Airframe The airframe is completely made of composite material which excels in its specific strength and excellent fatigue properties. The entire aircraft can be broken down into individual units, i. e., both halves of the wing and tail surfaces, including stabilizers, can be separated from the fuselage to ease aircraft transport. Wing Wing area has a modern laminar profil NACA HDF. This profile along with a slightly trapezoidal plan and precise surface quality have a significant interest in the high performance of the machine. The aerodynamic design of the wing gives to the airplane good fall characteristics. The separation of air flow in the critical angle of slope happens at the root of the wing. This ensures good handling of the machine until it drops and symmetrically stalls. The wing is a cantilever design with two cavities, which significantly increases the torsional strength. The flanges are made of carbon rowing. The cover of the wings is made of glass and carbon sandwiches, therefore there are no ribs in the wing. FIXED GEAR, FOR FLIGHT SCHOOLS The fixed gear version of VL3 is designed for flight schools. Your students will learn faster since the VL3 is really easy to fly having an incredible low stall speed and short landing roll. PROPELLER You can choose between a fixed or variable pitch propeller. The propeller is adjustable in-flight to enhance your climb and cruise performance. Its adjustability will also shorten your take-off distance.For best results install the Rotax 915, hydraulic governor and Woocomp KW31 hydraulic propeller.
