Since i was child i used to go to rc models flying fields to see these wonderful machines repeating my self that one day also i will be part of this reality, in 2015 I decide to begin the desing of my own plane, the SF-40L.
After two years of test, design, building in 2017 I obtained the complete first prototype.
The 6 october 2018 the second and definitive prototype made its maiden flight paying off years of work.
The plane is completely made off wood, the main body has a cassette structure made of 4mm plywood while the wing and the aerodynamic surfaces are made of balsa wood with a traditional "ribs and spares" solution covered with both balsa panel and Oracover film, it is motorized with an outrunner brushless motor and has a weight of 2.54 Kg with the LiPo battery
