I'm currently working out a loadout for my Vulture, which is a very light ship with high class (class 5) thrusters. It's a very light ship, weighing in at less than 500 tons at the absolute heaviest (in a very, very ridiculous setup).
Class 5E thrusters have an optimal mass of 560 tons, so even at its heaviest, the vulture is still well within that optimal range. Is there any real benefit to putting 5A thrusters on this ship?
