I did @SketchEmmerian

@Alessioliol aye sorry lol
Try making sure all your fuselage parts are dead centered. I've had issues with cockpits not being aligned right in the past. Another thing, try taking off the extra langing gears maybe

Hello? @SketchEmmerian

I got rid of as much crap as possible, and now it rotated the other way? Maybe the parts being at an angle is a problem? The day before this happened it flew perfectly and is basically the same, I got rid of the like 2 changes I made but it still rolled?@SketchEmmerian oh and here is the link: https://www.simpleplanes.com/a/S9zCQS/Help-v2

@Alessioliol When I test flew it, I saw how you had basically doubled the plane in order to make the bottom a different color. Maybe just haveing so much stuff coliding and clipping might be an issue? Try just getting rid of all the doubled up stuff

No, I think I got all of the connections symmetrical, this is driving me insane@SketchEmmerian

@Alessioliol Did you get it fixed?

@GLOWBOX lol ur pfp

Thank you @SketchEmmerian

@Alessioliol im gonna fix it

@Alessioliol Oh I haven't had the oppritunity to fly it yet lol, not at my computer rn. I do play on High Physics, though so it could be something to do with it. Another thing

Check all of your connections. Sometime mirroring the plane may leave some of the connections a bit scuffed, so I like to go through manually to make sure it's all symetrical

@SketchEmmerian is that not happening for you? I mirrored it and as far as i can see CoM is dead centre, however im on low physics (i need low physics or my ipad will be sent to another dimension)
so maybe its the physics? still dont see why it would make it roll tho

Wdym by it rolls itself? Have you tried mirroring it and checking it's CoM?
