With similar problems they have, for example, to meet when you combine the joystick with the keyboard on the basis of MC КР556РТ1 (КР556РТ2). However, it may be that the existing programmer (even among the so-called universal) are not designed for firmware of these chips.

Currently, however, the situation is changing: in the automotive market began to appear on cars, arranged by type of sports “monsters”.
The Moscow Lenin order aviation Institute named after Sergo Ordzhonikidze at the faculty of aircraft engines has a student design Bureau (SKB-2), which is headed by candidate of technical Sciences, associate Professor V. V. Serdyukov. Great attention is paid to engines of small displacement, which are widely used in various types of modeling. SKB has considerable expertise in designing such engines. Many of them were exhibited at the exhibition of economic achievements and international exhibitions, and their authors are awarded with medals and diplomas. On NTTM-74 was shown a new “Orbit”.
