the only way i could see anything like this working in the game, would be to use a sort of Osprey design based on the lerch. Setting it up so that pressing the airbrake key would tilt the engines rather than the entire aircraft. But that'd look really out of place in the sim Unless you just flew it around with the airbrake on all the time, which would probably be comparable in performance to the real thing.
Then again using that the lift would be coming from the centre of the aircraft and not the engines. And youve got to consider torque.
I recon a two rotor chopper would be too much for the game engine.
