I´m really not sure the BO105 pilot was Chuck Aaron. I can`t tell he is piloting for Red Bull outside northern america. I also not sure he`s the only aerobatic helicopter pilot in the world......
Rainer Wilke, a former german heeresflieger BO105 pilot, is a very active and well known helicopter aerobatic pilot....and he`s also licensed for the these crazy things. Rainer Wilke is part of the flyingbulls team, the european redbull aircraft team, station in salzburg austria. Most of the aircraft, heli`s and fixed wing, shown in the video are part of the flying bulls.
I believe Rainer Wilke ist the pilot of the BO105CB`s in the video. The flying bulls own two of these helicopters. The BO105 CB was the original version of the this aircraft used by german police, german heeresflieger and others.
Later, there were introduced stretched versions (BO105 CBS-5) with providing more space in the cabin and modifications on the rotor system. These were often used for EMS. I believe Chuck Aaron flies one of these streched BO105 CBS-5`s for RedBull.
Rainer Wilke did a lot of aerobatic flying with the BO105 for the german heersflieger back to the 1980`s and 1990`s, long time before he started a new career piloting for RedBull.
