Quad Line kites that have moved on
Revolution EXP[Retired] : The Revolution kite. The entry level Revolution and was my first quad line kite (May 2001). This original kite has long since been retired (although the spars are still in use in one of my custom Revolutions).
Revolution 1.5 SUL[Retired] : The low wind (files from zero mph) version of the Revolution (February 2002). The leading edge spars and handles are still in use with the current Revolutions..
Lidl Quad[Sold] : A very cheap quad from the Lidl Supermarket (July 2008). This never flew especially well for me and was sold a number of years back.
Airbra (Custom) [Retired] : The Airbra, my homemade version of the Benson Airbow (January 2004). It never worked quite as well as the official version.
