The first HOKs were delivered
in April 1953 with the last Huskie being delivered in December
1957. The inter-
meshing rotor system on the Huskie made it extremely stable in
flight and particularly in a hover.
The front of the Huskie was constructed almost entirely
of Plexiglas providing an excellent view for an aerial observer.
With the removal of the copilotís seat the Huskie could handle
two stretcher patients, and sometimes an attendant could be
added. The HOK
served primarily as an observation- utility helo.
The rotor blades on this helo were made of wood and
covered by a cloth- fabric. Directional control was provided by
the servo flaps on the blades trailing edges.
