Changing the vector of the force according to the rotation

Hi, everyone.

I've been trying to create some sort of aircraft with two engines.
Engines and the aircraft are connected with a Hinge Joint, I use torque to rotate them and to roll the whole aircraft.
But when in the playmode I turn the aircraft 180 degrees, all vectors of the torques are inversed:
For example, in normals conditions I move the mouse forward to rotate engines forward and if i turn 180 and move the mouse forward again, engines rotate backward.
The same is with the roll.
What don't I know about the using torque?

p.s. attached the script and the package with the aircraft
