The rotation doesn't work at all

Hi. I’m pretty new to UE4. I try to use [this tutorial][1] to change TwinStickExample project to learn Unreal.
But when i try to change the rotation of the TP_TwinStickPawn using “Q” and “E” buttons smoothly, rotation of the camera doesn’t change at all.
Should i change rotation of another component in TP_TwinStickPawn?
The blueprints attatched here.

I disabled visibility of ship mesh component previously, so i couldn’t view the rotation of pawn. The pawn rotates correctly but i want to rotate camera instead.

The problem solved when i changed the Actor with its camera component and change setActorRelativeRotation with
setWorldRotation node. Now the rotation works correctly.
