FlyingIron Simulations Updates Spitfire with New Sounds and More

More than two years after the products initial release, FlyingIron Simulations’ mighty Spitfire is still getting major updates and changes. The latest update, 1.4.0, which is available right now from FlyingIron Simulations and soon on the Marketplace, continues the trend with an entirely new sound set and changes to the flight model to make the plane even more authentic. Some of the bugs and issues from previous versions have been fixed, or changed based on user feedback.

Most notably, the team has worked together with the RAF’s Battle of Britain Memorial Flight team to fine-tune their flight dynamics and simulation model. This has resulted in a more authentic flight envelope with refined flight model, engine and ground handling.

The update also contains other improvements, such as authentic differential braking (using the brake lever and rudder), new cockpit lighting and a major sound overhaul. Some previews of the sound overhaul can be found below, though more tweaks have been made since the video was made so it does not represent the final product entirely.
