Viewing the photos of the flight (which were accompanied by all of the "best ever" required comments to get the bonus) I would suggest move the pilot station to the back cockpit and use vertically challenged pilots to avoid a decap during maneuvers.
The Sultan
@The Sultan (post 333) - what sort of flapping hinge equivalent offset are we looking at ? Would it be in the region of about 50% of rotor radius given the fact that the designers appear to be sufficiently confident of seating the Chief Test Pilot so far upfront !!
Notwithstanding all that, the X-2 is definitely promising - will hopefully prove to be the long overdue bootstrap for chopper designs from its present stagnant state.
