For a highly detailed, heavy scale model like the YuXiang F09-S Coast Guard UH60, maintaining perfectly tracking airfoils is essential for the onboard GPS auto-hover and FPV camera stabilization systems to work correctly. If your helicopter experiences a hard landing, clips low branches, or tips over on the pad, the spinning blades will easily chip, crack, or suffer stress fractures. Flying with warped or dented rotors creates intense, destructive high-frequency vibrations that blur your FPV feed, confuse the autopilot sensors, and can cause sudden in-flight tracking failure. Replacing your compromised airfoils with this factory-original 4-piece main blade set instantly restores smooth aerodynamic efficiency, whisper-quiet tracking, and rock-solid flight stability.  \u003cstrong\u003eShips worldwide.\u003c\/strong\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"12,0,0\"\u003e\u003cb data-path-to-node=\"12,0,0\" data-index-in-node=\"0\"\u003ePrecisely Molded 4-Piece Scale Set:\u003c\/b\u003e Engineered custom to match the four-blade rotor head configuration of the 1:19 scale Coast Guard UH60 fuselage layout.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"12,1,0\"\u003e\u003cb data-path-to-node=\"12,1,0\" data-index-in-node=\"0\"\u003eAerodynamic Swept-Back Winglet Tips:\u003c\/b\u003e Designed with curved trailing edges as shown to optimize lift coefficients while significantly lowering vortex noise and drag.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"12,2,0\"\u003e\u003cb data-path-to-node=\"12,2,0\" data-index-in-node=\"0\"\u003eFactory Dynamic Weight Matching:\u003c\/b\u003e Pre-balanced out of the box to guarantee perfectly identical aerodynamic loads across all four corners, saving you tedious setup time.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"12,3,0\"\u003e\u003cb data-path-to-node=\"12,3,0\" data-index-in-node=\"0\"\u003eHigh-Contrast Warning Lines \u0026amp;
