Me thinks you give up too easily!
Take a look in the unusual RC section, there's plenty about the Osprey and other VTOL aircraft.

With electric motors it should be easier than with engines if you can get the power to weight ratio. My approach would be to forget the cyclic too, that and the gear to connect the engines (which you don't need with electric) is what causes all the hassle.
Just treat it like a twin and try some test flights with the engines facing forward. Then experiment with turning the nacelles to achieve STOL flight. You probably won't ahieve a perfect hover though as that's where you'll find the stability problems.
