Best way for Helicopter Rotation?

If anyone's made a helicopter in their game before, I'd like to hear your input on the ways you made it rotate realistically in a side view. Note: the actual vehicle, not the blades - that's in an animation.

I have the helicopter's (not controlled by player) animation facing the direction of travel based on X velocity.
This works:
When self.movement.X is (equal to or greater than) 1, use right-facing animation
When self.movement.X is (equal to or greater than) -1, use left-facing animation
When self.movement.X = 0, use the last-facing animation (so it's still facing last direction of travel)

But when I add in rotate logic, it doesn't reset to the original (non-rotated) position.

When self.movement.X is (equal to or greater than) 1, use right-facing animation, and rotate to 335 degrees
When self.movement.X is (equal to or greater than) -1, use left-facing animation, and rotate to 25 degrees
When self.movement.X = 0, use the last-facing animation (so it's still facing last direction of travel), rotate to 0 degrees.

For some reason it keeps adding the rotation value, even when i have the Otherwise statement using a 0 degree rotation. so after a few passes of left and right, it's basically upside down or straight up and down.

Any pointers?

I've been thinking on this one for awhile, busy doing other stuff in the game.

Maybe I need a long set of rules so that the actor has time to rotate to angle and back to zero properly. Such as:

When self.linearvelocityX >= -11 <= -15 & rotate to 15
When self.linearvelocityX >= -6 <= -10 & rotate to 10
When self.linearvelocityX >= -1 <= -5 & rotate to 5
When self.linearvelocityX = 0, rotate to 0
When self.linearvelocityX >= 1 <= 5 & rotate to 355
When self.linearvelocityX >= 6 <= 10 & rotate to 350
When self.linearvelocityX >= 11 <= 15 & rotate to 345

you get the idea... i'll try this later and report back.

In my border patrol game i just made my helicopter scroll back and forth with the blades rotating not how you want so i cant tell you off the top of my head and tell you what your doing wrong. But im gonna play around with this now and im thinking theres a easy way to do this.
