I give up

Just spent another hapless 2 hours and I'm dead within 30 secs everytime. I so wanted to enjoy this and I'm so rubbish.
I had the same issue, until i realised this isnt an atmospheric jet fighter simulator.
You NEED to strafe and move up and down.
You NEED to power manage between weapons, engines etc.
IE: Power to engines to close distance and get in close. Once behind or in the weapon blind spot of your target, begin manoeuvres to maintain weapon tracking (Using strafe movement/Up/Down movement and some mouse/joystick aiming) and push power to weapons for extra damage.
If taking damage put power to systems to help alleviate some stress while you conduct evasive manoeuvres.
For me, this game required some time and effort customising a lot of controls.
I use a basic joystick, a saitek cyborg evo and I use my hat switch as my power management tool. Thumb controls target locking and secondary weapon fire. right hand for pitch, roll, yaw on joystick and finer aiming.
Left hand on keyboard at WASD to control strafe Left/right and Up/down as well as keyboard based throttle, afterburner, lower power mode and other such misc functions.
Take some time with the controls get them comfortable, practice in combat and stop flying like you're in an F 18 jet. this is space, you can rotate while maintaining your vector, keep that in mind and USE that ability.
Good hunting dude!
