...the closest is probably the German Army, which uses the BO105 as its initial trainer (likely to be replaced by the EC135 as the 105 retires).
German army uses EC135/635 for basic training. The Bo105 is only used for the emergency training block (autorotation).
I dont think it's a bad idea to use this level of complexity if you not are going to fly older 'analog' helicopters at all. You'll miss some of the handling training, like secondary effects on the controls.
A modern heli is supposed to be easy to fly, is it possible that it 'masks' a weaker student by being so easy to fly ?
