Looks good, nice and clean... those wheels though... they look like they might rip the ball up.

Are the Flywheels actually mounted that high? We've found that mounting them in the exact center works best.

Looks like a nice simple way to score. Easy to build. Doesn't take up too much space. Looks easy enough to tweek and make a consistent shot out of it.

Nice job

A flywheel does not have to be heavy, to be able to store energy/momentum. The speed of rotation is also important as well.

Just look at Formula 1 Racing Flywheel System. They use 240 mm diameter flywheel which weighs 5 kg and spins at around 64,500 rpm. They can store enough energy to give a power boost of 60 kW for 6.67 seconds.

a heavy revolving wheel in a machine that is used to increase the machine's momentum and thereby provide greater stability or a reserve of available power during interruptions in the delivery of power to the machine.

I can see both sides of this argument. In general when I think of a flywheel I think of something that stores energy and/or dampens. Personally I would not consider a shooter wheel a flywheel but I have no problem with those who choose to do so.

At least it's not a piston

Yeah, I was attempting to indirectly point out that you can't say a wheel is, or isn't, a flywheel based on its weight. Because whether or not it's "heavy" just depends on how much energy you need to store.

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

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.

Re: pic: FRC 2869 - 2016 Shooter

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.
