This official RC ERA A61 Main Shaft set is designed to replace wobbling or stressed shafts that occur after a hard landing. By ensuring a perfectly straight rotation of the rotor head, this replacement part eliminates mechanical jitter, allowing the altitude hold and optical flow systems to function with factory-standard precision. \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=\"9,0,0\"\u003e\u003cb data-path-to-node=\"9,0,0\" data-index-in-node=\"0\"\u003eHigh-Strength Carbon Steel Construction:\u003c\/b\u003e The main rod is crafted from reinforced steel to resist bending during high-speed rotations and minor impacts.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"9,1,0\"\u003e\u003cb data-path-to-node=\"9,1,0\" data-index-in-node=\"0\"\u003ePrecision-Toleranced Collar:\u003c\/b\u003e Includes a perfectly sized mounting collar that ensures the shaft remains vertically secure, preventing \"up-and-down\" play in the rotor system.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"9,2,0\"\u003e\u003cb data-path-to-node=\"9,2,0\" data-index-in-node=\"0\"\u003eSeamless Gear Integration:\u003c\/b\u003e The shaft diameter is specifically calibrated to fit the A61 main gear and swashplate, ensuring zero-latency power transfer from the motor.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp data-path-to-node=\"10,0,0\"\u003eFor the\u003cstrong\u003e RC ERA A61 Optical-Flow RC Helicopte\u003c\/strong\u003e only.\u003cbr\u003eFull model page (specs \u0026amp; photos):\u003cbr\u003e\u003ca href=\"https:\/\/www.kidstoylover.com\/en-us\/products\/rc-era-a61-optical-flow-rc-helicopter-altitude-hold-2-4ghz-1-3-batteries?_pos=1\u0026amp;_sid=c43b92f8e\u0026amp;_ss=r\"\u003ehttps:\/\/www.kidstoylover.com\/en-us\/products\/rc-era-a61-optical-flow-rc-helicopter\u003c\/a\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eWhat’s in the Box\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1* Main Shaft 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 data-path-to-node=\"11,0,0\"\u003e\u003cb data-path-to-node=\"11,0,0\" data-index-in-node=\"0\"\u003eShaft Alignment:\u003c\/b\u003e When sliding the steel shaft through the bearings, ensure it moves freely without resistance; if you feel friction, check the internal bearings for damage.\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\"\u003eCollar Securing:\u003c\/b\u003e Secure the white mounting collar tightly to eliminate vertical play; even a small amount of vertical movement can cause the helicopter to drift while using altitude hold.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,2,0\"\u003e\u003cb data-path-to-node=\"11,2,0\" data-index-in-node=\"0\"\u003eLinkage Check:\u003c\/b\u003e After replacing the shaft, re-verify the levelness of the swashplate and the tightness of the rotor blade screws to ensure a safe first flight.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\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":"black","offer_id":43038908776515,"sku":null,"price":51.0,"currency_code":"HKD","in_stock":true},{"title":"white","offer_id":43038908809283,"sku":null,"price":51.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0549\/8313\/1203\/files\/acbcbc92-50a2-4c85-a4e3-45245195d46b.webp?v=1775471831","url":"https:\/\/www.kidstoylover.com\/en-hk\/products\/rc-era-a61-optical-flow-rc-helicopter-main-shaft-set-replacement-spare-part","provider":"Kidstoylover","version":"1.0","type":"link"}
