lol, the calc is pretty accurate for the most part. The user on the other hand...
Also, was working on figuring the ratios for the new emaxx (3905) tranny. It seems that the two-speed setup is a little more involved than the original; first gear has two actual ratios, while second only has one ratio. The Savage tranny kinda works the same way (somewhat), so I'm gonna do some code changes to allow multiple ratios in the tranny drop-down for these types of vehicles. Until the code is updated, here is a quick-n-dirty diagram showing the placement of the gears and the ratios:
Single speed (stock) and Two-speed second gear ratio = 1.83:1
Two-speed close-ratio first gear ratio = 2.96:1
Two-speed wide-ratio first gear ratio = 5.08:1
