The DeltaGlider-XR1 (more commonly known as just "the XR1") is a new high-performance spacecraft for Orbiter that is a sophisticated rewrite of the DG-S mk-IV included with the Orbiter 2006 P1 release. Highlights include all-new instrument panels that support 1280-, 1600-, and 1920-pixel-wide video modes, high-performance SCRAM engines, complex damage simulation, a virtual cockpit, numerous voice callouts, and new highly precise autopilots just to name a few.

The XR1 was designed to be a pilot's ship, and with all the realism settings set to maximum the ship is significantly more challenging to fly efficiently (and safely) than the default DeltaGlider; i.e., pilot workload is higher. However, the XR1 is fully configurable via the Config\DeltaGliderXR1Prefs.cfg file, and with all the realism settings disabled the XR1 is just as easy 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.
