We build cockpits, not paint shops. You will see that on the outside of these two.
The Project Magenta B737 and A320 are now packaged for Prepar3D v5 and v6. One add-on each, the same files for both versions: unzip it into the Prepar3D Add-ons folder in your Documents and it appears in the aircraft list. Nothing goes into the simulator itself.
They are made for rigs. Flight model, outside view and lights, and that is all – no panel, no gauges, no sound. The cockpit is yours: our glass cockpits, MCP, CDU, pmSystems and pmSounds, and your hardware. The landing and taxi lights were rebuilt and work in both versions.
About the liveries. The 737 got a magenta stripe and our name, the A320 just our name in pink on plain white. Painted in-house, and it shows. If you can do better, send it in – we would love to see it.
If you fly X-Plane 12, the same two have been on the site since September.
Both are on the update page, in Your Updates.
