I am a user of this mod over 1 year as well as the remaining USI. In the upgrade from KSP to 1.3, this mod stopped working, I explain: - When used in existing or new ships, it is simply impractical because it is not possible to stabilize in acceleration, making it impossible to launch or any operation in space. I have tried different approaches in the new ships, from the most usual and simple to the most exoteric, with no result. Those that already existed and that worked well, present the same problem. Can you help? Thank you
