In the “M-K” No. 4 in 1983 was about a cord of car-class copies of “rally”, developed under the direction of E. Voronin. The design proved so simple and reliable that are built on published drawings of a micro-Skoda is not the first time, always steadily showing high results. I especially want to mention the original and again is extremely simple in scheme and execution of the automatic control (hold set) speed.
At competitions, we have to marvel at the fact that many refused to use this machine solely because of it’s simplicity! Reasoning, the opponents have established classic carbureted regulators and… were losing our members! But simplicity is not always synonymous with “childish” approach to the problem. This is often a sign of a truly engineering solutions!
On the basis of micro-Skoda designed and built a new model of “rally”. This is a copy of double passenger car Lancia Beta, Scorpion. The three-year operation of the previous microcosm allowed to improve some of the nodes. Such improvements — today’s story.
In contrast to the “Skoda” copy “Scorpion” from the very beginning was conceived of the permissible maximum mass up to 2 kg. Heavy model made it possible to achieve more stable speed and, most importantly, to improve the reliability of adhesion of the rubber of the wheels with the track. The last factor determines the slippage and hence the accuracy of holding the set speed.
The aluminum edges on the longitudinal side members of the chassis frame was replaced with steel, and used the standard profiles corners of 20X20 mm.
