Analysis of information sources in references of the Wikipedia article "Sport kite" in English language version.
Dual-line kites have been around for a surprisingly long time. Possibly the first recorded two-liner was made and flown by a Swiss man, Dr. Colladon, in the mid 1800s.
I can think of two ways of looking at old school / new school, and one indeed is the standoff, the development of and implementation of the standoff, is where slackline tricking started, is where new school started, everything before being old school. My personal understanding of it and my timeline of things is around 2000-2001 when this whole new generation of multi-axis, multi-combo type tricks were introduced to the scene both in Europe as well as in the states.
By pulling and releasing the single line with subtle control and precise timing, the flyer can maneuver the kite in truly amazing ways -- but it isn't at will because the flyer has to wait for the exactly-right instant each time. Thus fighter kites are not stunt kites.
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.
