Do the Deluxe aircraft skins improve performance?
No stat benefit is announced; Bandai Namco lists the Mobius and Team Zvezda items as customizable cosmetics.
Confirmed explanation
The skins have mode-specific availability rules, but the official edition description does not attach speed, defense, weapon or MRP bonuses to them.
What is not confirmed yet
Final cosmetic menus could add presentation options, but no competitive effect should be claimed without evidence.
