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…

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.

In recent issues of our magazine, a series of articles by a group of autogyro designers was published about the features of building these rotary-wing machines, about how to build autogyros, and how to fly them when towed by a boat or an automobile.

Mini tractor made in the Far East

Mini-tractor Amurchonok: design and components

Our magazine has already written more than once about Krasnodar, Stavropol, and Ural tractors, motor plows, rotary rippers, and electric mowers created in clubs by young designers. These machines are a good help both on the school plot, on the experimental plot, and in the field. The mini-tractor “Amurchonok,” described on these pages, was built Read more…
