Category S4. The rocket plane is an aircraft that is lifted into the air using the thrust of the rocket engine, and returns to earth planning with the engine off — using the aerodynamic lifting force. This requirement applies to all three categories of rocket gliders for the duration of the flight — S4, S8, S10. And each has its differences. S4 — model glider with an accelerator, which can be separated during the flight. S8 — model RC rocket glider S10 — a model rocket with a soft wing (wing “Rogallo”).

To run the motor manually? And fingers will discourage, and not always with a half-turn wind up cranky diesels. And the competition time limit to run very hard. Did not fit in the allotted minute — and-goal instead of numbers in judicial protocols appear null.
In the summer of 1981 in Moscow took place the traditional competition for experimental model airplanes. Today we introduce you to models — winners of these competitions. Student A. Bobrov from the city of Khimki (Moscow region) constructed a model glider “flying wing”, which showed at the competitions best results. Over five rounds were demonstrated following the duration of the flight: 81+16+28+180+130 = 435 C.
Fluorescent energy-saving lamps in recent years become increasingly popular, despite its relatively high cost. Indeed, all the good these lights are, but the one absurdity of spoiling their reputation. Adapted standard electroputere E27 bulb (photo 1) are too large (diameter) of the Central contact area and when screwing them into the cartridge cases when the site closes both contact.
Many advantages in this model of micro-motors of the type
For tourists and skiers in big mountains with difficult terrain and significant elevation usually put a chairlift. At its traction-bearing rope they have special hangers with one or two armchairs. The length of such lifts is limited to 1.5—2 km: experience has shown that the rise in excess of time 10-15 minutes, can during winter lead to trouble — frostbite unprotected skin, especially the face.
In the mid 50-ies of the last century, the magazines wrote that the burned out light bulb is a real treasure for lovers to make all their own hands. In particular, it was reported how to do from her flask retort magnifying glass and other very useful things. Nowadays a genuine treasure for homebrew are … used disposable medical syringes. It is no secret that they are already being applied by the craftsmen as greasers, neat coils, easy to install circuit boards. Sure, a decent place can take these syringes and in the Arsenal of computer geeks when filling cartridges inkjet printers, which (I speak from experience) are difficult at home. It is most difficult when filling is black (by the way, the most common) color.
As you know, in a two-stroke motorcycle engines bearing-connecting rod is one of the most loaded nodes. At the same time, its technical condition depend on time and the quality of the engine. To determine the wear and furthermore make the necessary repairs without dismantling the crankshaft is almost impossible.
