I made a video this morning testing the hawk. There was 4-5 fliers, and some deviation. I was about to do a grouping test, but my motor pooped out. I need to figure out the cause of the deviation, but right now I think that it is because the nub is angled, it is able to rotate within the arm. I'll do groupings and test the flat nub tomorrow. The wall was ~200 ft away.
