Rotate an actor(no character) around a planet

we are trying to make something like the choper around a planet like Broforce overworld

The problem is that we have not achieved to make the actor to look at the direction like** orient rotation to movement** option in character class.

the setup we have is
The planet is at 0,0 0
The plane is attached to a Pivot using a spring arm.
The Pivot is located at 0,0,0 too.
The camera is above the plane.

When we press Horizontal/Vertical the pivot rotates. because of this the plane attached rotates around the planet.

This works fine except that we donĀ“t know how to make the actor to look at those directions.
we tried this
without positive result
