Thank you for your quick answer, happy with your explanation.

First of all i don't know if i am in the right categorie for a topic about bug reporting, so thank you to notify me if i am not. I made a car, and there is a kind of very important drag create by the wheels on the right side of it and none in the left side (as you can see in red on the screenshots). Because of it, my car is turning (which is normal if we consider those aerodynamical pertubation) but i've already check thousand of times and rebuild the car, always using the symetrical thing but the problem still here even with no difference betwenn my left and right side. If it's a bug, i'm happy to contribute to the good devellopement of the game, if it's my fault thank you for telling me what's wrong for informations i'm running KSP 1.2.1.1604 on a laptop with Intel core i5 processor and a nvidia GEFORCE 710m http://imgur.com/a/NP5yy (screenshots) https://www.dropbox.com/s/7s5c5vbwadjvr4k/Report bug.sfs?dl=0 (my save) https://www.dropbox.com/s/ctyxi70lcyou85h/Roulade.craft?dl=0 (the vessel)
