Update 01.130
This one includes some good fixes!
-Ship movement is now server-side
Not having tested it, I would expect it to fix all the really weird behavior with landing gear. Hopefully not too prone to rubber-banding.
-Cargo ships are re-enabled
I disabled cargo ships a while ago because they were all crashing into planets. Then, Keen force-disabled them in worlds with planets. Now they're re-enabled and fixed! Cargo ships should now spawn in space, and not crash into planets.
For what it's worth I've played on the server for a few hours and had zero rubberbanding problems with the astronaut, so I expect ships should perform ok. I think the people really having trouble are the ones playing on servers with low simspeed, your server is pretty much rock solid 1.0 so I don't think it should have any serious trouble.
Also a warning to anyone playing on the server - cargo ships on means argantavis is on. He won't attack your stuff if you are offline but he will randomly spawn instead of a cargo ship sometimes and come for you if you're online. Last I played his drones were broken and didn't attack so he was no threat.... but that might have changed. So build some turrets if you're in space.
RE: nanite block:
On one hand I agree, this game needs more engineering and less magical all-in-one blocks.
On the other hand, we can already use welder walls to build ships but they make lag if you have more then a very small number, and require pistons (usually stacked on each other) which are still buggy sometimes. The nanite block is also surprisingly a lot more balanced - welders are basically free (mostly iron), use virtually no power, and build very quickly. The nanite block uses a LOT of power and builds relatively slow and (probably, don't remember offhand) costs more than a whole wall of welders. The nanite block also builds too slow to be very effective at self-repairing in combat and uses too much power to stack tons of them to make you invulnerable.
So basically, while ideally we'd have more engineering, I sort of feel like it's a good compromise given the current buggy/unoptimized/unbalanced state of the game.
Edit: I did notice some minor rubberbanding that seemed to be related to cargo ships spawning. Nothing too annoying.
