The Guillow Delta Dart is a small one-piece glider molded of EPS foam plastic. These light-weight gliders can be launched with a rubber-band or hand-tossed.
We've also used the Delta Darts as "parasite gliders" for model rockets. Glue a small piece of a dowel under the nose of the glider. The dowel hooks into a small section of a launch lug glued above and centered between a pair of fins on the rocket. During the flight, the glider hangs on the small launch lug, At apogee, the parasite glider separates and glides down while the rest of the rocket comes down under its parachute.
This is a package of two (2) foam gliders.
