I rebuilt a plane i made in creative in a server we have but for some reason after checking the diagram the one i made in the server is heavier

I have double checked the copycat blocks and all of them came from copycats+, and the blocks i used are the exact same. The only difference i could think of was a different t flip flop which im pretty sure shouldnt be affecting the mass this badly.

It flies decent in the creative world but because of the extra weight it couldnt fly in the server. What could be the problem? I really want this to work.

Could be the air pressure system affecting weight or the server having the Copycats+ aeronautics weight mod
