@AndrewGarrison I have came to a conclusion about wing stability and I think that you should add the stability modifier that's in SR2 that stops parts from snapping off this is a problem I face often when making planes that are big and making super sonic aircraft and sometimes when just making planes the wings just flop around and break off fro no reason. so I don't have to make all those improvises the "pros" make to make good planes thank you for listening sincely Yellow8041
