E REVO Questions and concers!

I have been out of the RC hobby for a year or two now and am thinking of dropping well over a grand on a truck, i have done my research on the E Revo brushless edition but there are still alot of questions i have that arent answered anywhere else. so ya this is a list of what im wondering, and also just a general FAQ thread :)

1. What size are the hex's on a stock E Revo Brushless edition?
2. What is the actual scale of the E Revo brushless edition? (lets just call it the ERV BL from now on)
3. Best shock oil weight?

Thats about all that i can remember off the top of my head, if theres anything else i wanna know ill be sure to either reply or edit this post :)

Any info helps!

1/10 but it sits so wide that people call it 1/8th
