Instructions:
Upon loading up the rocket, push space or the staging key when ready to initiate the countdown to launch

At liftoff, the rocket has a script that will automate the gravity-turn (Credit to Zzazza's Automatic Launch System, as I reverse engineered the script).

At 5% fuel in the first stage, you can optionally switch off the inboard engines just like the real rocket but this isn't required. I couldn't get the script to automate it for some reason.

When the second stage fires, let it automatically adjust attitude to compensate for the low TWR, and when you reach orbit, cutoff the engine, then use AG 2 to seperate the CSM.

AG 1: Inboard Cutoff
AG 2: Sep. Spacecraft
AG 7: Abort launch
AG 10: RCS
Slider 1: Extend high gain antenna

This is the Saturn IB, AKA the uprated Saturn I. It replaced the Saturn I's second stage S-IV with the more powerful and efficient S-IVB. It was used to launch test articles and crewed flights of the Apollo spacecraft, including the CSM & LM. This one in particular I modeled after Apollo 7.

Requires the RSS Rebalance mod if you want to use this in RSS.

Saturn V (with the same S-IVB) will be released later.

    @Raymondhrdina I didn’t think of that, thanks! I’m sort of new to vizzy.

    For the 5% fuel left prior to staging, you can alternatively do a “wait until stage burn time < X” and then zero throttle
