Just a few tips that are by no means testament:
1.) Viper is great for bounty work. Better shields but less hull than the cobra. Vice versa for the cobra. Both have the same maneuverability, but the cobra has more space and can serve as multi-purpose in a good way (missions).
2.) All lasers = no ammo costs. Cannons = high damage at closer range but require better shot placement. Multi-cannons = making you feel like one of Adama's pilots from the Galactica. Low ammo costs or no ammo costs is gooooooooooooood. Better for longer hunts.
3.) Gimballed weapons provide continuous damage if you can keep the bastard you're shooting at in the arc. Yes, fixed weapons do 20% more damage, but often make you lose focus in the fight; especially if there are asteroids present. Gimballed output less damage, but are excellent for destroying subsystems with continuous damage. Cannons drop subsystems like 3rd period home ec. Destroying subsystems = good tactics and faster kills.
4.) Know when to run away, and remember that the huge number of credits in vouchers are useless if you can't make it back to the station to turn them in.
5.) Shield cells are pretty much necessary for anacondas and the big stuff. Just remember that they use more power than the Griswald's Christmas lights.
6.) Chaff is like getting a french kiss from an angel during a dogfight if you use it right. Remember that it's not infinite.
7.) ALWAYS manage your power correctly. Shields don't run on hopes and dreams, they run on power pips
Engines aren't as important once you're on top of the other ship. However, Vipers will outrun you. Don't fight it. Just boost to them, shooting on the way.
8.) LEARN TO USE FLIGHT ASSIST "OFF." Pitching it hard and then dropping the training wheels for a second gives you a nice turn rate boost. You can also use this to do a g-flip turn. It's worth the time to learn this flight skill.
9.) Returning to the station for refitting can build complacency. DO NOT FORGET if you are wanted for dinging that pretty police ship's shield. They don't care for it too much. It's easy to forget, and the station may decide you're better as floating debris decorations for the mail slot.
10.) Remember that it's not as profitable. It's fun, which is why you play the game in the first place.
Happy hunting. I do alot of it, so feel free to ask me as many questions via PM as you like. Take care!
