That one hit about 5950m/s, its just the one I used to test out orbiting because it's a bit easier to fly and doesn't take so long to burn all it's fuel.
I'm sure the big rocket I made could handle the extra weight of a parachute and extra separation module, but you can do powered landings in this game, I've seen screenshots of people landing their rockets on the launch buildings. It was when I tried adding stuff like 20 extra fuel tanks that it needed more power than I could put on it and still have it flyable.
Just tested it then, it takes off just fine with the extra modules.
