Dedicated to the memory of General designer Mikhail Kuzmich Yangelya. In issue No. 7 of 2000 published an article “the workhorse of the launch sites” dedicated booster light class — “Kosmos-3M”. It’s time to tell the readers more about the earlier work (now quite forgotten), the famous Dnepropetrovsk CB “South”— the first Russian carrier rocket light class that took indexes 63С1 and 11К63 and an open name “Kosmos-2”. In this article the author talks about the rocket when it is presented the detailed drawing, executed on full-scale model, on display in the National aerospace education center of Ukraine in Dnepropetrovsk.

The device allows you to monitor the status of the galvanic cells and batteries: it measures the voltage under a nominal load. Diagram of the device is a voltage divider made from resistors. Using the B1 resistors are switched in pairs: one acts as the load, and the second determines the sensitivity of the device.
The starting point of any design and experimental work, whether a solid CB or technical circle, a laboratory for students — identifying the problem, the technical problem. Based on experience WITH an CUT, try to identify the conditions that determine the success of children’s technical creative work.
The glorious pages of military Chronicles of the Soviet Army and Fleet will be reflected in the summer pioneer games and competitions the jubilee. Young modelers and designers can show their ingenuity in the preparation and technical design of these games — including water maneuvers “Lightning”. We published several examples of homemade products that are easy to force themselves yunarmeytsev “Lightning”.
Hydroplanes BRO-16 — single-seat biplane of wooden construction, designed for training and demonstration and training flights. This is the first machine of this type, established in the Lithuanian SSR under the guidance of famous designer, a veteran of the Soviet gliding of Bronica Oskinis.
The desire to create something unusual and striking, inherent, perhaps, to each of the modelers. This made sense at the time to try to find a new class of radio controlled gliders, which after years of occupation began to seem quite similar. Some time ago on paper there were projects non-motorized flying wings unusual geometry and several gliders-ducks. However, knowing that the process of creating a glider of any class more demanding than the aircraft, did not want to go on a risky experiment – flight properties of such extravagant cars were unpredictable.
Model glider Oktyabrenok (Fig. 1) simple in design. It can build every student. Needed for the production of pine slats, some plywood and tissue paper. And best of all such models to build model aircraft kit-parcel No. 15 (price 3 R 80 K.). It is possible to build a 12-15 models.
