I have tremendous admiration for KSPI Extended, and I really like using it. I especially appreciate all the different models, the sheer diversity, and the modular reactor + nozzle + generator scheme.
However, sometimes one just wants to fly around in Heinleinan / The-Expanse-ish torchships. So I begin to wonder about a "KSPI Lite" edit -- based on my limited knowledge I think this could be done only with cfg file edits... or Modulemanager patch?
I went digging through my cfg files trying to figure out what one would push and pull at to achieve something like this , but I have not gotten very far.
