A compromised rotor head hub introduces violent head-shake vibrations, ruins cyclic responsiveness, and severely degrades the performance of the optical flow and GPS flight stabilization system. Flying with worn or deformed rubber dampers also causes tracking issues and unwanted pitch oscillations. Finding matched high-precision head hubs with correct dampening hardness can be challenging. This official \u003cb\u003eYuXiang F112S Rotor Head Set\u003c\/b\u003e completely resolves rotor assembly slop and vibration. Precision-crafted to original factory tolerances, this set includes a rigid alloy rotor head hub and dual elastomer dampers to ensure ultra-smooth rotor blade tracking and factory-level 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\u003e\u003cb\u003eDurable Alloy Main Rotor Hub:\u003c\/b\u003e Engineered to handle high rotational torque and blade centrifugal forces without flexing or warping.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eHigh-Flexibility Rubber Dampening Rings:\u003c\/b\u003e Includes 2x specialized feathering shaft rubber dampers designed to absorb rotor disk vibrations and smooth out pitch transitions.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eExact Factory Geometry:\u003c\/b\u003e CNC-machined specifications guarantee proper spindle shaft alignment and linkage geometry for the 32:1 scale AH-1 Cobra head system.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eEssential Maintenance \u0026amp; Repair Kit:\u003c\/b\u003e Contains 1x Rotor Head Hub and 2x Feathering Shaft Rubber Dampers for a complete rotor hub overhaul.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eFor the \u003cstrong\u003eYuXiang F112S 9CH GPS RC Helicopter\u003c\/strong\u003e \u003cspan style=\"font-size: 0.875rem;\"\u003eonly.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eFull model page (specs \u0026amp; photos):\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.kidstoylover.com\/en-us\/products\/yuxiang-f112s-9ch-gps-rc-helicopter-32-1-scale-ah-1-cobra-with-dual-brushless-motors?_pos=1\u0026amp;_sid=6cfa9131d\u0026amp;_ss=r\"\u003ehttps:\/\/www.kidstoylover.com\/en-us\/products\/yuxiang-f112s-9ch-gps-rc-helicopter\u003c\/a\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eWhat’s in the Box\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x YuXiang F112S Rotor Head Set\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003eInstall Tips\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eDisassembling Main Rotor Assembly:\u003c\/b\u003e Remove the main rotor blades, disconnect the swashplate pitch links, and loosen the main shaft retaining bolt to slide off the old rotor head.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eSeating Feathering Shaft \u0026amp; Dampers:\u003c\/b\u003e Insert the two rubber dampers into the center sockets of the new \u003cb\u003eYuXiang F112S Rotor Head Set\u003c\/b\u003e hub before sliding the feathering (spindle) shaft through.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eSecuring Rotor Head to Main Shaft:\u003c\/b\u003e Slide the assembled head hub onto the top of the main shaft, align the cross-pin screw holes, and tighten the lock screw securely using threadlock.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePre-Flight Tracking Check:\u003c\/b\u003e Reattach the blade grips and pitch linkages, then perform a low-RPM spool-up on a flat surface to verify smooth rotation without head wobbles or vibration.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003eMore Spare Parts \u0026amp; Accessories\u003c\/h2\u003e\n\u003cdiv\u003e\u003cspan\u003eFind remote control，battery，USB，carcase clips，screwdriversand more in the dedicated parts collection：\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ca href=\"https:\/\/www.kidstoylover.com\/collections\/yuxiang-f112s-9ch-gps-rc-helicopter-spare-parts-accessories\"\u003e\u003cspan\u003ehttps:\/\/www.kidstoylover.com\/collections\/yuxiang-f112s-9ch-gps-rc-helicopter-spare-parts-accessories\u003c\/span\u003e\u003c\/a\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003chr\u003e\n\u003cspan\u003e\u003c\/span\u003e\n\u003c\/div\u003e\n\u003ch2\u003eSupport \u0026amp; Warranty\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-month warranty\u003c\/strong\u003e on manufacturing defects\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eShips worldwide\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Kidstoylover","offers":[{"title":"Default Title","offer_id":43703770644547,"sku":null,"price":216.0,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0549\/8313\/1203\/files\/3er_ed11c69e-d4e6-4ecf-ab9d-fe87d0cd0944.jpg?v=1787393408","url":"https:\/\/www.kidstoylover.com\/de-se\/products\/yuxiang-f112s-rotor-head-set-dampers-for-ah-1-cobra-scale-rc-helicopter","provider":"Kidstoylover","version":"1.0","type":"link"}
