The attachment connects the propeller to the engine so that the spinning motion creates thrust. The design focuses on being strong, lightweight, balanced, and easy to build. Different designs will be tested to see how they affect the engine's performance and how well the propeller spins. This project uses basic engineering and aerodynamics to improve the efficiency of the engine and show how a well-designed attachment can make it perform better.\u003c\/p\u003e\u003cp\u003eDesign by Ghosty on MakerWorld (license: BY-SA).\u003c\/p\u003e","brand":"Mymadmanlab","offers":[{"title":"Default Title","offer_id":67398874759472,"sku":null,"price":4.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/0809\/5280\/files\/0_f039a79b-81ae-4713-916a-3ac64cb639cf.png?v=1784892187","url":"https:\/\/mymadmanlab.com\/products\/propeller-for-balloon-radial-engine-by-slava-z","provider":"Mymadmanlab.com","version":"1.0","type":"link"}
