Could someone suggest something to help my ship in Combat mode ? I feel I have missed something or dont know something.
Three things that I ended up doing that helped me out as a low-moderate skilled combat pilot:
1- Know when to fly forward and know when to fly backward. The Python is not a dogfighter, and anything with a decent maneuverability will out-turn her. Against more nimble targets (ie: Eagles, FAS, etc), go in reverse and let your enemy come to you. Use your larger hull and shields to your advantage and "face tank" the enemy ship. This also lets you pull pips from Engines to put them into System (I tend to forget, but a good pilot would). Basically, play by your rules, not theirs.
2- Pulse turrets on my medium hardpoints. Sure, they do less damage than gimbals, but I'm able to maintain damage on targets even when I'm doing the turning game. Then, I put high DPS/Cap Hungry weapons (like a beam laser) on my Large Hardpoint so that when I finally do line up my target I can empty the capacitor during the "pass". Just keep in mind Turrets are currently bugged right now, and you'd have to "reset" them back to "Target Only" in the system panel every time you enter an instance.
3- Dirty Drive engineer upgrade. I'm not sure if you're into Engineers at the moment, but I got the Grade 3 Dirty Drive Tuning upgrade, and even with the worse roll ever it really improved the maneuverability of the ship. I went to the Farseer lady to bump up the FSD, and just went ahead with the Dirty Drive while I was there. I just got the mats from writing down what I might need, and taking missions that rewarded those mats as they came along (saving the Commodities for last, of course).
