Advanced rotator and advance mover on a plane ?

I have the advanced mover and advanced rotator in a chip , on a plane/aircraft . Both are connected from the left and right sticks via splitters in to the ( am quite sure) right X , Y and Z axis ( left stick on 2 axis in the rotator and right stick in the other one of the rotator ) ( R1 on forward motion). But when I hold the right stick to turn right . It turns right for a little bit then stops . Then the plane acts like the axis are constantly moving , changing between ± and - rotations all around ,but I have tried with the local space on and off
Any help would be welcomed , thanks , btw dreams is amazing :)
