CSS News - August 29, 2025
Welcome to another edition of the CSS Weekly Blog where we keep you up to date with our latest developments.

Systems

Good news for old-school radio navigation fans - we've finally fixed the RMI! It now displays the correct heading, correct bearing and proper switching between VOR or ADF bearing.

We've also fixed a bug where reverse thrust wouldn't work under certain conditions, as well as some ground engine thrust tuning.

As always, our Testing team will have a go at the new build first, and we'll be expecting prompt feedback from them.

Exterior Modelling

Our Modelling team is continuing work on the 737-400 external model, which, as mentioned previously, is being done from scratch. This model will serve as the basis for the entire CSS 737 Classic Series lineup, so it's incredibly important for us to set a proper standard with it.

At the moment, the team is working on the most difficult part of the model - the wings. It's too early to show them just yet, what we can show today, however, is progress on the horizontal stabilizer.

You might notice a significantly increased level of detail - for example, we've implemented various hinges, pulleys and gap seals, while the airfoil is now more aerodynamic and true to life.

Once the new Fuselage model is completed, the vertical and horizontal stabilizers will be attached to it at proper angles and cut for proper length, which is why at the moment they might appear longer than they actually are.

Interior Modelling

We are continuing to rework elements of the cockpit, and today we can show you some progress on the Throttle Quadrant.

As mentioned previously, it has been remade from scratch using photogrammetry, which ensures proper sizing and proportions of the model. The level of detail has also gone up, and we're modelling all visible moving parts for maximum realism and aesthetic pleasure.

There is still a lot of work ahead, including new trim wheels (with animated handles) and other fine details.

As always, the screenshots are work-in-progress and do not represent the final product.
