Real helicopter pilots, current and former, are not really impressed. This thing really couldn’t be called a helicopter, which I suppose it probably isn’t being called.
When the Marines first brought in the Osprey they thought helicopter pilots would be a natural fit. Turns out that the flight dynamics are different and many had to learn the skills necessary to fly a tiltrotor. New pilots now are pipelined so that they don't have to unlearn then adapt.
The same can be said when helicopters first entered the services and fixed wingers were transitioned. The Osprey is actually more stable and easier to fly IF the proper skills are applied.
