Errmm How does this work?

I'm having somewhat inconsistent performance. works perfectly on some grids but not others. i use several modded blocks, including thrusters and cockpits. i assume it has something to do with that. any guidance you can provide would be appreciated.

can it interact with with boat parts ship propellers? or does it need to be updated to handle that?

Any chance of being able to toggle this? I would like full control over speed in space, with throttle in atmosphere.

Update: Thrusters now fully stop when "Stop" is selected
