So I've been looking around for size 4 thrusters, power plant, and frame shift drive. Coriolis.edcd.io says size 4 fits the ship, but I've been to about 4 different stations and the max I was able to find for those parts was size 3. Is size 3 simply the max and the site was wrong? Excuse me if I've made a mistake, I've only had the game for a few days.
