I did at one point have a computer bit it couldn't handle KSP is all it's awesome glory I may end up going back that route. I'm hopeful for KSP2 in a year or so.
OK so let me pick your brain a bit, unless you are also using mods then this question won't really apply, but I'm considering using what I have been seeing called reaction wheel props. How does one build that kind of prop? Is there a piece that will attach the wheels to the sub and still allow them to spin independent of the main sub body?
