New E-Revo - first impressions

[E-Revonut]

the diff ratio is the same as the revo/3905 MAXX. But looking at my book that came with E-REVO with the exploded views and part listings it says the input gear is 18 and the output gear is 33. So I have proven myself wrong! I know it has been discussed in another thread but could the increased speed be the mmm instead of mm? That is the only thing I have changed going from my 3905 to e-revo. I pulled everything from the maxx, sold it and put it on revo but used mmm instead. 3905 I was running 62/20 for decent speed. Same motor, batteries,pinion, and even ran talons on 3905.
