Seriously, don't forget to take into account that these wheels are running at speeds they were NOT designed for. Make sure anything you attach to them can handle the speeds.
I think if the weights will work on sport bikes that they will be fine on a robot wheel a 2006 yzf r6 has a top engine rpm of around 21,000RPM. The sixth gear reduction ratio is 1.074. Dividing 21,000RPM/1.074 will produce the RPM of the rear wheel. This comes out to be 19,553RPM. I don't think the shooter wheel is hitting that speed lol Now i realize you may do the math and realize nobody ever drives that fast but when the bike is doing 250MPH, people do drive that fast on the track, the rear wheel is spinning at abut 3,703RPM which is faster then any shooter wheel is spinning. So Andrew you are just fine using wheel weights

3703 < 5000 So I'm not seeing your point. I know one of my wheels is geared close to 7500 rpm. Now, I'm aware I'm not hitting that speed but I'd be willing to bet you that it's well above 3700rpm. And frankly, I don't care if it "should" be safe. I care that it is. I care that teams took some time to put in safe guards to prevent shrapnel hitting people because I'm selfish and I enjoy the use of all of my limbs.

That's well over 1200 miles per hour. I don't think the wheel itself would survive, much less stick-on weights.

Based on reports I've seen here, some frisbee shooters are spinning their wheels at 6000 RPM or higher. 5000 RPM seems common. Whether or not you use wheel weights, if you're running a wheel at several thousand RPM, you'd better have an effective containment system to protect the outside world in case something spontaneously disassembles itself.

I believe those are the smaller wheels, not the pneumatic. If someone is spinning that pneumatic wheel over 4,000 RPM then the are lucky they still have a wheel.
