A major advantage of the flex-wing (principally the Rogallo type) is its simplicity in having no separate tail surfaces. Nonetheless, innovators over the years have attempted to combine the flex-wing’s simplicity with additional tail surfaces to achieve greater performance.


  • Project Quicksilver in Hang gliding before 1973 part 2. Although not strictly a flex-wing in that any change in geometry of the wing in flight had no direct bearing on its flying characteristics, the Quicksilver was built using contemporary flex-wing hang glider technology.
  • Tweetie in Hang gliding 1974 part 1
  • CGS Falcon in Elberta Dune, Michigan, July 1974
  • Luff in the time of cholera for the simplest of all tails; the sailfeather
  • Scientific American hang glider, the Markowski Eagle III of 1974. The way the sail of the Eagle III changed shape and the effect of that change were unique.
  • Miles Wings Gulp in Hang gliding 1975 part 2
  • Canards in Skyhook Sailwings, the early British manufacturer. Like one of Bob Lovejoy’s early Quicksilver prototypes, Len Gabriels’ 1977 Skyhook experimental glider had the ‘tail’ in front…
