The TKT Trainer can help you practice your True Kick Terminology and improve your understanding of vert kicking. Select your starting stance, takeoff, in-air spin, and kick to form a descriptive sentence of the trick. Use the explanation link to step your way through a breakdown of the TKT name for that trick. See the TKT Reference for full documentation of True Kick Terminology.
The Invert Rotation Calculator can help you become familiar with Invert categories and understand their rotation. Select your starting stance, base rotation, and landing to form a descriptive sentence of the trick. Use the explanation link to step your way through a breakdown of the skill and its rotation.
Note: currently there is only a horizontal/inverted demo for flatspin at complete landing per stance.
