The Ultra‑Prop II is the latest evolution of the trusted Ultra‑Prop line, originally launched in 1984 with over 18,000 units in service. Designed for ultralights, hovercraft, airbo ats, and similar applications, it delivers high durability, aerodynamic efficiency, and precise engineering.Key Features Superior Materials & ManufacturingEach blade is made from carbon-fiber-reinforced thermoplastic and precisely injection-molded to stay within a tight 6‑gram weight tolerance. This consistency means you can replace blades without balancing or matching them. Aerodynamically Advanced DesignThe longer blades use an optimized airfoil, improved twist, and efficient planform design. The result is smoother airflow and improved overall performance. Higher Power CapabilityAvailable in sizes up to 66", the Ultra‑Prop II handles power levels over 100-HP—far beyond the limitations of earlier Ultra‑Prop models. Tested to LSA StandardsThe hub, pitch blocks, and blade retention system have been tested to meet Light Sport Aircraft standards for overspeed and load. Built for strength and reliability. High Value, Competitive PriceOffers composite-level performance for less than many wood props on the market. An optional spinner kit is also available to improve both appearance and performance. Why Choose Ultra‑Prop II? Lightweight and durable composite blades Easy blade replacement—no rebalancing required Designed for high‑power engines and larger aircraft Rigorously tested to industry standards Better performance at a lower cost Show more
