As of 2010, the Rocket Racing League is utilizing a highly modified Velocity XL fixed-gear airframe and an Armadillo Aerospace 2,500 pound thrust liquid oxygen (LOX) and ethanol rocket engine in both its Mark-II X-Racer and Mark-III X-Racer demonstration vehicles. The Mark-II and Mark-III racers can liftoff into the air in just 4 seconds after the rocket engine is ignited; both vehicles are limited to a top flight speed of 300 mph (480 km/h). The rocket engine is a LOX-Ethanol, film-cooled, pressure-fed, blow-down design with a 10 to 15-foot (4.6 m)-long exhaust plume. Plume-seeding technology allows the plume color to vary from red to green to yellow to better facilitate race spectators in keeping track of specific racers while in the air.
The Mark-II (N205MB) racer utilizes a standard fixed-gear XL airframe, modified for the addition of the Armadillo rocket propulsion. The Mark-III (N133XP) airframe was modified during manufacturing at Velocity Aircraft explicitly for use as a rocket racer, with canopy top, center seat and control stick, and other enhancements.
