In a vast range of car alarms has recently introduced a good system Mongoose Duplex 3D models with the function of a pager device, remote audio message to the key FOB that the car owner of unauthorized door opening, engine start, shock the body, etc., a Distance alert in the face of massive urban development (on example of Saint-Petersburg, Russia) not less than 300 m. In the daily operation of the alarm system with a pager is convenient because the alarm comes on, the bidirectional remote control unit (RCU) is a key chain held by the owner of the car (except for a loud audible alarm in the vehicle which can be reprogrammed for quiet mode). Thus, there is no need to jump to the car or to the window each time it is triggered car alarms, worrying for his “swallow” (it is known that the set of sound signals of various alarm systems is no different variety). If it works it is “your” alarms — this will be seen by the alarm on your remote-the keychain remote, and the flash indicator LEDs will indicate a specific area of the triggered zone of protection. It agree, it is convenient.IMPROVE THE ALARM

To fly like a bird, the strength of your muscles, very tempting; dreamed about it many of our ancestors. Already in the XV century, when on flights in the modern sense could not even dream of such a machine designed by Leonardo da Vinci. Unfortunately, he was not able to implement their ideas. And only today, after five centuries, people have achieved the first real success.
In the footsteps of virtually every information, published under the heading “ENEA — young innovator”, the editor receives many letters. On the envelope address NTTM, young innovators, enterprises, construction companies, farms, and all of them interested in more information about printed in the journal innovative developments. And United by the desire to apply them to achieve a new increase productivity, improve technology, product quality.
This simple and reliable model was developed in the Chisinau children’s club “Firefly” under the leadership of Alexander Pavlovich Marchenko.
The sounding rocket “Dragon III” — two-step. The engines of both stages is solid. The mass of the fuel engine of the first stage (start) — 686 kg. the rocket Starts with the ramp installation. Eight aerodynamic stabilizers (four for each stage) provide stable flight. Measuring apparatus weighing 30-90 kg is placed in the head part. Missile launch weight — 1184 kg. Maximum altitude: 7000 m. the flight Time is 440 C. length of the rocket varies depending on the mass of the apparatus and is of 6.99—8,16 m.
Large problems sometimes arise because of the small details. Take, for example, the servo-mechanism, reduces the efforts on arms control such a powerful and popular tractors as Chelyabinsk Т100МЗ or T-130. They have the bushing hole (see figure), is pressed into the housing of the servo-mechanism, performs reciprocating movement of the pusher, the transmitting motion of the control lever rotate the spool getorcreatenode site. On the pushrod and is an ill-fated piece is a small rubber ring that provides a reliable seal between the follower and the walls of the sleeve.
In the literature on model airplanes is not so much focus on radio-controlled models of seaplanes, although, in practice, many enthusiasts prefer them purely “land”, considering the “waterfowl” more interesting for manufacturing and piloting. Many of them also refer to the usability of such models compared to those that are equipped with wheel chassis, because “land” is not everywhere possible to find a large enough area with asphalt or concrete path for takeoff and landing. While any aquadrome — a pond, lake or river to find not so difficult. In addition, experts argue that take-off and landing in the water are not in the example easier.
Instead of installing switches ship modelers often put on the deck bare conductors or put the bulky switches. Naturally, these alien items spoil the appearance of the model. At the station of young technicians of the city of Sochi for many years put on an improvised model of the microswitches (see figure), Tali. Then put the spring and install the bracket-holder. The deck clip is fastened with copper rivets. The switch is ready. Connecting the wires, you can test the reliability of his work.
A large variety of schemes and designs of radio controlled raketoplana can be divided into three groups. The first is a classic, airborne with the Elevator control and ailerons. The second scheme, a “frame”. The third aircraft with a V-shaped stabilizer. Of the above schemes interesting is the design of the model rocket glider class Ѕ8Т/R Englishman Michael Francesa, made on a frame with an inverted V-shaped stabilizer, this is due to the lower engine. This design of the tail helps to protect it from fire plume when working MRD. Will tell about this rocket plane more.
This question, unfortunately, was the last in the life of a motorcyclist attempting a match to light the dark failure of the fuel…
