Brian,
Can you add the Mugen MBX6e into the calculator? Diff ratio is 44/13. Thanks man! Center dif spur gear is 44T or 46T both sizes come with the kit.
Also, can you add the Losi SCTE? Same dif ratio as the Ten-T but just making it easier to find is all. Center dif has a 40T mod1 gear on it. I also didnt see the RCM 52T 32 pitch Ten-T gear on the list.
BTW. Every time I use your site I'm always amazed at how much useful info there is there!! Keep up the great work!!.
