Not a problem limited to the smaller machines. The BK117 co pilot's controls are easily removed, save the pedals which are covered with a shaped panel to protect the pedals from passenger's feet.
Only requirement is that the pedals must be put fully forward, otherwise they can foul on the cover. Needless to say, engineers removed and signed off the co pilot's controls. Pulling pitch, just as we came light on the skids, my pedals decided not to move any further

Quick dump of collective, two minutes work to lift the cover and slide the pedals forward, and off we went.
It now goes without saying that I now include a check of the co pilot's pedal position when the duals are removed
