In our circle beginners-students who have gained initial skills training cord model engine MK-17, traditionally entrusted with the Assembly of models of air combat with the same engine. In this sports class is most often used layout type “flying wing”: lomikami wing and Elevator on the trailing edge of the wing. Spar-wall this model is made from spruce, pine, aspen or lime plate thickness of 2.5 mm, and the rear edge of the wing—rails section 12×3 mm. the Latter consists of centroplane and console parts. Joints edge definitely wrapped thread and impregnated with glue, or with rough landings inevitable failure. The wing tip is made of plywood or wood plates with a thickness of 2.5…3 mm is recommended to facilitate Their holes. If the rib is cut from plywood, the edges are not required.
The ribs are cut on a pre-prepared templates. In terms of mug is very convenient — don’t have to spend time on the layout of the circuits. Besides, ruining the workpiece, it’s easy to repartition any detail. (That’s why in the circle it is desirable to have a set of templates for all the major details: a spar, rib, tip, Elevator, Central rib, a rocking chair, scan the fuel tank, lobiki wing.)
To make the ribs can be of various materials: plywood with thickness of 2…3 mm foam stamps SS-4-40 and PVC piping with the obligatory contour thin rails or otlu whelping veneered construction plywood. In recent time there is another promising material — corrugated cardboard, which is packaged in TV, video and office equipment. This material is very lightweight, durable and well kleetsya.
First, the templates are plotted the contours of the ribs, then the excess is trimmed and the workpiece and fringes as well as foam. With this technology you can make and Elevator.
