A toy for launching ring airfoils comprises a member (58), a ring airfoil support (60) mounted on the member, and a propelling element (62) for moving the support along the member from a first to a secon d position. The ring airfoil moves with the ring airfoil support as the ring airfoil support moves as the support decelerates at the second position, the ring airfoil is launched forward. The member may include a helical channel (68) which receives a pin (78) attached to the support to impart spin to the support and ring airfoil. The toy may include a protective housing (32), a return element (34) to move the support to a launch-ready position, and a trigger (106) to release the support for forward movement. Components of the toy are designed so that the characteristics of the ring airfoil are within certain safety limitations.
