Just saw the information on the mods that Piasecki is making to the Blackhawk - small wings for lift instead of just hard points for ordnance, and a ringtailed pusher propellor instead of a conventional tailrotor. Speed jumps from 150 to 225 and range triples. MV-22 performance is claimed at a fraction of the price. Does anybody have any knowledge of this? Saw it on both the piasecki website and aviationnow.com
