Severe rotor impacts during crashes can also bend the main shaft or damage internal brushless motor bearings, causing heavy powerhead vibrations that confuse optical flow and GPS stabilization sensors. Finding compatible direct-drive brushless motors with exact shaft length and mounting tolerances is difficult. This official \u003cb\u003eYuXiang F112S Main Motor Set\u003c\/b\u003e directly restores factory flight efficiency and power. Featuring a high-torque brushless motor pre-fitted with a precision main shaft, it provides smooth, low-noise power delivery directly to the main rotor system without gear slip or power loss. \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\u003eHigh-Efficiency Brushless Direct-Drive Motor:\u003c\/b\u003e Delivers smooth, instant torque and high thermal efficiency for stable head speeds during scale 3D and GPS hover flights.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eStraight Hardened Main Shaft:\u003c\/b\u003e Pre-aligned main shaft ensures zero axial runout, suppressing drivetrain vibration to protect gyro and GPS sensor data.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eDirect-Fit Plug Harness:\u003c\/b\u003e Pre-wired with original factory gold-plated motor connectors for instant, solder-free connection to the ESC\/receiver system.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eComplete Replacement Power Kit:\u003c\/b\u003e Includes 1x Brushless Main Motor, 1x Integrated Main Shaft, and 1x Hex Socket Cap Screw for secure installation.\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 Main Motor 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\u003eRemoving Damaged Motor \u0026amp; Shaft:\u003c\/b\u003e Disconnect the motor wiring leads from the main board, loosen the main shaft retaining hardware, and carefully slide the worn motor unit out of the frame.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eSeating New Brushless Motor:\u003c\/b\u003e Position the \u003cb\u003eYuXiang F112S Main Motor Set\u003c\/b\u003e into the main frame motor bay, ensuring proper clearance around internal wiring and frame walls.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eSecuring Main Shaft Fastener:\u003c\/b\u003e Align the main shaft cross-hole with the upper drive\/hub assembly, thread the included hex socket cap screw through, and tighten securely using threadlock.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePre-Flight Rotation \u0026amp; Power Check:\u003c\/b\u003e Plug the motor leads into the ESC, spin the rotor head by hand to confirm smooth bearing rotation, and perform a low-throttle spool-up to check for vibration-free power delivery.\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":43703770939459,"sku":null,"price":98.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0549\/8313\/1203\/files\/7er.jpg?v=1787394063","url":"https:\/\/www.kidstoylover.com\/hi-nz\/products\/yuxiang-f112s-main-motor-set-brushless-motor-shaft-for-ah-1-cobra-rc-helicopter","provider":"Kidstoylover","version":"1.0","type":"link"}
