Are you familiar with autostrut yet?
You have to enable advanced tweakables, and it basically makes any wobbly craft flyable.
no dont do it then green mans are not being endangerd and thats no fun :3
where is that in settings please?
When using Autostrut, I always set it to heaviest part BTW.
Which would be a fuel tank in the case of my rocket?
Unless you have royally screwed up, yes
Just did the Hercules V mission, testing out the Convert-O-Tron technology. Good thing I did that because I didn’t know I needed an ore tank. Did have radiators though! Bob Kerman is safe.
boo green mans are here not to life but to blow up in tens of thousend pieces
That’s better than me. I took waaaaay too long to figure out how to use radiators
You just put them on and they radiate the heat, correct?
You have to activate them either in flight or in the build menu
so you have to activate that and then they have higher survive chanche then i dont want that they need to blow up
