It still a cheat, but you can tell yourself you sent up an orbital construction craft (and you could even do it several times to feel like you sent up the same weight over several missions).
Then (important) remove the first craft completely, or they will be trying to occupy the same space and time. Then edit your quicksave.sfs file and look for the two craft, copy all the orbital information from the first one and paste it over the orbital info for the main one. Then load up your main craft onto the launch pad (without docking clamps). You can use hyper edit for a ridiculously easy solution BUT it's one that will leave you feeling empty and like you've not really done anything.Īnother way, which is still very much cheating, but cos its a bit harder will give you more a sense of achievement launch a much simpler (but still very heavy) craft and get that into orbit.
