Have to disagree with riffraff...the Rotodyne was actually very simple technology...no complex transmission,simple rotorhead and the tip jets were switched off after transition to forward flight when the noise ceased,and the rotor free wheeled,providing added lift to the short wings. Simpler than the tiltrotor and incidentally both BEA and Okanagan were interested in in the unbuilt larger version for intercity travel....and Kaman also wanted to be the US licence holder.
