The GA200L-STOL’s highly tapered, swept blade planform and proprietary airfoil is designed for optimized blade loading distribution resulting in maximum efficiency and minimum noise. The idealized blade shape is only made possible with modern advanced carbon composite structures developed in-house by WhirlWind Propellers. All WhirlWind propellers come standard with electroformed Nickel leading edge shields for superior fit and abrasion protection and Polyurethane top coat. The hub is CNC machined from aerospace aluminum and is dimensionally certified. The GA200L-STOL blade design is optimized for maximum efficiency and minimum noise. The blade structure is manufactured from thermoset epoxy/graphite composite matrix. This advanced composite structure ensures high strength and blade accuracy in all flight environments. Only WhirlWind propellers come standard with electroformed Nickel leading edge shields for superior fit and abrasion protection. The hub is CNC machined from aerospace aluminum and is dimensionally certified. The WhirlWind GA propeller series are ground pitch adjustable aircraft propellers featuring advanced aerodynamic and composite design. The satin black surface finish shows off the quality craftsmanship and attention to detail.
