how To rotae a sub component mesh bases on forward axis input acceleration.

I did add AddRelativeRotation but had mixed results. at first it was spinning really fast and then I managed to get it to rotate to 90 degrees but it happend as soon as Applied forwards thrust input axis i setup. then it stayed stuck there :(.
Nothing I managed to do caused it to move in relation to what I was doing with the left analog stick On the game pad im using.
But ive seen this and am wondering if this in the answer

Eventually I want the Vtol thrusters ive attached to the Ship im flying to rotate as I apply more thrust on the HOTAS flight stick throttle Until at maximum thrust they are horizontal propelling the ship forwards.
