    Right hand tail control:
    clamp01(Activate1)*PitchAngle + Pitch*0.85 - PitchRate/50 + (clamp(((Pitch)*(clamp((Roll+RollRate/130),-1,1))),0,1))

    Left hand tail control:
    clamp01(Activate1)*PitchAngle + Pitch*0.85 - PitchRate/50 + (clamp(((Pitch)*(clamp((-Roll-RollRate/130),-1,1))),0,1))
    .

    I made it for a V-Tail, but it works on normal horizontal stabilizer as well

    @overlord5453 I see
    That could help
    Alr thanks :>

    @Icey21 ohhh. So you have pitch and roll on elevators? If yes, you will have to limit roll on each side to just one direction. For example, when you roll right, only the left elevator moves and when rolling left, only the right elevator moves. You can use clamp() function to do that. It's a limitation with game itself.

    @overlord5453 Yup. Like when I pitch then roll but my AoA is higher than -10 (pitch up) then my aircraft rolls in the opposite direction

    Roll instability as if rolling on its own without an input?

    Tweak those values until it works
