Hang on, the tritium upgrade definitely has an effect of the sapphire. I think it only does the acceleration and not top speed, but there's definitely an effect.Prophet wrote: Nope, that correct. The tritium upgrade only benefits the freighter and only by 0.02c.
Simplest demonstration: Get a sapphire fitted with a tritium upgrade. Stop somewhere. Now hold down the forward and right buttons. Observe the nearly circular movement of the craft.
Now come to a stop again and turn off the tritium drive. Hold forward and right again, and watch your craft head off in a spiral pattern.
