Dear friends!
CSS 737-500 version 1.1.3 is available for download via the CSS Launcher!

In this update, we focused on improving the visual model, the operation of systems, and improving performance. Work on the CSS 735 continues every day, and we are determined to make our model perfect.

Due to the fact that we have significantly reworked the visual model, after the update you will need to reinstall the liveries via the launcher.

The official paintkit is available for download here.

For everyone who purchased our aircraft by subscription between 30.05.2025 and 04.06.2025, when there were server issues, your licenses were automatically extended until 05.07.2025.

We are currently continuing to work on improving performance, adding new features, systems, reworking the sound package and migrating the CSS 735 to MSFS2024. Work is also underway on the passenger versions of the 737-300 and 737-400.

Soon, PayPal will become available as a payment option in our Launcher.

Thank you for you support! Enjoy your CSS 735 flights!
