My article on the so-called separate lubrication system for a two-stroke engine was published in “Modelist-Konstruktor” No. 7, 1991.

The advantage of a paint sprayer is well known: it provides quality coverage. Moreover, achieving smooth transitions from one color or tone to another can only be done by spraying. And for this, you need to have a compressor in your home workshop. It won’t sit idle after apartment renovations either, and will come in Read more…
«Dear editorial board! While reviewing back issues of ‘Modelist-Konstruktor’ from previous years, I became interested in materials about biogas published in issues No. 1’87, 5’88, 4’96 of the magazine.
