Jack, in the second paragraph of your post #41 (which I think you were only quoting) there is some information I believe to be incorrect.
The AS-350 is certified in the U.S. under 14CFR27.
When it comes to a flight control activated by hand, 27.397 would appear to apply. This allows for 100 pounds (45kg) of force to be needed to move a control fore-and-aft, and 67 pounds (30kg) of force to move the control laterally.
This is, as you note, quite high.
