DESIGNED FOR FREESTYLE

Smoother line, sharper response

Engineered in collaboration with Black Bird FPV, the unique 4.9" diameter combined with a 3.9" pitch delivers an incredibly linear throttle curve. Experience ultimate precision and immediate recovery during aggressive snaps and technical maneuvers.

AERODYNAMIC OPTIMIZATION

High-KV motor synergy

Weighing just 3.7g, the lightweight profile reduces rotational inertia and motor burden. An updated polymer design minimizes blade flutter and drag, allowing the BB4939 to maintain maximum traction during hard cornering and violent punch-outs.

BUILT TO LAST

Polymer durability

Molded from high-grade Polycarbonate (PC), these propellers are engineered to absorb heavy impacts without snapping. The optimized structural stiffness reduces bending under extreme load while ensuring you can bend them back and keep flying after a crash.
