The set includes two wheels, each with a 5.5 mm axle hole and a tire thickness of 40 mm. The super light sponge outer ring reduces overall weight, helping the model stay airborne longer, while the plastic hub provides enough strength for landing loads.\u003c\/p\u003e\n\n\u003ch2\u003eWhat are the exact dimensions and axle size?\u003c\/h2\u003e\n\u003cp\u003eEach wheel measures 128 mm in diameter (roughly 5 inches) and 40 mm in thickness. The axle hole diameter is 5.5 mm, which fits many standard RC landing gear axles. Check your axle size before ordering — the hole is fixed at 5.5 mm and may not work with smaller or larger axles without modification.\u003c\/p\u003e\n\n\u003ch2\u003eWhy use PU sponge over solid rubber or foam?\u003c\/h2\u003e\n\u003cp\u003ePU sponge is noticeably lighter than solid rubber, which matters for RC airplanes where every gram affects flight performance. It also offers a firm yet slightly compliant feel, providing grip without adding bounce. The tread pattern on these tires is designed to be anti-skid and wear-resistant. The plastic hub is harder than foam wheels, so it holds its shape under the model's weight during takeoff and landing.\u003c\/p\u003e\n\n\u003ch2\u003eApplication tips for RC planes and cars\u003c\/h2\u003e\n\u003cp\u003eThese wheels work well on light to medium RC airplanes (park flyers, small scale warbirds), helicopters with tail wheels, and some RC cars where low weight is a priority. Because the tire is soft sponge, it may wear faster on rough asphalt than rubber. For grass or dirt runways, the grip is good and the wide 40 mm footprint helps stability. The set comes with two identical wheels and hubs — no additional hardware is included.\u003c\/p\u003e\n\n\u003ch2\u003eQuick specs\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDiameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e128 mm (5 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eThickness\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e40 mm (1.57 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAxle hole\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTire material\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePU sponge\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eHub material\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePlastic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eQuantity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2 wheels with hubs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eAre these wheels compatible with 3 mm axles?\u003c\/h3\u003e\n\u003cp\u003eThe axle hole is 5.5 mm, so a 3 mm axle would be too small. You would need a bushing or adapter to fit securely.\u003c\/p\u003e\n\u003ch3\u003eCan I use these on a heavy RC truck?\u003c\/h3\u003e\n\u003cp\u003eThey are intended for lightweight models — RC airplanes and small cars. A heavy truck (over 3-4 kg) may deform the foam or stress the plastic hubs. For heavier vehicles, look for rubber or solid foam tires.\u003c\/p\u003e\n\u003ch3\u003eDo the wheels come with bearings?\u003c\/h3\u003e\n\u003cp\u003eNo, the package contains only the tire and hub assembly. Bearings are not included. The hub runs directly on the axle — lubricate if needed.\u003c\/p\u003e\n\u003ch3\u003eHow do I mount them?\u003c\/h3\u003e\n\u003cp\u003eSlide the 5.5 mm hole onto a compatible axle and secure with a wheel collar or retaining clip. The plastic hub is not threaded.\u003c\/p\u003e\n\n\u003cp\u003eThese Fielect wheels are a practical, light choice for hobbyists building or upgrading RC aircraft who want to shave off a few grams without sacrificing landing durability. The pair provides consistent ground handling and easy installation.\u003c\/p\u003e","brand":"Fielect","offers":[{"title":"Default Title","offer_id":58074939097391,"sku":null,"price":25.73,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0986\/4478\/7503\/files\/fielect-5-inch-rc-airplane-wheels-with-pu-sponge-tires-and-plastic-hubs-2-pack-1.jpg?v=1781476555","url":"https:\/\/toysforkid.co.uk\/products\/fielect-5-inch-rc-airplane-wheels-with-pu-sponge-tires-and-plastic-hubs-2-pack","provider":"Toys For Kid","version":"1.0","type":"link"}
