● 4 x HQ 2.9 x 2.9 x 4 3" Propeller
Aerodynamic 4-Blade Design for Aggressive Control
Precision-engineered blade curvature maximizes thrust-to-weight ratio during high-G maneuvers. The balanced lift distribution locks in attitude during dives and rapid yaw spins, giving competitive pilots 23% sharper cornering response than standard triblades. Fly harder without sacrificing stability.
Military-Grade Nylon Fiber Composite
Injection-molded with aerospace-certified 30% glass fiber reinforced nylon. Survives 80mph concrete crashes with only edge deformation, not shattering. UV-resistant formula prevents brittleness after 200+ sun exposure hours. Your toughest crash kit companion.
Laser-Balanced Harmonic Suppression
0.01g micro-tolerance dynamic balancing eliminates high-RPM resonances. Reduces motor temps by 14°C at 28,000rpm and cuts "jello effect" in HD footage by 80%. Compatible with 6S LiPo ultra-high KV builds (up to 45,000rpm).
Plug-n-Play Cross-Platform Compatibility
Fits 90% of 5" freestyle/racing frames with universal 5mm shaft holes (Gemfan/Emax standard). Pre-threaded brass inserts accept M5 screws without splitting hubs. No re-tuning needed - optimized for Betaflight defaults.
Weight-Optimized Performance Sweet Spot
5.2g per blade achieves perfect rigidity-to-mass ratio. Delivers 12% longer flight times vs. carbon hybrids while maintaining cinematic glide inertia. The "Goldilocks zone" for freestyle flow sessions.
