Genghis:
You're absolutely right, and there are some HUGE risks on this project, but fortunately I'm an avionics chap not structures.
We've taken a long hard look at the Osprey problems and are aiming to incorporate their lessons in our design - Bell have been struggling for years to get certification despite pausing their developement to learn the Osprey lessons.
Thanks for the other inputs - exactly what I was hoping for.
