Silent-3.4M Ultra light weight glider. It's clean low drag design and wing based on SD7080-modified airfoil provides excellent air penetration with wide range of speed. Flying weight ~990 g (~34.7 oz.) makes it an ultimate multi-task thermal glider. This original, and very modern construction is a statement to years of experience in designing and active competition.
Glider has composite fuselage pod (epoxy/glass with carbon-fiber reinforcements). The fuselage pod features slip-on nose cone for easy access to radio gear and is 2.4GHz friendly. Its strong tapered tail boom, horizontal stabilizer mount and vertical stabilizer are made of carbon fiber composite. The horizontal stabilizer with pre-hinged elevator and rudder are made from selected balsa wood and fully laminated for lightness and durability. The wing cores are precision cut from special high-density white polystyrene foam and for superb strength wings have molded in carbon/glass composite spars. The black poplar veneer is bonded to the foam with aircraft industry grade epoxy in high pressure mold for perfect airfoil fidelity and warp-free wing. Our original 3-segments wing design is very strong and convenient, internally hinged ailerons and flaps are minimizing building time. The 3-segment wing and removable horizontal stabilizer allows easy storage and transport flexibility.
