Throw ring frisbee like wing thing

These are all frisbee like throw rings with a generic wing shape, they seem to fly pretty stable.

Throw these rings upside down except the "reverse" one which has the wing in the other direction for optimal flight stability.
Be careful with the reverse one, it has a fairly sharp outer edge and is only intended for educational purposes.
