First off, I'm very much enjoying the add-on. Thanks for all your work!
I discovered it through CKAN and was well into a career save before I realized that CKAN isn't installing it correctly. A good chunk of the parts just weren't in the game and I didn't even realize it. Turns out CKAN currently installs it into GameData/ThorTech rather than the intended GameData/DeepSky/ThorTech. CKAN also misses DeepSky Core as a pre-req (though it is available on CKAN and does seem to install fine). Looks like this prevents some models from loading and parts never show up, even in sandbox. So in case anyone else is playing through from a CKAN install and missing, for example, the Razor VTOL WarpJets you're going to have to either move the files or download the add-on manually. Or maybe it's something wrong with my CKAN.
