More parts than a Chinook, that’s for sure, even tho' the fwd and rear rotor systems on a Chinook were almost the same; just rotated opposite
Saw a Skycrane at Can Tho in ‘69. Impressive machine. Could carry “pods”; for instance used for coms, medical units, cargo of all types.
On lifting a load the pilot turned control over to the 3rd crew- member (typically an E6) that sat facing the rear in the back of the pod.
He operated the flight controls to hover over and pick up the load.
