Anyone willed to help me ? [Create a Flashlight]

Hey, i want to make a FP Flashlight with a Deadzone, like in the Wii-U game “ju-On”, i never played this game so i dont know if the flashlight can be moved like that while a button is pressed or if this is the normal case.

For the case someone never saw a footage of this game, i tell you what i would need:

while the right RMB is down, only the flashlight would move in like 45° in each direction, depeding on mouse input of course. If RMB is released, set it to pawn rotation again.

I dont know how the set this up in a blueprint.

I know i ask for much here, but is anyone willed to guide me through this :S?

I have nothing to show you, so you could see that im really trying, but i dont even know how to start. I also know its a cheap excuse, i know i have to learn that kind of stuff if i want my things going to work. But i have some kinde of a learning weakness if it comes to complex stuff like those kind of blueprints.
It will take me alot of time to know how nodes are working or stuff are manipulated.

Ok new update, maybe someone can help me now, i tried it with the physicshandle BP, i thought i can manage this but i just fail -.-

So am i even close to that what i want to achieve ? Im realy lost here :S
