AddActorRotation On Two Input Events Causes Objects To Flip Out

Simple Pitch and Roll rotation using analog sticks causes actor to start ‘flipping out’. Why is this happening?

I have a Blueprint that contains a box mesh and a camera as a child of DefaultSceneRoot (images attached). Either input event defined causes the box to start spinning uncontrollably.

This setup takes literally a couple of minutes to test yourself Images are all below. This is a test I’m trying to use and educate myself on issues trying to make an airplane rotate with roll and pitch (like real planes turn) and I’m having the time of my life. So I figured I’d start here to try and understand why this is happening first.

I am using Engine Version 4.22.2.
