DSA-1 Smith Miniplane

he model is a single amateur model biplane DSA-1 with the registration N391Y. The prototype designed and built in 1957 by Frank Smith as a plane for pleasure. Designation DSA-1 (Damned Small Aeroplane - a "damn small plane '") sufficiently describes the airplane. The design allows a skilled amateur simple average of the normal construction material using ordinary tools. Although not strictly plane aerobatic specials, is capable of full aerobatics. The success of a prototype inspired designer to build the next piece of documentation and training for amateur construction, projects already completed but not enough. Fortunately, it took care of his son with friends. According to the documentation was built many Miniplanů which vary engine installation, chassis, equipment, etc.. Three-view drawing template with technical data and description of color in the Modeler 6 / 1987. The model is considerably simpler to master. The aim was to build a light sport biplane with minimal consumption of balsa and less maketovými details on which I wanted to verify the technology to work with polystyrene foam, the location of muffler to the engine casing and a biplane flight characteristics. Although the model is relatively small (it can be transported assembled in the rear Skoda), pleasantly surprised the flight characteristics. For those who have tasted the magic of two wings, it can be the first biplane. The construction is subject to easy and fast construction. The basic material is polystyrene foam. For cutting polystyrene cutter is needed with resistive wire with a width cut at least 1 000 mm. There are other technologies for sticking polystyrene, which can of course also be used. Motor cover produce polystyrene laminated on foot or in a negative form. Consists of a balsa fuselage sides, plywood partitions and solid cover. Both wings are made of foam. The tail surfaces are celobalzové, classic design. The chassis is made of steel wire soldered. The prototype was used standard series engine MVVS Model 6.5 F. Scale muffler layout, no detail, because it depends on the type of engine options and modelers. Flight characteristics are good model: it can handle anyone who has experience with the trainer vícepovelovým model with winglets. The model is capable of basic aerobatic maneuvers except for mock-spin.
