Machine gun synchronizer in slow motion - GIF

[FEM2008]

ha...
I just knew those propellers stopped for every bullet.

The machine guns were synchronized to the propeller, so the machine gun stopped firing when the prop passed in front.
The one I did not expect is how close the prop is to the bullet path when the gun fires. I would have thought it would fire right after the prop passed in front of the gun, not just before.
