Flyable Space Game Control by mouse position on viewport

Hello there,

i am new to.. everything.. i am trying to make a little multiplayer game refresh from a mod… so i got information, models and all this, just have to progamm how to use it.. So my problem is that anyhow i try, even all ki/ai i tryed failed to help to make my spring arm working in Space. Means sometimes is upside downside and right still have to be right if you put you mouse to the right side of the Viewport.. also if you look straight up and than you want to change to left, at the moment it starts to roll still looking up.. sometimes i am that far, that loopings works, and all this, but if i look straight right or left the viewport is in the first time making a little angle just in the first time and than the cicle is not where i put the mouse and everything goes wrong… I just use Blueprints because i can not use C++… so i just floats for the ship power to turning and rolling and put this in add Local Rotations.. this works the best so far, but than i have alywas the wrong angle stuff if i go left or right and the viewport what you see is angled.. by just going right or left, dont make scenes.. Attached i send a screenshot of the build how it nearly works, just the ■■■■ angle when right or left, but loopings works.. all 3 Inherits are false, Later i let the ship follow my cursort but first the spring arm have to work.. Please help me with this.. also Quaternion do not work. also vector stuff do not work. Eben with each a make rotator do not work..
