Congratulations to the team on getting started on restrained runs!
As for some of the rotor clearance comments, I'm sure Bell did a lot of work studying that and I have no doubt the rotor will always clear the fuselage. The rotor to wing clearance is trickier since the blade flexibility will allow additional deflection even if the hub has flapped to a hard stop. Blade to wing clearance will likely always rely on the aircraft being inside a known flight envelope and predicted flap, yaw, roll response.
The exposed hardware when the nacelle is in VTOL mode looks vulnerable to bird strike... I understand that as a demonstrator, the certifying authorities might not require bird strike resistance. Something to address in a production version.
