Thank you all so much that's absolutely fantastic It's mostly just to see the structures inside to see how strong they need to be. I know Kronic has the internal frame and Tornado was a spinner, but are the others made by having the panels cut (waterjetted?) and then welded into a monocoque? And then obviously gearboxes made up and bolted in, a supply tank and two buffers? Then batteries, Wotty and cabling? From the looks of stuff I found on Google is Iron Awe the same and so on?
