Can someone please help me get this Tie Fighter to fly right?

In the video, the craft can be seen performing smooth and full rolls, the pitch however seems limited and not a full 360 degrees. Yaw seems ok for the most part. The ascend control seems to be working decent (more on that later).

But the forward movement is the main issue I wanted to ask about today. I admit I suck at math (lets get that out of the way lol), but this is a math question I’m not sure how to ask.

I added some vectors to the X positive and when I hit the right trigger it moves forward at a speed I am happy with (Based on what all I have seen of SW games over my life time.). But as can be seen in the video, yawing and pitching had no effect. And the forward movement needs to change based on pitch and yaw, and perhaps even roll. Not sure how to calculate that here. Any suggestions are welcome.

The other issue… was a gravity issue. I could not seem to get the tie fighter mesh to be effected by UE4’s gravity, so I made my own.

I doubt this is anywhere near 9.8 meters / second down, but I just eyeballed it till the tie fighter fell at a rate that seemed close. I added a small 5 second delay just to give me time to get to the tie fighter and Battlefield style “get in” the vehicle with my E key, and then quickly hold left trigger to activate ascend before my synthetic gravity kicked in.

Here is my going forward component.

And here is my simple solutions for
Roll

Yaw

And Pitch

The Tie Fighter is a fictional vehicle that is a VTOL (vertical take off and landing), I imagined the ascend control as a force always pulling up and away from the ground (no matter the orientation of the aircraft). A force greater than gravity. At the first of the video you can see how quickly it climbs until the gravity kicks in.

The right trigger is the main forward motion. I suppose I thought that would make for interesting Tie Fighter control, having to constantly balance this with the left trigger ascend control (along with roll, yaw, and pitch). Any weapons could be on the bumpers.

Any ideas, suggestions here? Thanks.
