Quad line kites have been in use since at least 1899,<ref>{{cite web |url=https://airandspace.si.edu/exhibitions/wright-brothers/online/fly/1899/kite.cfm |title=1899 Wright Kite |author=<!--Not stated--> |website=Smithsonian National Air and Space Museum |access-date=June 23, 2022 |quote=To allow for wing-warping, they left the kite unbraced between the front and rear struts (vertical posts). It was controlled with four lines running from the top and bottom of the front outer struts to a pair of sticks held by the operator. Tilting the sticks in opposite directions caused the wing structure to twist. |archive-date=31 Oct 2022 |archive-url=https://web.archive.org/web/20221031152520/https://airandspace.si.edu/exhibitions/wright-brothers/online/fly/1899/kite.cfm }}</ref> documented in designs likely simultaneously invented by [[Wilbur Wright]], [[John Joseph Montgomery|John J. Montgomery]], and possibly other aviation pioneers for flight control by [[wing warping|warping the wing shape]] which featured as part of the [[Wright brothers patent war]]. Modern quad-line sport kites were re-popularized in 1988 with the creation of the "Neos Omega", later called the "Revolution 1". Both historic and modern quad-line kites allow the four lines to tension different areas of the sail body, resulting in both sail shape deformation and tension changes which in turn control the flight.

The modern quad line kites were popularized through 1989 being flown in the "innovative" competition category, and were quickly adopted by top fliers. Performances with the kites achieved top rankings at many competitions in 1989.<ref>{{cite web|url=http://www.revkites.com/history-revolution-kite|title=A Quick History of the Revolution Sport Kite - Revolution Kites |website=Revolution Kites}}</ref><ref>{{cite magazine |last1=Batdorff |first1=Cris |last2=Landes |first2=Keith |last3=Sedgwick |first3=Lee |date=Summer 1989 |url=https://kitelife.com/1989/06/01/skq-vol-1-no-4-summer-1989/ |title=Stunt Kite Quarterly |magazine=Stunt Kite Quarterly |pages=15–17, 18–20, 22–27, 33, 36–37, 42–43}}</ref> Quad-line kites further gained popularity after sport kite team The Flying Squad quad-line team won back to back STACK European championships<ref>{{cite web|url=http://www.theflyingsquad.org/|title=The Flying Squad - Kite Display Team|website=The Flying Squad}}</ref> and later Team iQuad receiving industry awards for promoting the sport globally between 2006-2012.<ref>{{cite web |url=http://www.teamiquad.com/about/ |title=Team iQuad - Stunt Kite Team - About |access-date=April 16, 2022}}</ref> Revolution Kites initially dominated the quad-line market thanks to patent protections, but competing brands proliferated after the patents expired.

Quad-line kites are noticeable by the way that they can hover in space unlike any other sport kite. These kites can be extremely precise, hover in orientation, fly in any direction including sideways and reverse, even land at a specific spot on a wingtip.
