Regards,
Centrifugal force (or centripetal depending on your point view) Depends on tangential velocity not RPM. Motorcycles & cars see easily 50 m/s which is more than our wheel, at least, is spinning.

All the wheels I have seen use on the Frisbee shooters are being used "off label" from what the manufacturer intended. Liability laws being what they are, I doubt you will get buy in from them if you asked.

So it is incumbent on us to make sure our robots are safe. This very much includes making sure they are no loose bits on the wheel that can fly off and hurt some one. Also that you are not spinning the wheel at a speed that will make it come apart.
Also checking the shooter wheel should be part of everybody's pit check list before every match.
