Ok, so I'm making this folding wing jet, and I'm almost finished.

The only problem is, the part that folds keeps moving around. I'm pretty sure I have to disable physics or something but I'm not sure for what.
Use modded structural wings
You can take my F-30's main wings if you want. No need to credit me.
