Well the Army may have some extra pennies in their wallet if the ARH goes south! Interesting design anyway. I would be interested to see if this evolves into some kind of "swing wing" design ala F-14 to get the wings out of the downwash at a hover. Of course that adds complexity as well.
Nick,
You said the swiveling tailrotor only gained about 20kts. I was suprised to hear that as the cheyenne was pretty fast using just a pusher prop. I guess I figured that a larger aircraft like the S-61 with lots of tailrotor authority would have a greater effect as a pusher. Anyway thanks for the info!
