Introducing crosspoints

Crosspoints are drilled as a control exercise for poi flight paths. You spin and deliberately make the poi cross through a consistent “X marks the spot”, using a chosen visual target to check accuracy and timing as the heads pass through the same point each cycle.

This trains stabilisation of the pattern in 3D space, supporting cleaner plane control and more readable geometry. You also explore shaping the cross by tightening it near the arm or widening it side-to-side, refining how hand travel affects the X without simply making the pattern bigger.
