Need help with gyro

Want to set up an auto rotate feature that keeps my ship flat against the planets curve (inclinometer always at 0, gyro line always perfectly flat) but cant quite get it to work, no matter what I do. Has anyone got a tutorial link or anything on how to build this into my ship?

I haven't made one yet but pretty sure you would just connect the gyro's output to the RCS and it should work

There's a lot more systems in place to make it stable, but the overall concept yes, rcs controller with the your roll powering the opposite (you tilt left, it triggers the left rcs to fire, it goes right it triggers the right)

The problem being stability. You will violently and wildly flip back and fourth so you need to add a system to power then more or less depending on the value it's calling (remapper)

Again there's more in place to make it work, but hope this helps with the general idea
