For the YuXiang F112S 32:1 scale AH-1 Cobra, a perfectly true main shaft is vital to transfer brushless motor power smoothly to the rotor head. This replacement main shaft set solves the problem of power transmission loss and electronic stabilization glitches caused by a warped spindle, ensuring rock-solid flight stability.  \u003cstrong\u003eShips worldwide.\u003c\/strong\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2 data-path-to-node=\"8\"\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,0,0\"\u003e\u003cb data-path-to-node=\"11,0,0\" data-index-in-node=\"0\"\u003ePremium Tempered Steel Shaft:\u003c\/b\u003e Engineered from wear-resistant, high-strength stainless steel to handle high rotational torque and resist bending during hard impact.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,1,0\"\u003e\u003cb data-path-to-node=\"11,1,0\" data-index-in-node=\"0\"\u003eFlawless Machining \u0026amp;
