How about 'sloppy stick?
The Sikorsky S55 and the Westland Whirlwind version did not have any feel or opposition built into cyclic stick. There was a variable friction that one could try but it was unreliable and had a tendency to jam.
That then entailed keeping one's hand on the cyclic continuously. Let it go and the stick fell over and the aircraft followed it. Progressing onto later helicopters with artificial feel and trim requirements took some getting used to.
