A Classic Addon Available for Download for a Limited Time
Over the years, some of our products have become legacy due to the constant evolution of the simulation platforms or because they are being replaced by better, up-to-date products with much more features. By popular demand and for a limited time, we are now please to offer these products a very special price.
Please note that the XP X-1 SG v1.0 addon is now a legacy product for which we can no longer offer technical support. It is offered to collectors as is.
The Second Generation of the X-1 Rocket Plane
The Bell X-1 SG was an advanced version of the original X-1, the first aircraft in history to have broken the sound barrier. The second generation of X-1s, built in the late 1940s and early 1950s, were designed to double the speed of sound and set new altitude records in excess of 90,000 feet.
The new X-1s were similar to the original (orange) aircraft but were about five feet longer, 2500 pounds heavier and had a conventional glass canopy. The new airplanes also had a more advanced version of the XLR-11 four-chambered liquid-fuel turborocket engine.
The Xtreme Prototypes X-1 SG v1 addon contains six variations of the four Bell X-1 Second Generation rocket planes (X-1A/B/C/D). Each exterior model is fully detailed with over 500 parts and 40 animations. The three fully functional virtual cockpits contain over 800 parts and more than 200 animated full-3D gauges, switches, levers, light indicators and flight instruments. A custom X-1 flight model was designed to simulate rocket-powered high speed and high altitude flight in the simulator. All rocket aircraft systems present in the real X-1 SG are simulated.
This addon will allow you to fly at very high altitudes at more than twice the speed of sound, simulate virtually every procedure required during an X-1 research mission (including emergency procedures such as extinguishing an engine fire or jettisoning the canopy to bail out), and even test the never-built X-1C that was to be equipped with the Sperry A-12 Propilot system and a .50 caliber Browning machine gun in the nose to test high-speed armaments.
As a bonus, we have included a light version of a modified B-29 Superfortress carrier aircraft to simulate high altitude launches over the Mojave Desert in the specially-equipped X-1A and X-1D models. Taxiing and taking off from the ground is also possible, as attempted once with the original X-1 in January 1949 (the only time a rocket-powered research aircraft took off conventionally). An unlimited fuel mode and an automatic ignition sequence button are provided, as well as optional radio navigation instruments to allow for (fictitious) long-duration flights and travelling around the world at beyond Mach 2 in the simulator.
For the serious flight simulation enthusiast and X-1 fan, the Xtreme Prototypes X-1 Second Generation v1 addon is a chance to relive important moments of the history of flight and experience the performance of a series of aircraft whose new rocket systems, cockpit ergonomics and flight controls were quite a challenge for the test pilots who flew them more than seventy years ago.
