Flex-wings with tails
This related topics menu links to material in the main hang gliding pages. The links here are in chronological order.
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. 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.
