Design

Snow scooter we recommend that you do, will give the opportunity not only to descend from the snowy mountains, but to engage in the slalom. To build it is not too difficult. Well, of course, if you manage to use the weld, but in a pinch you can do without it, replacing the weld bolt.

Do not consider it shameful to use a good development designers and lovers they share the magazine. But, armed with their interesting ideas and technical solutions, and the very creative approach. So for the treatment of potato between the rows was made cultivator-Hiller. He arranged for motorcycle scheme, when working on (cultivator or Hiller) is located between the two running “in the tracks” wheels: guide (“sulker” from children’s pedal cars) and leading (of the scooter Tulitsa).

the Conversation today will focus on the sailboat of a new type — light weight, affordable and versatile vessel-trimaran, which portable travel paddle with a soft shell. The merits of such a lot of trimarans, and one of the most important is the low cost of the kayaks and additional sailing arms. In addition, such a vessel do not require hospital car Park on the shore — enough and the mezzanine in the apartment; to deliver the same trimaran to the water is possible even on public transport, not to mention the train.

Kayak in the open sea… Not even if is”? Well, it depends on what kind of kayak. “Petrel were” — the lightest boat, the description of which is offered to your attention, is not afraid of windswept expanse or sea waves. The survivability of the ship is ensured by its design. Add to this the accuracy on the course and the safety for crew and cargo in extreme weather conditions. In spite of the elongated body, the boat easily, as sailors say, “clears” from the wave, and has a good “viable” even in cool water shafts. All control systems work quickly and reliably, and steering is effective in any maneuver.

With all its advantages of an inflatable boat of any design has the same General disadvantages: Shorty wislica, turtle speed and bad handling. From all of them at once we managed to get rid of, adapting your boat “Dive-4” under sail: with him she became and the faster and more manageable. And actually upgrading was quite simple and compact, that is blended with the amenities characteristic of inflatable boats.

Wheeled Buer, beach sailing, sand yacht, metromobile… All these terms refer to the same Tina of vehicles using the movement force of the wind. Designs of such “petroholod” — a great many, from year to year are added up — three wheels and four, with Latin sail and with the Bermuda arms, hard planes, reminiscent of an aircraft wing, and even with a horizontally positioned fan-like impeller anemometer.

No matter how much we have seen this picture every time it will amaze and fascinate with their uniqueness: easy flick of a switch — and just as silently as it stood, the car started and ran, picking up speed. The heart of this design — the electric motor. To it again drawn the attention of automakers and even in connection with energy problems. Do not stand aside from these searches, and Amateur designers, some of their works have been highlighted on the pages of our magazine. Today we introduce the electric car of formula D — baby, built by our reader A. Logvina from the city for his daughter called “Alyonushka”.

I’m a physics teacher and a faithful subscriber of the journal “modelist-Konstruktor”. Write and assemble a binder began while still a student in 1980. Thanks to him I became one of those whom the people called “avid homebrew”. One of my first designs was a mini-tractor “Gerez”, built together with the guys from the circle of technical creativity, which was led by part-time. Mini tractor took first place in the Republican review of technical creativity of pupils. Engine — motorized С3Д installed across; the gearbox from the car GAZ — 51, rear axle — from “UAZ”, shortened. At the mini-tractor 20 gears: 16 forward and 4 backward speed from 1 to 52 km/h. Its own mass of 500 kg can pull the truck with load up to 1200 kg.
