Repost from the other thread. Perhaps one of the simplest (vanilla) to orbit machines I have used. Presenting the newest MagTech Rocket, the Iridium-TR! Simple yet functional, this Iridium Class light lifter will put three Kerbal 'Astroneers'© into an orbit with sufficient fuel to bring them home, or push them to the great beyond! This two stage model model can reach a height of nearly 50km on the primary stage, and achieves 300km at 3300km/sec at second stage burnout, on an unguided vertical launch*. May this cheap model enable your future endeavors into the final frontier! *Note: Flight was stabilized. Flight reached a height of 1111K within 10 minutes. =>Usage notes: An initial set of decouplers will 'decouple' you from the launchpad. If you desire more maneuverability, jettison the previous stage at full burn, your ship will remain attached and in control (see pic). This also eliminates any massive slowdowns the game may or may not be suffering.
