you need to install Loader Redux, either trough game mod manager, or download it from mod portal

awesome thanks

I can't seem to find the loaders anywhere. They show up in blueprints that I've imported but no where in the craft menu or tech tree that I can find. Am I missing something or could another mod be messing with it?
