46Driver,
I met Jay Carter at an FAA gathering and hear his talk. Lots of interesting stuff gong on at his shop, too novel to be assessed based on conventional helicopter methodology.
Looks like a difficult job ahead for Cartercopter as it pushes through the Mu-1 barrier (meaning when that retreating blade starts going into reverse flow). My hat is off to those like that team who push technology in new directions.
On the plus side, if it all works, high speed transport with short takeoff runs is possible. On the negative, if it works, the traditional helicopter missions (rescue, rig transport, troop lift and such) will probably not be accomplished by that machine very efficiently.
