here's an interesting question what takes more resources belts drones or trains probably drones I think, because if you're looking at like how much, okay when- I had a similar question the other week and I'm gonna give this sort of similar answer if you're thinking of like one belt length versus one drone versus like one train card then I think drones are the most expensive for sure and then probably because the thing is like the problem is when you're building a lot of it right if you build if you build a hundred, belt segments versus if you build a hundred drones same thing like the drones are gonna consuming it but if you have like 10 drones and you have like thousands of belts the belts are going to be the most expensive part in the factory you know so it all depends on many things yeah you're only building a few drones compared to like thousands of belts
