How do I get components for air force?

Components are pretty hard to come by as there is not much option to earn them free. What you can do is to sell the airforce gears that you usually earn from your regular spins for airforce coins. If you managed to collect 7,000 airforce coins (which could easily take you a month), you can purchase a basic airforce component package. Take note too that the package would give a random component. Hope this helps!
