context_page_description: Quicksilver is a line of single and two-place high wing, single-engine, ultralight aircraft that evolved from weight-shift hang gliders including Bob Lovejoy's High Tailer.
  The earliest powered version, the Quicksilver C, was created as a self-launching hang glider, designed to allow pilots who lived in the flatlands to be able to self-launch without a hill. The design later evolved into an ultralight aircraft for powered cross-country flying.
  The aircraft line has been in production since the late 1970s and remains in production in 2018 by Quicksilver Aircraft of Temecula, California.
context_section_description: Quicksilver C
  The C model was the earliest powered version and consisted of the Quicksilver hang glider, including the weight-shift sling seat, with a McCulloch MAC 101 powerplant of 12 hp (9 kW), a V-belt reduction drive and a 1.7 US gal (6 l) fuel tank. The rudder is deflected by movement of the sling seat to create a coordinated turn. The engine is mounted in pusher configuration at the trailing edge of the wing. There is no landing gear and the aircraft is foot-launched.
  Quicksilver E
  An evolution of the C design the E is a new design which incorporates tricycle landing gear, including a fixed, non-steerable nosewheel, but no brakes. Some E models have been flown on floats. The standard engine is a 20 hp (15 kW) Cuyuna 215R or a Yamaha go-cart engine. The E maintains the use of a weight-shift sling seat acting on the rudder, although it also acts on the elevator through a servo tab attached to the seat to boost weight-shift control authority.
  Quicksilver MX Sprint
  The Sprint is an evolution of the E model, with a fixed seat and three-axis controls and a steerable nosewheel. The Sprint features a cable-braced single surface wing and 2/3 span ailerons. The standard engine is the 40 hp (30 kW) Rotax 447 which gives a cruise speed of 50 mph (80 km/h).
  Quicksilver MX Sport
  The Sport is an evolution of the Sprint, with the addition of a double-surface wing. The standard engine is the 40 hp (30 kW) Rotax 447 which, combined with the double surface wing, gives a cruise speed of 53 mph (85 km/h).
  Quicksilver MX-2 Sprint
  The MX-2 Sprint is a two-seat in side-by-side configuration ultralight trainer that features a cable-braced single surface wing. The standard engine is the 50 hp (37 kW) Rotax 503 which gives a cruise speed of 51 mph (82 km/h). The Rotax 582 engine of 64 hp (48 kW) is optional.
  Quicksilver MXL-2 Sport
  The MXL-2 Sport is a two-seat in side-by-side configuration ultralight trainer that features a cable-braced double surface wing. The standard engine is the 50 hp (37 kW) Rotax 503 which, combined with the double surface wing, gives a cruise speed of 54 mph (87 km/h). The Rotax 582 engine of 64 hp (48 kW) is optional.
  Quicksilver Sport II
  The Sport II is a two-seat in side-by-side configuration ultralight trainer that features a strut-braced double surface wing. The standard engine is the 50 hp (37 kW) Rotax 503 which, combined with the double surface wing, gives a cruise speed of 54 mph (87 km/h). The Rotax 582 engine of 64 hp (48 kW) is optional.
  Quicksilver Sport 2S
  Updated and developed version of the Sport II with a wider tailboom, 68" propeller, increased gross weight and the Rotax 582 engine of 64 hp (48 kW) as standard.
  Quicksilver Sport 2SE
