I have to say that I like the V-22 Osprey for the idea and the possibility that it presents. But one question, it seems to me that with rotors/propellers that size that if one engine should fail. The aircraft would be highly unstable or even uncontrolable since the other would create to much torque or turning tendency the could be countered by the airfoils. So my question is, is the aircraft flyable with a single engine, or is that also cut and glided to the ground.

The V-22's engines are cross coupled by a shaft through the wing that allows one engine to provide power to both rotors. The V-22 would obviously have less power in single engine operation, but at least both proprotors would have some power. I've read that the V-22 also has some limited autorotation capability as well. I say limited since the rotor system isn't quite like a helicopter's so the autorotation performance isn't as good.
