The inverse tip design helps to reduce blade tip vortex and the light weight of the propeller means it has a smaller moment of inertia and fast response time.\u003c\/p\u003e\r\n\u003cp\u003eGemfan designers use CATIA modeling software and Ansys Fluent to design their Flash propeller airfoils and blade style. Combining the most effective airfoils with different motors to get the most iterations on their design. Testing factors such as surface pressure, airfoil optimization, lift force, resistance, and torque have resulted in the Flash series - made just for racing.\u003c\/p\u003e\r\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eItem name: flash 7042 2-blade propeller\u003c\/li\u003e\r\n\u003cli\u003eSize: 7042, 7.0x4.2\u003c\/li\u003e\r\n\u003cli\u003eMaterial: PC\u003c\/li\u003e\r\n\u003cli\u003eWeight: 5.48g\u003c\/li\u003e\r\n\u003cli\u003eMounting hole: 5mm\u003c\/li\u003e\r\n\u003cli\u003ePaddle size: 14mm\u003c\/li\u003e\r\n\u003cli\u003eHub thickness: 7.5mm\u003c\/li\u003e\r\n\u003cli\u003eSuitable for 2407-2408 motors\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003ch2\u003eIncludes\u003c\/h2\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e2x Gemfan Flash 7042 Durable 2 Blade CW\u003c\/li\u003e\r\n\u003cli\u003e2x Gemfan Flash 7042 Durable 2 Blade CCW\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"Gemfan","offers":[{"title":"Default Title","offer_id":45515398119654,"sku":"8109","price":5.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0698\/9525\/8342\/files\/7042-2-black.jpg?v=1734559196","url":"https:\/\/shop.lumenier.com\/products\/gemfan-flash-7042-durable-2-blade-black-set-of-4","provider":"Lumenier","version":"1.0","type":"link"}
