Some of us are guilty of doing similar flights at some points in our careers. We lived through it, and that silly stage passed. We became better, smoother, more professional, more mature, OLDER pilots. A few didn't.
This guy s is probably not a bad pilot, but he did do something that some of us have learned not to do.
In my opinon, he did put the aircraft in a position that if the "known issue" of servo transparency developed, if only for an instant, he may have been in danger. That type of aircraft has been know to do that, so fly the type accordingly. Fly smoothly, and always leave yourself that exit. Flying agressively toward rocks could put you in a bad situation...IF something does happen.
