Good to know it's working well, apart from the boot ! The 135 is, after all, the Bolkow replacement aircraft, rigid head and all. It seems a natural choice for that kind of operation. The 902 I'm sure will be equally able given that it is designed to be the "perfect helicopter".
It's not always the obvious problems that become issues in a new helicopter in a different role. On paper, they look the part, like buying a new car. But then strange things happen, minor little insignificant things start to become a real issue. The 139 on the SNS is a prime example. It had it all on paper but in reality, when flying a offshore for 8 hours a day, things became apparent that took a long time to solve. C of G problems with the offshore kit fitted . Fuel and range issues. etc. New roles test parts of an aircraft like never before. A bit like us when we do something different, muscles hurt you never knew you had......
