From their announcement:
Set of 5 flight stands. The Large flight stands are designed with an arrow shaped base to easily know which direction the asteroids are moving. The larger base is perfect for use with Lava Rock, and available from most outdoors and hardware retailers. The flight stands are compatible with all of our peg accessories such as the numbered dials and dice trays for even more detailed tracking of the asteroid movements.
These stands require assembly with glue. Litko recommends our Craftics #33 acrylic cement for all of our acrylic plastic kits.
