OK, here it is Lu, I will debate it one point at a time, if you like. I juast got back from a job interview where I flew the R44 Raveon. I was very impressed. It was not a pleasure flight so I didn't try to go into all the detail of your 'test' but I can sddress the following:
CROSS COUPLING OR PITCH COUPLING ARE ALLOWED IN THE CERTIFICATION OF A HELICOPTER BUT ONLY TO THE POINT THAT IT IS NOT UNCOMFORTABLE FOR THE PILOT TO MANAGE CONTROL. WOULD YOU FEEL COMFORTABLE TO FLY THE LYNX WITHOUT THE AID OF ELECTRONIC COMPENSATION FOR THE 15-DEGREE OFFSET?
BECAUSE OF THE IMPRECISENESS OF THE ROBINSON THE PILOT IS NOT EVEN AWARE OF THIS CONDITION BECAUSE HE HAS BEEN TRAINED TO PUT THE STICK WHERE IT WILL MAKE THE HELICOPTER FLY FORWARD OR ANY OTHER DIRECTION.
As far as control impreciseness, the R22 / R44 are far easier and more precise to fly than the large aircraft I have flown with the electronic stabilization off (Bell 412, Sikorsky 76A). So I must DISAGREE with this statement. Practical experience vs. theory.
There is nothing uncomfortable about where to place the stick to achieve forward or any other flight. I had not flown a Robbie in months and did not find any difference in basic control sense.
Therefore, I must conclude that in regard to YOUR satement quoted above, and in the argument presented in your paper, the facts do NOT bear out the theory.
Gotta go fly, I'll be back.
