The discussion around motor specifications in slot car racing is ongoing, particularly when considering different brands and their compatibility. A recent conversation highlighted the use of Pioneer motors and their potential impact on race dynamics, specifically in comparison to Scalextric motors.
One experienced racer, Mick Kerr, suggests that using Pioneer motors shouldn’t pose a problem in races where Scalextric cars are also prevalent. He points out that top-tier Scalextric motors can reach speeds around 21,000 revolutions per minute (RPM). Pioneer cars typically come equipped with a 12-tooth pinion gear, while Scalextric uses an 11-tooth pinion. This difference in gearing implies that the top speed and braking performance should remain reasonably balanced between cars using Pioneer and Scalextric motors. Kerr even welcomes the idea of seeing more Pioneer cars participating in race series, believing that motor compatibility could facilitate this. He also acknowledges the common issue with “Ready-to-Race” (RTR) rules in slot car racing, as manufacturers frequently introduce product upgrades, making consistent specifications challenging to maintain over time.
However, another perspective, shared by Jules, emphasizes the inherent variability in spec motors used in race clubs. While often referred to as “Mabuchi” type motors, these are generally not sourced from the original Japanese Mabuchi supplier by slot car manufacturers. Instead, they are mass-produced in numerous factories across China. These factories prioritize large orders, often in the hundreds of thousands, for diverse applications, with slot car motors representing a minuscule fraction of their total output. Consequently, achieving precise and consistent specifications for slot car motors becomes difficult within this mass-production context. Variations can occur due to factors like machine operator errors during production setup.
To ensure meaningful parity in motor performance, especially when race rules depend on it, Jules proposes a system where each racing season begins with motors directly supplied by the slot car maker. These motors could then be marked and distributed to individual competitors, ensuring a level playing field from the outset. This approach aims to mitigate the inconsistencies inherent in mass-produced motors and provide a fairer racing environment based on driver skill and car setup rather than motor lottery.
