The model shows how everything works together: five pistons move in the real firing order 1-3-5-2-4, the valves open and close in sync via metal pushrods, and the propeller turns smoothly. Power comes via USB-C, the switch sits in the base. The propeller has a safety clutch that disengages under resistance.\u003c\/p\u003e\u003cp\u003eA project for engineering fans – 470 parts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHighlights:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eReal firing order 1-3-5-2-4\u003c\/li\u003e\n\u003cli\u003eSynchronised valve train with metal pushrods and compression springs\u003c\/li\u003e\n\u003cli\u003eElectric motor with USB-C, on\/off switch in the base\u003c\/li\u003e\n\u003cli\u003ePropeller with safety clutch\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAssembly without glue or tools, instructions in 11 languages.\u003c\/p\u003e","brand":"Ugears","offers":[{"title":"Default Title","offer_id":57378787361033,"sku":"70283","price":86.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0361\/4100\/6988\/files\/R-5AircraftEngine1x1.jpg?v=1791291768","url":"https:\/\/www.ugears.de\/en\/products\/r-5-flugzeugmotor","provider":"UGEARS.de","version":"1.0","type":"link"}
