EWW-180 also known as the Whitewing is the evolution of The Blackwing. This 3D printed UAV flying wing is powered by a small EDF motor that allowed us to design a very clean and aerodynamic flying wing. Nevertheless you can also get the propeller version. Both versions can be interchanged because the wing is detable thanks to an innovative and totally 3d printed locking mechanism patented by Eclipson Airplanes, the system is as simple as effective and the airflow will ensure that the latch is closed during the flight. The aerodynamic has been improved mainly thanks to the use of a nonlinear wing torsion, a higher aspect ratio and a lower static margin that was possible due to the use of winglets, this airplane reach the impressive glide ratio of 19 to 1 at 40 km/h (PLA version), this means that the aircraft can not be used only like UAV/FPV model but also like a motorglider.  Despite the glide ratio of the PLA version is higher it is recommendable to print the lighter hybrid version where non loaded parts can be printed with LW-PLA. This way you will get a more adequate thrust to weight ratio and more flight time.
