Well dont get me wrong, I know how to turn tighter or generally how to fight in this game... also I have some good performance upgrades on my ship (except thrusters, couldnt find them anywhere).
I have also a pretty good combat flight sim career (IL 2 sturmovik etc.) so basically I should know how to dogfight (hope this doesnt sound narcissistic)
Flight sim experience may not necessarily help very much in space sim.
In Elite Dangerous I can easily dump direction of flight and change fire arc on the fly by suddenly dumping flight assist, or I can use thrusters to strafe or move vertically to shake the attacker. In flight sims you don't have those luxuries.
