Gear Ratio --
Any 2 meshing gears will have a ratio, which refers to how many revolutions the smaller gear spins compared to 1 revolution of the larger gear. This is usually expressed as xx.x : 1 (such as 32.6 : 1). To find the ratio of 2 gears, simply divide the number of teeth on the larger gear by the number of teeth on the smaller gear. The primary drive ratio (pinion / clutchbell and spur) and internal drive ratio (diff / ring gear and output gear) are the 2 most common ratios used in RC.
