My car is really similar to a scooter, because her front end and engine (except for the cylinder 8 of PD) — from the “Vyatka”. All other components and parts taken from motorcycles and agricultural aggregates or manufactured in the home workshop.

IGNITION WITHOUT PEREKREST
The simultaneous launching of multiple model rocket engines presents a great challenge for modelers. Existing methods of ignition have several disadvantages; Perekrest does not allow you to launch multiple missiles for a short time (as the products of combustion clogging the tubes, burn the ends, etc.), as currently practiced method of ignition with the banks is a danger of explosion engines because of the filling of channel MRD pyrotechnic compositions.
MONALISA WITH MOTOR
Last spring I made myself water skiing. But to slip on them could rarely, as the role of the tug performed… a motorcycle with a sidecar. The construction of special boats would require a certain cost, powerful engines, and most importantly – time.

WALKING TRANSPORT

“PAPER JUMBO”
With the end of the Civil war in Russia and the formation of the Soviet Union began intensive development of commercial aviation. July 15, 1923, opened the first regular air line Moscow – Nizhny Novgorod. For three and a half months by air it was transported by 270 people. In the following year there was a line Odessa – Kharkov, Moscow – Kharkov, and others. The development of Civil aviation is objectively required the creation of a passenger aircraft. One of the developers of passenger “air carriers” was the aircraft factory No. 1, former “Dux”, where in 1925, the engineering team headed by H. H. Polikarpov, and A. A. Semenov established a five-plane PM-1.
