I'm confident with the stellar service and safety record of the V-22 that an even more complex tiltrotor will be a standout success for the military.
The fundamental tradeoff with tiltrotor platforms is that you trade significantly increased speed for significantly increased complexity. What that means is your battlefield survivability goes up when dealing with any opponent with meaningful air defenses, but at the cost of increasing your "resting" accident rate when most peacetime accidents are consequences of maintenance and/or procedural issues.
Or I guess you mean /stellar?
