Down elevator fbwa

Hello I have question about fbwa and elevator. My plane is quadplane tilt rotor. When plane is level in manual or stabilize the elevator is even at zero. When in fbwa the elevator is down a bit. It tell the plane to go pitch down but only in fbwa. it is like this on bench and when in air and through all throttle range. Anyone know what might cause that?

I believe it is trying to dive for airspeed.

Thanks that makes sense. Do you know is there a way to disable this?

Think I found it

STAB_PITCH_DOWN.

Will try tomorrow

Yep that did it fixed
