Re: Curved Shooter help

Info on our curved shooter:

https://www.youtube.com/watch?v=S5gVpo6PZh4

Check out 1:08

90 Degree wrap
8" 40A durometer rubber wheel
CIM motor direct drive running at ~2000 (normal shot) to 3000 RPM(full court)

We use very light compression and the reason is that when you compress the frisbee, it will bend which causes it to track vertically on the curved wall of the shooter. This can result in extra friction or a curving shot. Using a softer durometer wheel provides a lot of traction which permits significantly less compression.

Also, if you are shooting at full speed and you start to see a purple halo on your wheel, this will make you shooter almost nonfunctional. This happens
when you are spinning your wheel too fast and it is melting the frisbee upon initial contact. You have to grind the halo off as soon as it starts to appear. Once it gets fairly thick, its almost impossible to remove.

Hope this helps.
