Hi, just thought about a way to improve available tech and parts, apart from science requirements. As in real life, the more money you invest in developping a part, the best it gets (less weight, more power in engines, cheaper to produce, better torque, energy efficiency...). So a part wouldnt get it optimal (and final) form untill some money has been invested in, AND some trials have been conducted. For instance, the same cockpit could be "lightweighted" from the 1st time it is used to the 5th, meaning that the engineers have found some improvements to make. Any ideas or opinions?
