The original ToroSpin Turbo is a superb rotor launcher. This is a relatively simple modification of the original rotor to make it fly considerably higher, and to make it more robust than the original.

I took the original and truncated the blades at roughly half their original diameter, and then surrounded them with a circular ring. This ring adds both rigidity and also more mass to provide more momentum for spinning both faster and maintaining the higher rotational speed for longer.

No need for additional instructions, this rotor is used in exactly the same way as the original
