I am new, I just purchased the game (version 0.90) and joined this forum! So I decided to go into sandbox mode to get the hang of the game, and built a rocket to send it into the orbit of Kerbin. When I launched it (after doing the tutorials construction, flight, and orbiting of course.) I was not able to get a orbit no matter how hard I tried my capsule would go far above Kerbin and back like a mortar shot. Any Tips or rocket designs to help with this?
