Hello,
I'm having a problem with the S-IVB. When it begins it's maneuver to the SEP attitude, it develops very high rates and quickly is in an uncontrollable tumble. Viewing the maneuver from the exterior view it appears only one of the APS units is functioning.
I'm not sure how I got myself into this situation, if I've made a procedural error or if I somehow re-programmed the S-IVB while playing with the RTCC (before liftoff I was trying to see if there was a way to change the launch time. I didn't think I changed anything, ended up launching as originally scheduled without the delay, but could I have inadvertently messed up the S-IVB?). I'm attaching the .scn, hoping that someone might find where I've gone wrong and instruct me how to correct it.
Thank you
