Why change it? Because Bell is losing it's customer base. Eurocopter outsells Bell world wide. Several recent competitions haven't even allowed Bell to be considered, Bell 210 for example. Now the ARH is going to be taken back. The 417 program has just been cancelled. The Indian military recently dis-allowed Bell products from competition for lack of altitude performance. The EC-120 has totally taken the 206B market away from Bell. Two years ago Bell only delivered 7 new 206B-III's. Are you starting to see a trend here?
