Yea, I built a linear belt shooter, but the problem we have so far is that the belts we use are to thin and tend to shift up and down, due to this we experienced many a failures. Amidst my failures though I did find a fix for the issue of the frisbee slipping and not getting a proper grip, just stuck a strip of pool noddle on the wall. Still would like to test this with a wider, grippier belt.
