| Sleds and foils are nearly unbreakable and are either completely soft (frameless) or have the minimum of spars incorporated into their design. All are wind inflated and require little or no assembly. Larger sleds and foils are very stable and generate tremendous pull, even in the lightest of winds. These are often used for kite aerial photography due to the stability and lifting potential |
| A box kite is a high-performance kite, noted for developing relatively high lift. It was invented by the Australian Lawrence Hargrave in 1893 Hargrave also linked several box kites together and successufully lifted men 16 ft off the ground |
