Well, we didn't go 25 feet. That's just a
bit further than you need, per G23 and page 4 of the field assembly drawings. We ran a test of our shooter on Saturday that can be seen here:

That's a CIM powering 4" compliant wheels at a 1:1 ratio, no where near full speed. You can see the robot next to it that was driving the shooter... our first trial we just plugged the motor into a battery through a modified drill handle (that lets us go forward and reverse, start and stop), and we actually hit the ductwork along the ceiling of our shop (approx. 18 ft high), so I have no idea how high it would actually go.
Obviously, there's still a bunch of fine tuning that needs to happen - mounting it to the robot to get the correct release height, figuring out the optimal release angle, optimal wheel speed for the distance shot we want to make, getting encoders on there to regulate the shooter speed, etc. But it was an exciting test!
I strongly recommend seeing what happens with your shooter when you feed balls in as quickly as possible. Our test sent balls through at about 5/sec, hopefully we can do better than that with an active feeder.
