the game of car racing on an analog track, is mainly speed and car control, knowing when to strike in which track, overtaking at the right time. So top speed is one of the keys. Although too fast is no party, each type of track has its own average speed to attac the track as well as possible. digital driving with fuel management and pit stop and lane changer is a completely different experience, where speed is much less important, strategy, track knowledge are of great importance here, it is more as a game of chess,When I did my cars I measured the voltage and compensated for any minor variation. Maybe not necessary with digital?
