Well, just to toss in a (probably rehashed somewhere) idea, why not have some wings? Short wings like the X-49A, but I imagine it'd make it more stable, make high speed maneuvering better, and it gives a CAS/attack helo version using this tech a nice place to mount weapons on. If it improves range, makes it easier to land with dead engines, makes it more maneuverable or stable, and all that jazz, then why not? It seems like they have added stub wings to it at some point, but I'm interested in knowing why.
Feel free to flame me and pick it apart. Also, yes, I do not know the math involved.
