Radio Delta

RC hang-glider model for beginner aeromodellers

This very “flyable” radio-controlled powered hang-glider model was designed specifically for beginners: it is not difficult to build, and it is practically impossible to wreck on landing. A wide variety of materials can be used to make the model — from balsa to basswood (linden). For the formers, even ordinary packaging foam will do, for Read more…

Motor plow

Homemade V. Petrunya motor plow: drawings and guide

Isn’t it a striking contrast: while the fields of collective and state farms are cultivated today by powerful “Kirovets” tractors, the household plots of rural workers are still plowed the old way — in the best case with a horse-drawn plow, and in the worst simply dug up with a shovel. This work is unproductive, Read more…

Tracer potato planter

DIY potato tracer and planter made from pipes

Potatoes are often called the second bread, emphasizing the extraordinary importance of this crop. Yet in terms of labor intensity, especially on individual plots, it is far from last on the list. All the more so if all the work is done here the old-fashioned way, without any means of mechanization. A device I designed Read more…

Mini galley for a boat

Mini-galley in the Triton cabin: folding table and sink

On small cabin boats and yachts, every square decimeter of space counts. Finding a dedicated place for a galley is a problem. So to cook meals you have to moor to shore each time, and the crew has to settle right on the grass and ants. On top of that, you have to carry dishes Read more…

From road bike to touring bike

Bicycle bags DIY: frame kangaroo bag and repair kit pouch

I rode the Kharkiv Bicycle Factory’s “Tourist” bicycle for 30 years. It was, perhaps, one of the best Soviet bicycles — not only for active recreation (which it was actually designed for), but also for everyday trips. Now it hangs on the shed wall as a retro exhibit. Instead, I bought a new, modern two-wheel Read more…

Half a meter of health

Sports corner for a small one-room apartment

Undoubtedly, a home sports complex is necessary for any family, especially a young one. But what if you live in a small one-room apartment or, like my family, in a dormitory room? Under such conditions, when you cannot even install a basic pull-up bar in a doorway, talking about a full gym is simply unrealistic. Read more…

Build-it-yourself chair

Knock-down plywood chair with interlocking grooves

When making furniture at home, the main problem always arises for the amateur craftsman: how to join the individual parts, what fastening to choose so that it is simple but reliable. Everything is used: from simple nails and screws to mortise-and-tenon and complex glued joints, bolt fastenings, metal parts, and shaped profiles — depending on Read more…

Motorboat “Lada-75”

Lada motorboat: MK design with a sea-knife hull

Thousands of motorboats and launches built by amateurs to designs from the MK design bureau ply the waters of rivers, lakes, and even seas across our vast homeland. These include the widely popular Moskichka, Volzhanka, Strelka, Rusalka, Taifun, and Ruslan. An experienced specialist will recognize them at once by their characteristic profile and attitude on Read more…

Ping-pong on the lawn

DIY folding table tennis table for yard and garden

Homemade table tennis tables in a yard are usually made stationary: crude ones, from boards or even from concrete slabs — such structures can be called a table only conditionally. And they are not protected from precipitation, constantly remaining in the open air. Imported folding tables have now appeared on sale; they “break” in the Read more…

Got a hole? We’ll fix it!

How to repair a windsurf board hole: step-by-step patch

One cannot help but admire the swift glide of a windsurfer catching the wind across the water, or the no less dizzying descent down a cresting ocean wave on another board resembling a wide ski. Both of these sports craft, under a fairly thin outer shell, have a fairly soft foam filling, so damaging such Read more…
