The idler gear has no effect on the ratio in the tranny. Emaxx 2nd gear has an 18t top gear and a 31t bottom gear. The ratio is 1.7222222 = 31/18. Because both gears engage the idler it spins at the same rpm. This is true of any 3 gear tranny. The idler is only used to space out the two gears for packaging reasons.
