Xtreme Prototypes X-1 SG

Aircraft

X-1A

• 'Bell-USAF' orange version
• 'Bell-USAF' aluminium version
• 'Bell-USAF-NACA' white version

X-1B

• 'Bell-USAF-NACA' aluminium version

X-1C (never actually built)

• 'USAF' aluminium version with front machine gun, yaw-damping surfaces on wing and retractable ventral fin

X-1D

• 'Bell-USAF' aluminium roll-out version

B-29 'Superfortress'

• One light variation of a B-29 carrier aircraft on specially equipped X-1A and X-1D models (exterior model only, visible when the X-1 is airborne). The aircraft features animated propellers and control surfaces (see description above)

Virtual Cockpits

• Three highly detailed and fully functional virtual cockpits (X-1A/D, X-1B and X-1C) with over 200 3D animated gauges, switches, levers, light indicators and flight instruments with 'tooltips'
• Fully functional instrument panels with custom X-1 rocket aircraft systems
• Centre pedestal (switch) panel
• Detailed seat, side controls, levers, pedals, oxygen regulator, hoses and pipes, and other cockpit items
• Modified (fictitious) ARC-5 radio for use with civilian frequencies in Flight Simulator X. The set has two VHF communication transceivers (COM1 and COM2), an automatic direction finder (ADF) and a radio-navigation receiver (VOR) to allow for a fictitious journey around the world in your X-1 at speeds beyond Mach 2
• Navigation instruments (fictitious, optional)
• Cockpit lighting - this optional feature is fictitious, but will allow you to fly the X-1 SG even at night
• Sperry A-12 Propilot (X-1C)
• Gunsight (X-1C)

Custom X-1 rocket aircraft systems

The following rocket aircraft systems are simulated as closely as possible within the limitations of Flight Simulator:

• XLR-11 power plant system and control
• Turbine-driven propellant pump and control
• Fuel system
• LOX system
• Hydrogen peroxide system
• Nitrogen system
• Electrical system (with DC-AC conversion)
• Fire detection/extinguisher system
• Custom rocket aircraft instruments, controls and gauges, including dome loading pressure regulators and spill valves
• Emergency jettison system
• Pilot's oxygen system
• Cabin pressurisation system

Flight model

• One Reaction Motors XLR-11-RM-5, 5900-pound four-chambered liquid-fuel turbo-rocket engine, capable of delivering more than 5,900 pounds of thrust
• High-altitude flight above 90,000 feet
• Supersonic flight up to Mach 2.5
• Ground take-off or high-altitude launch
• Good manoeuvrability at supersonic speeds
• Excellent gliding capabilities

Aircraft models 

• More than 40 animations
• Reflective high-resolution textures with bump maps
• Night textures
• Historical markings and liveries on each aircraft
• Animated control surfaces: X-1 all-moving tail (elevator trim), elevator, ailerons with trim tab, flaps, Vertical stabilizer/rudder with trim tab, Retractable ventral fin (X-1C), Yaw-damping surfaces on wings (X-1C)
• Detailed steerable front gear
• Detailed main landing gear
• Movable glass canopy (with jettison animation)
• Cockpit details include pilot and animated sticks, levers and parts
• Functioning nose-mounted .50 cal. machine gun (X-1C)
• Antennas, pitot tube and research probes
• Rear propellant jettison tubes and engine turbopump exhaust pipe
• XLR-11 rocket engine combustion chambers (4)

Special effects

Special visual effects, some with sound, include:

• Rocket engine ignition, combustion flames and shockwave effects
• Rocket engine smoke and contrail effects
• Igniter test effects
• Propellant jettison effects (fuel, LOX and H2O2)
• Engine turbopump exhaust effect
• N2/LOX bleed effect
• Condensation and vapour effect around the cold LOX tank when filled
• Wing vortices and vapour trails
• Machine gun effect (X-1C)
• B-29 contrail effect

Miscellaneous 

• Automatic ignition sequence (optional)
• Custom sound set
• Camera definitions (external and internal)
• Fictitious saved flights inspired by real X-1 SG test flights
• X-1 SG aircraft kneeboard reference tab and check list (from within FSX)
• Comprehensive 75-page PDF user manual (English & French) inspired by the original Bell X-1A Pilot's Handbook

"The virtual cockpit of the X-1 is meticulously rendered and the crispness and smoothness of the gauges are excellent... the sound suite of the xtreme Prototypes is superb... the systems modelling in the X-1 is fantastic... The multitude of visual effects is admirable... Detailing of both the virtual cockpit and external models are exquisite... The preset external camera views are some of the best I've ever seen for an add-on... An exciting and well-rounded add-on that is a challenge to fly" PC Pilot (90%, Classic Product Award)

"A good quality simulation of the ell X-1 aircraft complete with a relatively complex cockpit environment along with a highly detailed (almost museum piece) external model of the X-1 family... Externally the X-1 aircraft are eautifully rendered to incorporate all of the current FSX-enabled features... Does not disappoint in the sound department" Computer Pilot
