Just yesterday I was doing some experimenting with fighters. I would take a fighter and add only one engine to it. But strangely enough, adding the regular Fighter Engine makes it the fastest, and adding the Fighter Engine III makes it the slowest. Similarly, adding two regular engines makes it slower than simply having one engine.
However, in creating fighter with something else on it (such as a weapon), the Fighter Engine III is the fastest.
What’s going on here? I first noticed weird things happening when I was designing a fighter with a bit more meat on it (armour, weapon, etc.). I wanted to make it go faster, but adding a second Fighter Engine III would slow it down. This doesn’t make much sense to me. I feel like the formulas to determine thrust are broken. Adding more engines should add more thrust, even if the ship is slightly heavier. It’s thrust to weight ratio is not decreasing, and we’re not taking into account air resistance, so why would the total speed of the spacecraft decrease?
Has anyone else noticed this?
