Dear Ironclad
Please do not tamper with the capital ships unless you are making them even more realistic, cap ships move in a ponderous way because they are big and massive, they shouldn't move like nimble fighters turning on a dime. Take the time to review those cap ships on Babylon 5 and you will see that even with the advance gravitic drives of the Minbari all ships move according to Newton's laws which means that cap ship move like the cap ships on the high seas
