For now, I'd stick to using this design in space, and maybe on moons.

Thanks. Yeah, I realized recently that you need a crazy amount of thrusters to lift a full large (small grid) cargo container. Looking back on this design it doesn't make sense to have that large of a container, you'll never be able to fill it. I made a new design specifically for heavy lifting. The ship is larger, but it actually gets the job done. That one should be posted today or tomorrow.

I might revisit this design and swap the large cargo for a couple mediums, and increase vertical thrust. Would balance it better.

I really like the look of this little hauler. It's well put together, with everything connected properly. It's also simple to build with a welding platform. The only problem I ran into is it cannot take off from Pertam (1.2g) with a full load of cargo (steel plates). It also uses hydrogen extremely quickly, so I'm not sure it would be able to escape the gravity of Pertam even if it could lift off the ground fully loaded.

Anyway, I thought I would mention this because I really like the ship, but it seems like it needs a design tweak to give it more thrust and possibly larger hydrogen supply. Great look, though!
