Your problem is simple.
You did everything good except you dint notice that your engine rotates at the different direction witch means it shows -10rad/s
And your limiter says that when my engine goes higher that 25rad/s, imode will be 0.
Try to run engine in the different direction...
Or there's what to do to fix the function

All positive numbers make negatives and all < or > make different like form > to <. It will work i was using this for ages... You just need to understand what you doing. Following is not enough, the main part is understand it well.

Or you can just use "- scene.my.x > 25? {do this}:{else do this}"
I mean, you can put a minus symbol

Wow, that should of been a simple fix for me. Thanks for the help guys.

And vaidas I do get that understanding it is the most important part, not just copying scripts. But following your tutorial is what game me my knowledge about it now. I made my I3 engine work now, and I will very shortly be having this one working as well.

It was all thanks to your tutorials, they were a massive help and taught me basically everything I know now.
