I just wanted to emphasize the fact that the OP's terminology was correct and that these are considered flywheels in this application.

But they're not, these wheels are not storing energy (or at least enough energy to make any difference) which is the exact point of a flywheel.

That's a flywheel!

Yes they are. They're storing kinetic energy. If the wheel needs to be spun up before the ball contacts it for it to work as intended, then the wheel is a flywheel. Whether or not it is a particularly good flywheel isn't relevant. Spinning wheel shooters in FRC work by storing kinetic energy, which is exactly what a flywheel is.

It is still a flywheel, just not a particularly good one.

It's definitely a fly wheel but not in the traditional sense. We spin the wheels up for a couple of seconds to gain energy before the ball is pushed into the wheel therefore it is a fly wheel.

looks nice but what whats your method of loading it?

You guys might need some sleep. I can't see those wheels producing a useful amount of lift at all.

They do.

It's just a matter of reversing the motors and pitching it down.

Do you have pictures or anything to support this? I'd be interested in seeing what kind of damage of they caused, and what the application was that caused it.

We did some prototyping with those wheels, and while they did scuff the ball, they didn't cause any major damage to our ball. It likely depends on the amount of compression you have.

We had the same result in the process of testing, but we got it to a point where there was no sign that it was fired.

What motors are you using there in the image?
