Force versus movement for trim
Interesting about trim feel, and it could have played a role in Viper stick implementation.
The thing uses stick force per gee or roll rate, so it was real easy to trim off the control pressure to get a gee (gear up) or AoA (gear down). Max force was about 24 pounds in pitch and 16 or 17 pounds in roll. Neat thing about roll was the jet would command up to 180 deg per sec calculated aileron deflection at ZERO stick input to maintain zero deg/sec actual rate. This saved a jet and pl' Gums when one leading edge flap folded up on me after raising the gear one day ( see the pic in my profile bio).
So maybe force per aircraft movement could be emphasized for the 'bus.
