All-around radio controlled model gliders (class F-3-B), which includes three flight exercises, is the youngest species of the competitions of flying models. It is flying on the duration, distance and speed. Place in the competition is determined by the sum of the results of the three exercises shown in the two flight rounds. In competition an athlete may use two models: allowed rearrangement of parts from one to another, however, the weight of the model and the maximum area of bearing surface shall not exceed respectively 5 kg and 150 DM2, and the load on an area of 12 and 75 g/DM2. The rules allow change of the geometry of surfaces in flight using radio control, but the transmission of information from the Board to the pilot is prohibited. The model was run for the guard rails, the movement of the Modeler’s assistant, engaged in towing, shall not exceed 150 m. a climb can be carried out with the help of the engine, for every 1 cm3 working volume of which (but not more than 2 cm3) shall be at least 100 g take-off weight of the model. It allowed the use of additional ballast. The engine operating time is limited to 45 C. To complete the exercise on the duration of the flight, the Modeler is given 8 min of working time at the start. The countdown of flight begins with the uncoupling of a rail (or stop the engine of a motor-glider). Every second in the air is estimated at one point. The maximum number is 360. For a flight over 6 min, the Modeler receives one penalty point for each extra second in the air (down to zero).THE TRAP SAWDUST
When drilling holes in vertical parts or concrete wall is not so easy to demonstrate the accuracy and not to make a mess. However, this method makes it easy to solve this problem. Take any flat jar with lid — e.g. an empty box from under the Shoe-Polish, — and pressed her to the wall, Read more…
On the ridge of the roof of the house I made a weather vane Carlson. The design is very simple to manufacture. The “Carlson” produced from a metal sheet thickness of 2 mm. the Figure and the rod from the rod Ø8 — 10 mm rigidly riveted together. As the rotation unit used the wheel hub of a Bicycle wheel with bearings. Below is rigidly secured large fishing bells (indicated on sketch). The same bell in hand “Carlson”. From the natural vibration during the rotation of the propeller and in the wind all the bells are ringing.
“Bespectacled” they know that most victims are not glass and frame: breaks down on the bridge of his nose, bursts into tight spots. If no spare points, you can use a simple Express repair. Take a thin paper clip and pliers to bend the little brackets. Taking the tweezers, heat the clip over a flame and allowing to cool, gently press the ends into the frame on both sides of the crack. If the bracket included will not completely push her soldering tip, again she will be warm and will easily sink into the plastic.
The conduct of hostilities rivers are a serious obstacle to the attacking side. Not accidentally during the Second world war, a powerful defensive lines were built on their shores; suffice it to recall the well-known German Eastern wall, an important part of which became the Narva river, Sozh, Dnieper and Dairy. It is significant that after the victorious conclusion of the Battle of the Dnieper which lasted from August to December 1943 for heroism 2438 most distinguished soldiers, sergeants and officers all the armed forces was awarded the title of Hero of the Soviet Union (in just four years of the great Patriotic war awarded the gold Star medal were 11 603 warrior).
Model missiles Ѕ3А Cup winner S. P. Korolev 2008 Igor Danilov made by well-known scheme called “Chelyabinsk”. Its main feature, distinguishing feature is elongated up to 165 mm tail section. This helped a little to alleviate (about 0.5 g) stern, to shift the center of gravity of the model up.
Diverse and numerous family water bikes, but they all have a major flaw: transport them by land very difficult. Another thing — ampipe, on land he feels as confident as on the water. The secret to this versatility in the propeller — crankshaft with propeller wheels when traveling on the roads is the leading “front axle”.
Drill — an excellent universal drive for a variety of devices. In our magazine we published the suggestions of readers on how to expand the scope of this tool. Today we will talk about lawn mower, driven by the same drill.
