Over long hours of scale flying or during sudden, high-stress landing tip-overs, the small composite mounting arms on a stock head can warp, stretch, or sustain microscopic stress fractures. This introduces mechanical slop into the blade grips, causing uneven blade tracking, lazy pitch responses, and high-frequency fuselage vibrations. For the 1\/48 scale RC ERA C184 MD530, such vibration directly spoils the positioning telemetry captured by the downward-facing optical flow camera sensor. Swapping out your worn hub with this factory-fresh, perfectly true 4-blade replacement head completely eliminates steering slop, locking back in the rock-solid hovering precision your scale helicopter possessed on day one. \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\u003eReinforced 4-Blade Symmetric Cross Matrix:\u003c\/b\u003e Molded into an ultra-precise cross geometry that anchors all four blade grips at perfect 90-degree offsets for stable aerodynamic tracking.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eHigh-Density Self-Lubricating Engineering Polymer:\u003c\/b\u003e Injection-molded from a premium composite matrix designed to resist stretching under heavy centrifugal high-RPM flight loads.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eFlawless Zero-Flex Drive Collar Fitment:\u003c\/b\u003e Features a perfectly tolerance-matched central main shaft sleeve channel that eliminates wobbles between the drive axle and the rotor assembly.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eLow-Inertia Weight-Optimized Core Profile:\u003c\/b\u003e Keeps rotational mass down to minimum factory baselines, significantly reducing torque load spikes on your brushless main motor and extending battery runtime.\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\u003eRC ERA C184 MD530\u003c\/strong\u003e only.\u003cbr\u003eFull model page (specs \u0026amp; photos):\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.kidstoylover.com\/collections\/rc-era-c184-rc-helicopter-spare-parts-accessories\"\u003ehttps:\/\/www.kidstoylover.com\/collections\/rc-era-c184-rc-helicopter-spare-parts-accessories\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 RC ERA C184 Rotor Head\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\u003eStripping the Old Multi-Blade Assembly:\u003c\/b\u003e Use your micro tools to pop off the five cyclic pushrod linkages; unthread the feathering shaft spindle hardware screws to detach your main blade grips from the worn central hub block.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eMain Shaft Seating and Lock Pin Insertion:\u003c\/b\u003e Slide the new black 4-blade rotor head piece straight down onto the top of the steel main rotor shaft; carefully align the horizontal cross-drilled mounting holes and push the silver lock pin through to prevent vertical slippage.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eReassembling Blade Grips and Linkage Arms:\u003c\/b\u003e Slide your blade grips over the four cross-stems of the new hub matrix; thread your retaining screws back in until snug, and snap the ball ends of your pitch linkages back onto the steering ball studs without twisting the plastic cups.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePre-Flight Tracking and Sensor Calibration:\u003c\/b\u003e Place the reassembled MD530 model onto a flat, non-slip workbench mat; spin the main blade system by hand to ensure a perfectly level plane, then run a slow spool-up to confirm that the fuselage runs vibration-free, enabling your downward optical flow tracking lens to lock its coordinates smoothly.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003eSpare Parts \u0026amp; Accessories\u003c\/h2\u003e\n\u003cp\u003eFind remote control，battery，USB，carcase clips，screwdriversand more in the dedicated parts collection\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.kidstoylover.com\/collections\/rc-era-c184-rc-helicopter-spare-parts-accessories\"\u003ehttps:\/\/www.kidstoylover.com\/collections\/rc-era-c184-rc-helicopter-spare-parts-accessories\u003c\/a\u003e\u003c\/p\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":"Default Title","offer_id":43425553645635,"sku":null,"price":74.0,"currency_code":"BRL","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0549\/8313\/1203\/files\/C186_per.jpg?v=1781750083","url":"https:\/\/www.kidstoylover.com\/pt-br\/products\/4-blade-main-rotor-head-hub-replacement-for-rc-era-c184-md530-helicopter","provider":"Kidstoylover","version":"1.0","type":"link"}
