Okay.. First off, this may be a repost of my own thread, if so, sorry. I am new to KSP, just got it on Steam a day or two ago and I love it! My question is this, sorry if I am duplicating <most likely I am, but my serch fu stinks lol>: 1. How do you duplicate the orbit of your target vessel? I can never seem to pull off 2 identical orbits, they always seem off set with one say being aligned with the equator and the second with a chase orbiter canted off where it passes above and below the target vessels orbit. SOMETIMES, I can get them nearly on the same plane, but never twice on the same plane. 2. Is there a series of practice launches I should make just to get the feel of it, or is there something I am missing entirely? Any and all help is welcomed, thanks in advance!
