Right click the rotator pin and click Split… if no one said this already.
Re the rotation, I have a good feature you can add - idle camera spin.
Add a child actor to the drone BP, shove a camera inside the child actor class and configure it to taste.
Add a rotator component and parent the child actor camera to the rotator - then parent that to the drone. (don’t forget to adjust the rotator’s settings so it’s not spinning out of control).
On idle (if no control input for longer then 10sec works well usually) - transition to the camera that’s already rotating with the rotator.
On any input, transition back to the default camera (which should also be a child actor so you can avoid snapping).
