XR Fleet Overview
The XR5 Vanguard, DeltaGlider-XR1, and XR2 Ravenstar are cutting-edge, high-performance spacecraft for the Orbiter Space Flight Simulator.
All XR vessels are built on a common framework and share similar internal systems. Highlights include three (XR1), four (XR2), or five (XR5) 2D instrument panels that natively support 1280-, 1600-, and 1920-pixel-wide resolutions, high-performance Altea Aerospace SCRAM engines, complex damage simulation, custom sound effects, over 250 voice callouts performed by actress Sally Beaumont, and highly precise autopilots just to name a few. In addition, the XR2 and XR5 include a payload bay with full payload support via a custom panel. The XR codebase consists of over 60,000 lines of C++ code.
The XR1's 3D mesh is based on the DG-S mesh included with Orbiter, while the XR5 and XR2 use all-new 3D models created from the ground up by Russell Hicks and Steve "Coolhand" Tyler, respectively. Check out more of Steve's 3D models at Coolhand Graphics. The XR5's skin and textures were created by PennyBlack.
XR vessels are designed to be pilots' ships, and with all the realism settings set to maximum the ships are significantly more challenging to fly efficiently (and safely) than Orbiter's default DeltaGlider; i.e., pilot workload is higher. However, each vessel is fully configurable via its configuration file, and with all the realism settings disabled each vessel is just as forgiving to fly as the default DeltaGlider. The configuration file also features a custom [cheatcodes] section that allows the user to directly set certain ship's values such as maximum engine thrust, fuel capacity, ship mass, etc.
