Velocity XL
# Velocity XL

The Velocity XL (XL: Extra Large) is an American amateur-built aircraft, produced by Velocity, Inc. It is an enlarged version of their Velocity SE canard pusher design.

## Design and development

The Velocity XL is 12 in (310 mm) longer and has a 20 in (510 mm) greater span than the SE. The standard XL has a cruising range of 875 nautical miles (1,620 km; 1,007 mi) and a 75% power cruising speed of 185 knots (213 mph; 343 km/h) air speed.

The XL is available in both fixed gear (FG) and retractable gear (RG) form and can accommodate either three or four passengers plus a pilot. The five seat versions, the XL-5 and the TXL-RG-5, have a rear bench seat for three rather than the alternative separate pair of seats.

Engines available as kits from the manufacturer for all models are the Lycoming IO-360 of 180 to 200 hp (134 to 149 kW), Lycoming IO-540 of 260 to 300 hp (194 to 224 kW), Continental IO-550 of 310 to 350 hp (231 to 261 kW) and the Franklin 6A350C1 of 205 to 235 hp (153 to 175 kW). Builders may use these manufacturer kits or design their own engine installations using a variety of other engines of similar power output.

## Variants

## Rocket Racers

The now-defunct Rocket Racing League utilized a highly modified Velocity XL FG 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 utilized a standard fixed-gear Velocity XL airframe, modified for rocket propulsion. The Mark-III airframe was more extensively customized during manufacture, explicitly for rocket racing, with a canopy top, center seat and control stick and other enhancements, in addition to the rocket propulsion added to the Mark-II.
