Here ya go, OP. Every combat-viable ship in the game can rock with fixed weapons with a bit of practice.
I used to be a member of Adle’s Armada. Here’s a potted version of my (many times delivered) ‘fixed weapon lecture’:-
1. Fit a beam laser sufficiently small that your Power Distributor can run it continuously, ideally with as many pips left over for sys and eng as possible. This removes timing from the multi-tasking.
2. Practice on easy targets at first: think interdicting traders in an Anarchy.
3. Track the target with your beam.
4. If it feels that you are pitching too slowly to track, briefly use FA-off while (if pitching up) simultaneously applying down thrust. This should catch the target up. Consider eng pips.
5. If it feels that you are moving too quickly, reduce control sensitivities using in-game options and, if necessary, your peripheral’s own settings.
6. Fly backwards / forwards as necessary to keep the target in your sights. Learn how handling properties differ when moving backwards.
7. Use yaw to fine-tune and maintain aim. This is vital, I have yaw under two of my fingertips at all times.
8. Once proficient with tiny beam laser, move on to pulse laser then burst laser.
9. After burst laser, rail guns. The quickest way to learn rail timing is by binding a burst laser and a rail to the same trigger. The burst rat-a-tat will teach you when the rail will fire.
10. Then, weapons that require lead (fastest projectile velocity first).
Be encouraged - any pilot can achieve consistent accuracy with sufficient practice. I used to fly an 8 x fixed pulse laser Anaconda, later a 5 x Imperial Hammer Fer-de-Lance, now an infinite ammo rail Courier.
A lot of it as ever is down to flying hours.
