What about putting 1 large atmo between the refinery/assembler and the forward area of the ship?

You can run small conveyor around [or over] the thruster to save space and still transfer ice, o2/h2, ingots, ore, and anything else that will fit through small tubes.

I would suggest to put the thruster on the rear but you still have the issue of how to place the other stuff once you remove it to mount the thruster.

Let me see what I can do myself and I will post them for you to take.

When I made these the main idea was for them to be really small. Two large Atmo thrusters are huge. :)

I would just add a battery and small non-mod reactor to ion type and remove line of small atmo thrusters and add 2 large atmo thrusters to the atmot type

Yeah, I have neglected these for a really long time... They could also be upgraded with my new cockpit and maybe even a couple of other things.
Their time will come, eventually. ;)

No power on ion type and not enough thrust on atmo type.

Fix(s) for ion type:
#1 add 1-2 battery
#2 replace reactor with non-mod type

Fix for atmo type:
#1 replace line of small thrusters with 1 large thruster
#2 remove line of small thrusters from center, move other stuff inward, add 2 large thrusters to sides

There seems to be something wrong with it and it doesn't spawn a reactor. I have been told about this bug but I haven't had time to check it out and fix it yet. I hope I can do that soon.

It just me or does the space version not spawn with any power?

New update:
Redesign of the Space version. Included my oxygen and hydrogen tanks, removed the vanilla oxygen tank. Added character tools, weapon and ammo + oxygen and hydrogen bottles.

I decided against adding the Enhanced cockpit concept for this version of the respawn ships. I might make a separate mod with it included. For this I prefer to only use mods that I have control over.

OK that's what I needed to know. So hand tools and bottles will be added.

http://www.spaceengineerswiki.com/Tools Basic tools for astronaut in some cargo container. for character sorry for my english...

Again, tools for the ship or for the character (engineer)?
The Enhanced cockpit concept would be nice. I might add that.

tools like drill welder etc how about adding Enhanced cockpit concept ?

By tools, do you mean hand tools or ship tools? If it's the second one I won't be adding any of that kind.
If it is the first, then I sure will as well as oxygen and hydrogen bottles. I realized I don't have any of those in. ;)

please add tools and enhanced cockpit concept!! best respawn ship on workshop ! thats what i need for my 1x survival game.
