Those objects scattered around the frames of the 388 remind me of the early Dragonfly helicopters. In Borneo we had an aged Flt Lt called Charley Verry who had flown these in Malaya during the Emergency.
The first S51s did not have hydraulic assistance with the controls. This made them very heavy to fly with no means to trim them out. As he said. "You could always tell a Dragonfly pilot by the way he dragged his knuckles along the floor." In flight it was much the same so as to make it bearable there were loops of bungee attached to various points around the glazed front end. Once in the cruise one selected a convenient loop and wrapped it around the cyclic to offset the forces.

A 3 bladed fully articulated main rotor head was installed on the S-51 helicopter. The rotor diameter was 48 feet on helicopters and 49 feet on helicopters with all metal blades and controlled by a mechanical control system and a bungee trim system to reduce pilot fatigue. A rotor flapping restrainer was optional equipment which allowed rotor engagement in higher wind conditions.
A hydraulic servo system eliminated the bungee trim system in late production helicopters (H-5H) and was offered as a retrofit kit for earlier models. Hydraulic power for the servo was provided by a hydraulic pump belt driven by the tail rotor driveshaft.
They have no idea how easy thing are nowadays.
