Each plane can be equipped with up to 10 Modules, which can be applied and tuned for better performance. As you upgrade more technologies for a plane, additional Modules become available.

Each Module enhances a specific aspect of the aircraft, such as its engine, armor, agility, or damage. Modules are available in three quality levels:

• Bronze (basic)

• Silver (intermediate)

• Gold (advanced)

You can tune up each Module multiple times to achieve better results. Each tune-up produces a random outcome, and if the new result exceeds the current stat, it is automatically installed.

Installing all Modules and upgrading them to Silver or Gold significantly boosts the plane’s overall performance.
