Strike Eagle horizontal stabilizers not matching joystick movement

[104th_Money]

So I was in external view and noticed that there is a pretty decent delay in the movement of the joystick to how the stabilizers respond. At full rear deflection if I let go of the stick very quickly it takes almost a full second to return to the neutral position. I tried adjusting saturation and curvature on stick but nothing seems to work to give immediate control response. In the roll axis, the ailerons respond and return to neutral immediately.

Is this something they are working on or am I missing something here?

The F-15E has CFTs and a heavy radar in the nose so the center of gravity is unusually far forward for an airplane. So I would guess what you're describing is what the flight control system looks like while keeping the F-15E's massive pitch moment in control. People have noticed that the F-15E has a pretty bouncy nose and that pitch inputs are generally very sensitive. Maybe the flight model / flight controls are still WIP or maybe converting a fighter airframe into a bomber has some side-effects.

Maybe it is a CAS effect, try with CAS pitch off.

Was this on the ground with no airflow?

If it was, it is an effect from CAS. When flying all control inputs are instantaneous. Look on the input graph with Ctrl+Enter to troubleshoot input parameters. CAS and other similar systems moving control surfaces on ground tend do mislead what the airplane can do in the air.

Thanks for the responses guys. I will have to check that out when I get home from work. I never suspected that it might be something like that. I have had this issue in other planes but was able to take care of it through axis tune.

Yeah, a jet needs a minimum airflow rate through the AOA sensors for the flight control computer, the servo-actuators function might get a bit wonkey without.  You never want to have an aircraft on jacks with power and hydraulics on and no airflow over the AOA probes, it can jump itself right off the jacks when the controls start fluttering, they have that much momentum and can move that quick.  You always see the crewchiefs standing well clear once powered up, good way to get your head mashed in.

Hm, probably set the axis just how the airplane flys to you. The flight control system will make the flaperons flop all over the place trying to interpret your control inputs.

So you shouldn't be posting asking about how to set up your controls for the Flaperons, the Flaperons should be posting asking you what you mean when you deflect the stick in a certain way

@Czar66 Sorry for taking so long to get back to you. You are correct, in the air the control surfaces match the movement of my aircraft and the movements are instantaneous. Thanks for the help bud.

@Rudel_chw Thanks for the suggestion, I tried Czar66's suggestion first and it worked. Thank you for trying to help.

@Theodore42 I fly with no axis tune in the Seagle, same as with the Hornet. Full joystick movement and it seems to work fine...In the Viper I have max control surface deflection at a little less than half joystick movement. It is very sensitive but it just seems to work better in the Viper like that for me.
