CEFOSKEY,
You are probably correct, in that the complexity etc. may not justify any possible advantage.
The idea is from the Department of Demented Designs.
It is one of many considerations for directing sufficient air at the upper quadrant of the propeller disk on the
UniCopter concept. This problem may not be so serious on the X2.
The X-wing is a good looking craft. A stated objective in one of the patents was
"to provide a stopped rotor X-wing aircraft with low drag and high speed forward flight, including aerodynamically efficient supersonic operation;". It appears that the craft was flown on its wings, but never flown with the rotorhead attached.
