The firm Waco Aircraft Company, located in Waco, Texas, in the thirties, except transport cabin biplanes and jedenapůlplošníků also produced a series of two-digit type training and aerobatic biplanes, which were produced for the military under the name of PT-14th The culmination of the prewar production was the kind of acrobatic YMF 1934 extended hull. Although the original company Waco disappeared after the war, the desire to own US pilots biplane noble shapes gave rise WACO Classic Aircraft Company, which since 1986 resumed the production of reconstructed and newly certified models YMF-fifth
Designers of American companies DUMAS Aircraft is the ideal machine for modelers who already has more experience in building small models powered by rubber or piloting gliders and RC model controlled rudder and elevator. You will improve in the building "žbrdličkové" skeleton of the fuselage and wings, paper coating and painting - it's due to highly preprocessed laser-carved works like clockwork.
RC kit semiscales American aerobatic biplane designed for electric propulsion. The model is a classic balsa structure in Rozsyp with laser carved wooden parts, scale accessories made of vacuum-molded plastic parts drawn by plastic injection molding and metal. The hull is constructed of conventional technologies minimaketářskou sides of balsa wood glued beams that connect polopřepážkami and bars in the lattice frame. The final round shapes get after sticking a large number of additional stringers. The wings are the classic design of the spars and ribs, tail out of balsa wood strips and laser-carved parts. Minor "tweaks" is making the peripheral parts of the tail and wing tips of balsa wood strips laminated wet. You get so easily surprisingly strong and lightweight parts - without the use of carbon! Drawings necessary templates again refer to the instructions. The whole model can drag the paper supplied in the kit or a suitable lightweight iron sheets with little shrinkage, such as Airspan or Litespan.
Waco YMF is designed to drive the DC motor series "280" with the gearbox, which is covered by the plan. Nowadays probably choose small AC motor - in this case you will have to redesign the motor mount (insert new motor mount from 2 mm birch plywood), but it should not pose a serious problem. For relaxed flying just class motor AXI 2212 and Li-poly tříčlánek 800 mAh. "Namotorování" We recommend overdoing it - it's a park-flyer, not a rocket.
Kit includes: laser carved balsa parts, balsa wood beams, vacuum-molded parts (bonnet ...), clear plastic film to the windscreen, steel strings on chassis and other small parts, lightweight foam wheels, colored lining paper sheet of stickers, construction plan.
