Hello, I just got the full version yesterday and I have been watching ALOT of Scott Manley videos. I am trying to make my first space station however I need to send it up on a 'lifter' I believe they are called. Pretty much what my understanding of a 'lifter' is, its some rockets that send a probe/satelite/ect to space or often kerbin orbit. I am trying to design a 'Lifter' separately to the space station so that I can stack them later and re-use the 'Lifter' on other projects. I have tried stacking them and it does not want to connect. I am not sure if it is with my design of the 'Lifter' or something else. If someone can help me out with design/what I need to do, or link me to a tutorial on this then that would be great. Thank you for taking your time to read this, Sincerely Bowan Whalley
