What MasterAirscrew - Windsor Propeller does

Master Airscrew (operating as Windsor Propeller) is a California-based propeller manufacturer founded in 1978 by Fred Jamieson, specializing in precision-engineered propellers for model aircraft, FPV and racing drones, and consumer camera drones (notably the full DJI lineup, plus Hubsan, GoPro Karma, 3DR Solo, and Autel platforms). The company's core technology combines 45+ years of aerodynamic design expertise with proprietary materials and processes, including glass fiber reinforced nylon composite (introduced 1980), carbon fiber reinforced composites, scimitar-shaped blade geometry for low-noise/STEALTH operation, and factory balancing for vibration reduction. The product portfolio spans more than a dozen specialized series (3-Blade, GF, K, EO, Classic, Scimitar, Formula One, Wood, MR, 3MR, X Power, BN Bullnose, RS Racing) priced $5.32–$65.98 per unit, plus accessories, building tools, branded apparel, and a custom propeller design service for industrial, military, and scientific buyers.

The company operates a direct-to-consumer e-commerce model through a Shopify storefront with global shipping (USPS, UPS, DHL), free US shipping over $40, and content marketing via an Academy and News/Blog. Revenue is generated entirely from one-time hardware sales with no subscription or recurring contract structure. Customer segments are intentionally diversified across model aircraft hobbyists, DJI drone camera operators, FPV racing/freestyle/long-range pilots, cinelifter operators, and commercial/industrial/military/scientific buyers — with a cumulative customer base described as hundreds of thousands. The business is privately held with no disclosed funding rounds, parent company, or institutional investors, and is currently led by co-founder/CEO Boris Iskrev.
