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.
German river motor yacht “bar-new” (Warnow) was the inspiration great procopii, equipped with an electric motor and two channel radio control equipment. She was repeatedly reproduced by modelers and enjoyed great success at competitions and demonstrations. In the absence of radio equipment with the model it is possible to speak in the classroom “bramahadev”. The design model is simple. With its manufacture and Assembly can handle every aspiring constructor of ship models. The case is of classic design, stacked wooden. Collect it on the epoxy. Mounting up the keel on a flat Board-berth with a fixed drawing with the layout of the centerline and locations of frames from the 1st through the 6th. All of the parts of the frame previously marked in accordance with drawings, cut out and treated.
It all started with the fact that we are a young childless family bought two “Kama” and became interested in Cycling. With the birth of his daughter had to solve the task: how to travel together? Did a little chair, and set it on the rear trunk. It has served us faithfully for several years But the daughter grew up, and sit in the car seat she was cramped, uncomfortable, the idea of creation of easy folding, durable enough trailer stroller, quickly attachable to the bike.
Associate Professor of the Department “Technology of mechanical engineering” of the Mari state technical University M. L. Popov, having a great experience with Bicycle sport, sent a letter to the editor which described and theoretically substantiated his view on the problem of improving the reliability of the bearing unit of the carriage. Today we publish only constructive and technological proposal of the author. More than 20 years of experience continuous all-weather and all-season operation of my bike model-542 “Sport” issued in 1974, the total mileage of which amounted to about 100 thousand km, as well as analysis diary entries have led to the conclusion that the bottom bracket for reliability is in fourth place after floreina, driven sprocket and drive chain.
