comfortable height....and it appears all heights were legal when near People and "things" on the ground.
I guess some folk just cannot understand that Helicopter flying can be "fun"...and safe at the same time.
It is not a matter of "Rules" being broken......but rather a "Mindset" that needs breaking.
Before you criticize you should first at least know what the hell you are talking about!
