Force isn't using local coordinates!

I’ve been having the same problem for ages! I am using rigidbody.AddRelativeForce to create a pushing force for my aircraft, however it is not using local coordinates! I’m using (-Vector3.forward * 150) and if I turn my aircraft it continues to push in the original direction. Eg. if I turn 180 and face the way I came, the fore now pushes be backwards! It’s really annoying me, as I have tried everything I can!

Here are the bits of the script that are relevant:

The force pushing my plane -

if(Input.GetButton ("Throttle")){ //Throttle is increased

            rigidbody.AddRelativeForce(-Vector3.forward * 150);//Force pushes forwards

        rigidbody.drag = 0; //Cancels Drag


The torque that turns my plane -

//Roll right

        if(Input.GetButton ("Roll Right"))


        //Roll left

        if(Input.GetButton ("Roll Left"))


        //Pitch Up

        if(Input.GetButton ("Pitch Up"))

            rigidbody.AddRelativeTorque (65,0,0);

        //Pitch Down

        if(Input.GetButton ("Pitch Down"))

            rigidbody.AddRelativeTorque (-65,0,0);

Help would be really appreciated!

Instead of using Vector3.forward (which is global), you should use transform.forward. I had this problem a few days ago. Hope this helps!
