Depends, I always lean towards reality. The X-Wing started and stopped the rotor system 80 times in the America's largest Wind tunnel. This would have made it eventually an 800 mph helicopter. The program had it's money cut back for political reasons, but parts of it are starting to reappear in helicopters now.
This two of a kind aircraft, called the RSRA, had explosive bolts that could blow the blades off the rotor system, and fly back home like a conventional jet. That's not a model, that's the actual RSRA (Rotor
Systems
Research
Aircraft). The leading and trailing edge had a air grove that ran the full length of the front and rear of each blade. When taking off, high pressure air would be pumped out of the leading and trailing edge, creating a flap out of compressed air, this is called the Coanda effect. The technology you are looking at as so far ahead of the make believe "Star Wars" reality, in which somehow they have conquered gravity, yet, are the worse shots in the Universe, while this day and age marksman are killing people with a bullet from 2.5 miles away. I just wanted to bring some reality into the fantasy, to help people build better fantasy models. Science Fiction has shown the way for real products, the TOS Star Trek, and Tablet computers just one great prediction.
The "X-Wing works, it will reappear someday, just like the X-2, the fastest helicopter in the world, came from the ABC helicopter. It's interesting to note that the Raider and the X-2 have been developed solely from Sikorsky Aircraft funding, as is the Sikorsky S92, now the Presidential Helicopter. Lockheed and another company spent 100's of millions of dollars trying to make a new presidential helicopter to replace the venerable Sea King. They failed. Sikorsky offered the off the shelf S-92, which has set standard so high, it has become a new class of helicopter in terms of safety and capability. It saved us many millions of dollars. Canada purchased 19 billion dollars worth off them.
United Technologies just sold Sikorsky Aircraft to Lockeed Corporation. Sikorsky employs 8000 people or so, plus related business, in Connecticut. My God, if they left the state, this state would go belly up.
