Semi British biplane bomber in Rozsyp for motor AXI 2208 class to 12 Classic balsa construction with laser-carved parts, lining paper accessories. Rudder, elevator.
Machine DH-4, Geoffrey de Havilland in 1916 succeeded the famous trick successfully repeated with Mosquito during the Second World War - constructed a light bomber that was so fast and agile, that after throwing bombs could be successfully measured with single fighter. And many even exceeded - eg 14th October 1918 U.S. Marines Lieutenant Ralph Talbot with a single DH-4 downed two and put to flight the other 10 German fighters Fokker D.VII, which earned him the Congressional Medal of Honor, the highest decoration for bravery against the enemy. DH-4 and later improved version DH-9 (with seats pilots closer together for easier communication and better interplay) actually created a standard as a light bomber look, which remained in force until the mid 30th years. Biplane with one or two fixed machine guns synchronized to the pilot, single or double movable machine gun on circulating ring for observer bombs hanging under the fuselage and lower wing ... de Havilland were built en masse in Britain and even larger scale in the USA, where he became the most important fighter aircraft of the newly constructed Air Force. After the war, their continued development - perhaps even us, license built in transport DH-50 with an enclosed cabin for 4 passengers (pilot sat in an open cockpit, to "lose sense of flying").
Kit U.S. firms DUMAS Aircraft is the ideal machine for hobbyists who already has at least basic experience in building small models powered by rubber or piloting gliders and RC model controlled rudder and elevator. You will improve in the works "žbrdličkové" fuselage and wings, paper coating and painting - it goes through highly preprocessed laser engraved works like clockwork.
Kit RC semiscales British light bomber biplane designed to drive the electric motor. The model is simple but classic balsa construction in Rozsyp with laser carved wooden parts, scale accessories from vacuum-molded plastic, plastic parts drawn by injection molding and metal. The hull is constructed normal minimaketářskou technologies from the side of balsa wood glued beams that connect polopřepážkami and bars in the truss frame. The resulting shapes get stuck after a few additional stringers. The wings are the classic design of beams and ribs, tail strips of balsa wood and laser-carved pieces. Minor "tweaks" is making the peripheral parts of the tail and wing tips from balsa wood strips laminated wet. You get so easily surprisingly strong and very light parts - without the use of carbon! Drawings necessary templates again refer. The entire model can be coated paper supplied in the kit or a suitable lightweight iron-on transfer with little shrinkage, such as Airspan or Litespan.
DH-4 is designed to drive small DC motor with gearbox - as the drive unit GWS, which is covered by the plan. Nowadays most likely choose a small AC motor - in this case, you have to be redesigned motor mount (insert a new motor mount from 2 mm birch plywood), but it should not pose a serious problem. For relaxed flying just class motor AXI 2208, and Li-poly two cells 800 mAh. "Namotorování" We recommend not overdoing it - it's a park-flyer, not a rocket.
Kit includes: Laser cut balsa parts, balsa wood beams, vacuum-molded parts (bonnet ...), clear plastic film on the windshield, steel strings on chassis and other small parts, plastic wheels, colored lining paper sheet of stickers, construction plan .
