I was more familiar with the Army version....which in those days...helicopters were considered more in line with Jeeps and Trucks than aircraft.
The CH-34 had "ASE" , and auto pilot system with a Barometric Altitude hold feature....which did not find its way to the Huey or Chinook. It is no surprise the HUP was far better equipped than the H-25.
As in most helicopter designs of the US Military....there are many different models of the same aircraft.
