To answer a few questions

The shooter was about waist high, so 3 or 4 ish feet off the ground and it was angled up with just a 2x4 under the front

The wheel is direct driven by the CIM and just directly hooked to a battery. I believe this leads to around 4000 RPM

At first we cut the wood circle and placed it exactly 11 inches away from the wheel
Then we added two polycarbonate sheets, each 1/8 in thick to the inside of the curve. So we ended up with only about 1/4 in of compression

We were wondering how changes in RPM vs compression would change the trajectory and we found that using a half dead battery, so a lower RPM, the frisbee only flew marginally less distance and was stills table. However, removing just one 1/8 in sheet of polycarbonate caused the frisbee's range to drop from 50 to about 10 feet.

We will be trying a higher angle soon, however based on other videos, including the Robot in 3 Days robot, shooting at a higher angle will still work
