I know these choppers and their scheme from my childhood. Everytime i heard a chopchopchopchop, i went to the Helopad and watched them. I was so exited! Thanks guy´s! I appreciate your comments very much!😄

Hahahaha. Like you Holger, hearing the sound and rushing out to see what it was. 🙂
But I ended up with a crook neck from watching all the traffic in and out of the old Brisbane airport before the Boeing 'jet age' happened, watching all the C-47's Dc-9's and super constellations from the end of the runway for hours on end. :-O . hahahaha :-
