Ok. the first thing i thought that was from the cock pit veiw which i prefer from it was really hard to see enemy's so i removed the gray hull front things. this made less detail but boosted he overall performance from my prospective. also i filled the gapes were the core is and filled with hull and more shield. also removed the missils and put over drives. finsly i added more AMC's were the missils were in the tubes. this is only a few things i did to soot me. but the evan without the thins i did its perfectly good for battle and tranceport + i love the shuttle thats a really good idea for it. hope this helps bye :D
