Need help with 1st BL setup in Emaxx!!

Hey guys, I'm new to the forums.

OK, first, I got a sweet Emaxx roller off ebay recently. It needs only a tranny, and electronics and motor of course.

Without a doubt in my mind I want to go brushless. I already have a BL Rustler with a mm5700, and use four 6cell, and two 7cell nimh packs with it.

SO basically I need some help gathering up EVERY part I need for my Emaxx to become RTR right out of the first shipment box. I have had it sitting in my room now for too long, and I wouldn't want to order some stuff, wait 2 weeks to get it, just to realize I need to order more parts and wait another 2 weeks... ya know what I mean!

Ok, I think for now I am going to use my MM ESC from my rustler, and use the same battery packs (12cell, and 14 cell setups for the emaxx). ALso, I am going to buy a tranny from ebay w/ the blue dual motor mount and stock spur gear (not sure what it is).

So would this be a good setup?? Im looking for a relatively low priced setup, but one that would keep up with Tmaxx 3.3's and that would wheelie on command:

Feigao 8XL Motor
RC Monster Heatsink XL size
5mm bore 32 pitch pinion gears (what one for stock spur???)
STeel Idler

ANd Maybe:
SIngle Speed Conversion
Single motor mount
(I say maybe because both seem really pricey for just a piece of metal)

A few Q's
1. Will the feigao motor be able to mount to the stock motor mount or the G1 single motor mount - with the heatsink attatched?
2. Will the stock spur gear hold up very long to the power of the BL motor?
3. WHat gearing is recommended?

I've been doing research for weeks now about all this but I am still kinda sketchy about everything and really want to get the right setup!

Thanks
