Silent-E 3.4M Ultra light weight electro-glider F5J class. It's clean low drag design and wing based on SD7080-modified airfoil provides excellent air penetration with wide range of speed. Flying weight ~1300 g (~45.6 oz.) makes it an ultimate thermal electro-glider. This original, and very modern construction is a statement to years of experience in designing and active competition.
The fuselage pod and vertical stabilizer are made from pre-painted, molded, composite materials (epoxy/glass-carbon-fiber).
The fuselage pod features removable canopy for easy access to radio and drive gear and is 2.4GHz friendly.
Its strong tapered tail boom is made of carbon-glass-fiber composite. 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 the building time.
