Speed Calculator

Ok, I added the diff for the HPI Flux, but am having a little trouble deciphering the tranny. I've attached the PDF excerpt from the manual showing the tranny.

86087 looks like the input gear, but there are two which is common for two-speed trans. Then I see the output shaft with one gear (86098), simple enough. But then I see what I think is the idler shaft with only two gears on it (100905 & 86084). If this is two speed tranny, where is the intermediate gear on the idler shaft (the one that contacts the output gear)? If this is a single speed tranny, where is there a dual input gear and two output gears? It looks like maybe this is a single speed tranny that is set up for future dual speed use. So, until this is cleared up, I'm not going to include the Flux tranny.
