RC-Monster Forums - View Single Post - Planning Revo V2, to use stock tranny, C. diff and RCM motor mount

Sounds like a plan! Do you still want the two speed tranny? Because unless you lock it, it will still shift. You could adjust the shift point until it is basically locked into first or second, but not as solid IMO. As a plus, if you remove first gear, it lightens up the tranny a little, and if you decide to later use reverse and/or motor braking, the tranny will be already capable of it.

The stock tranny is pretty tough and can stand up to BL quite well. The only thing I have broken is one of the little pins securing a gear to the shaft (the intermediate gear in front of second gear).

The end of an XL can does clear the arms, but you'll have to orient the motor so the wires will clear. If you look at my revo pics ("My BL Conversions" link in my sig), you can see how my wires sit. I also mounted a little L bracket to support the wires coming out of the motor. It was mounted using the same screw that holds the rear rocker arm in place, so no big deal there.

If you go with a center diff, you are going to want some pretty thick fluid. I don't know what weight is currently in mine (it's a custom 8th scale diff I got from Squee) but it diffs out easily. I'm thinking somewhere around 300-500k.
