Apparatuses for controlling payload descent are described herein. For example, in one embodiment, a puck is provided that includes a top planar surface, a bottom planar surface opposite the top planar surface and an inner peripheral surface that is substantially perpendicular to the top planar surface and the bottom planar surface. The inner peripheral surface, the top planar surface and the bottom planar surface define a centrally located bore that is substantially perpendicular to the top planar surface and the bottom planar surface. Puck teeth are located on the inner peripheral surface. An outer peripheral surface bounds the top planar surface and the bottom planar surface. An exit port surface is substantially perpendicular to the top planar surface and the bottom planar surface. The exit port surface is between the inner peripheral surface and the outer peripheral surface and couples the top planar surface to the bottom planar surface.
