Thanks for your feedback. However, I think this effect can only be seen with an example rig like yours and not in a real vehicle which is why there are so many working planes on the workshop. It is probably because of how the aerodynamics calculations are optimized. Because this does not noticeably occur in a real vehicle, it isn't considered a bug.

There are many users in the JP community who are confused by the strange behavior of WingSection.

They report rolling in seemingly symmetrical aircraft.

So I researched this, attached a clear example, and made this report.

It's not a problem that only occurs with my rig.

Indeed, many users have faced various strange behaviors in Stormworks, accepting compromises and glitches to submit their work.

The mysterious microcontroller attached to my rig is also a glitch that was discovered to solve the problem that a lot of users had when rockets did not fly straight.

It helped me in testing this time.

I'm trying to help reduce such bad know-how.

So I'm very disappointed with your excuse ("There is no problem because exist working vehicle in workshop!").

It's disrespectful to all workers who post their work.

Thanks for your report. Many Stormworks vehicles contain tens of thousands and this is a lot of data. So we have to model a simplified approximation for performance reasons. There might be some small amount of unbalanced force left over in some situations. This is very minor, and real aircraft don't come off the production line perfectly balanced and require trimming also. This isn't considered a defect.
