Greetings, We have updated thruster heat with the goal of significantly increasing the time it takes to overheat during normal use, with the goal of having it happen only rarely. Ships should still overheat relatively quickly when using afterburner. However, we have a lot of flight ready ships with a myriad of configurations. If you discover a ship that isn't operating as well as others, let us know below! -Baior RSI Player Experience Analyst
