Hard nose-first landings and accidental ground strikes frequently strip micro gear teeth or push the drive shaft out of alignment, resulting in loud grinding noises, severe vibration, or total loss of thrust during flight. Installing generic gearboxes often leads to improper gear mesh, overheating coreless motors, or loose prop saver fitments. This official \u003cb\u003eSport Cub 500 Gearbox Set\u003c\/b\u003e resolves gear stripping and drive misalignment completely. Engineered to exact factory tolerances, it restores quiet, high-efficiency power reduction, ensuring smooth throttle acceleration and reliable prop saver performance.  \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\u003eFactory-Optimized Gear Mesh:\u003c\/b\u003e High-precision nylon spur gear delivers smooth torque transfer with minimal gear friction and reduced motor strain.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eDurable Hardened Steel Output Shaft:\u003c\/b\u003e Resists bending during minor nose impacts to maintain true propeller rotation without binding.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eIntegrated Prop Saver Mounting Hub:\u003c\/b\u003e Seamlessly pairs with the original Volantex prop saver pop-off adapter to protect blades during crashes.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eDirect EPO Foam Compartment Fit:\u003c\/b\u003e Precision-molded outer housing seats perfectly inside the Sport Cub 500 front cowl without cutting or modifying foam.\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\u003e VolantexRC Sport Cub 500mm 4-Channel RC Trainer Airplane \u003c\/strong\u003eonly.\u003cbr\u003eFull model page (specs \u0026amp; photos):\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.kidstoylover.com\/products\/volantexrc-sport-cub-500mm-4-channel-rc-trainer-airplane-with-gyro-easy-fly?utm_source=copyToPasteBoard\u0026amp;utm_medium=product-links\u0026amp;utm_content=web\"\u003e\u003cspan\u003ehttps:\/\/www.kidstoylover.com\/products\/volantexrc-sport-cub-500mm-4-channel-rc\u003c\/span\u003e\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  Sport Cub 500 Gearbox 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 Worn Gearbox Unit:\u003c\/b\u003e Peel back the nose cowl foam section, disconnect the motor leads from the receiver board, and slide the damaged gearbox assembly out from the fuselage nose mount.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eSeating New Gearbox Assembly:\u003c\/b\u003e Position the \u003cb\u003eSport Cub 500 Gearbox Set\u003c\/b\u003e into the front foam bay, ensuring the outer housing sits flush and parallel to the aircraft center line.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eSecuring Motor \u0026amp; Wiring Harness:\u003c\/b\u003e Align the coreless motor firmly inside the gearbox housing, connect the wire plug to the mainboard socket, and secure the foam cowl using foam-safe glue.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePre-Flight Spin \u0026amp; Prop Saver Test:\u003c\/b\u003e Attach the prop saver adapter and blade onto the shaft, then spin the propeller by hand to confirm smooth, whisper-quiet gear rotation before applying throttle.\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":"Default Title","offer_id":43829523480643,"sku":null,"price":53.0,"currency_code":"QAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0549\/8313\/1203\/files\/f597bf48aa4bef898b0c1a11ccb208b3.jpg?v=1789369916","url":"https:\/\/www.kidstoylover.com\/de-qa\/products\/sport-cub-500-gearbox-set-reduction-gear-for-volantexrc-761-4-trainer-airplane","provider":"Kidstoylover","version":"1.0","type":"link"}
