To design and manufacture a racing car that would satisfy all the requirements of the sport today — Oh, how difficult! To do this, the athlete has to be both a competent designer, and technologist, and specialist in materials science, and machine operator-universal.
But, anyway, work on any new micromachines starts with a sheet of drawing paper. At this stage it is possible to carefully analyze the layout, to exclude or to neutralize disadvantages of the design.
To help the athletes in the most critical stage of design and designed this publication. Using drawings, you can build a modern cord class E2 or using these materials to try to create your own version.
The machine successfully passed sea trials. Front suspension and rear axle showed reliability in operation and a stopping device functioned flawlessly.
The model designed for serial domestic Microdrive CSTOM 2,5 CU-AC. However, the frame design allows to install other Soviet and foreign motors in this class. The frame is made of duralumin by milling according to the preliminary layout. On the frame with the help of crackers hung the rear axle housing, which is milled from a steel type 40CR. On the axes crackers are deep groove ball bearings 4X11.
Gear ratio 1:1,8125. Gear made integral with the shafts. Material — steel 12 HSA (carburizing and related heat treatment to the hardness after quenching in the range of HRC 60…62). Gear shaft reducer is mounted on two ball bearings 6X19, and the shaft-gear rear axle — bearing 6X15.
The design of the rear and front shock absorbers similar to each other: the steel glass is the bronze piston and the spring, and to mitigate the recoil shock suspension at the bottom of the Cup padded soft rubber.
