The size of the center gear will not change the ratio as long as the 2 outside gears are the same. So, you could run a 28t 32p gear for the idler gear and that would lower the final output shaft a little.

Scott , Your right till you get to "would lower the final output shaft a little." It dose not matter what size Idler gear as long as the input and output are the same you would not change the ratio . Now If you are referring to changing the out put to a 28 tooth then yes you would lower the ratio. All Idler gears do is keep the output same rotation as the input . But very good Idea as the same for willy ( custom rc models ).
