Salute!
I have a Dash-1 for the Osprey due to my previous life working on the Spec Ops armament features.
Although the motors interconnect to the proprotors, I would have to say that above a certain gross weight that it would not be able to land perfectly vertical from a hover.
Watched the thing during its climatic testing here at Eglin and it could easily land with 40 or 50 knots forward speed and proprotor nacelles up at maybe 60 degrees or so.
The thing that got my attention was the FBW system and the flight controls. Buttons and roller wheels on the stick gave you translation, nacelle movement to get to conventional flight or back to the helo mode , descent rate and such, while the rudder pedals commanded yaw.
An Xbox or Nintendo dude could prolly fly the thing with zero hours in the real thing.
Unlike the Chinook and other twin rotor birds, the side by side proprotors produce some nasty vortexes that have caused some accidents. i.e. you lose some roll authority and even some lift when close to the ground and moving slowly.
Gums sends...
