Huge Size & Pitch: These are 13″ diameter, 12″ pitch, 3‑blade props, designed for very large “X‑class” or heavy-lift builds.
Strong Material: Made of carbon-reinforced nylon (sometimes described as glass‑fiber reinforced), which offers excellent stiffness and durability under high load
Good Mass & Thrust: Each prop weighs about 49.8 g, which is heavy but reasonable for this size — allows strong thrust for big motors / big quads.
Balanced Rotation: The pack includes 1 CCW + 1 CW prop, so it’s ready to be used in a balanced way on a 2‑motor or as part of a larger setup.
High‑Performance Use Case: Ideal for X‑class racing, long‑range quads, or builds that need high thrust with large props.
