Paul Kenny teaches us how to perform a MAC (Midair Attitude Correction). Note that in the video, we erroneously identify it as a SUB (Speeded Up Brush). What Paul is demonstrating is actually a MAC. Here’s a video on the SUB, and another video of Tom Leitner’s SUB throw.
A MAC is when a player touches the frisbee in flight to change the angle or direction of flight of a flying disc. It can be done by touching the disc on top, or on the outer rim (a brush), or the bottom of the rim (a cuff). Does a tip qualify as well? Chime in if you know.
The top touch MAC as Paul demonstrates is useful to cause a disc to airbounce as it passes by you, or to flatten it if it’s too steep.
To perform a top touch MAC, touch or hit the disc on top as it is in flight. Paul demonstrates hitting a disc as it flies by. Where to touch it depends on spin of the disc and the desired outcome. To bring the nose up, hit a clock disc at 3 o’clock and counter at 9 o’clock. To bring the nose down, hit counter at 3 o’clock and clock at 9 o’clock.
Also, note that using downward force will aid gravity in pulling the disc to the ground. So, care must be used as to when and how hard to use a top touch MAC. A top touch MAC makes the most sense when its use will cause the disc to airbounce into the wind. Otherwise thetop touch MAC will just push the disc to the ground. Of course, that may be a trick of its own…MAC it down fast and then kick tip it back up. Or MAC it down and cuff is up. Or…let you imagination run wild.
