Couple of Questions....

I have a bunch of parts from my nitro revo, almost enough to start working on a E-revo. Here are some questions that I have that would help with a budget E-revo build:

1. From the E-maxx I need the motor plate & tranny correct?
2. Can you mount the steering servo and throttle servo's in the stock location (for the two steering servo's) on the Revo chassis?
3. I am thinking about going with the stock ESC out of the E-maxx and putting two of the new 550 12T Titan motors that come stock in the new rustler and stampede. Will the ESC hold up? What gearing would you put with the motor setup?
4. I am going to mount my batteries similar to the way Dafni did his but the question is where can you mount the ESC & Reciever?
5. Can you use a battery pack from a Revo to run the truck? Where would you mount it?
6. What slipper clutch would I have to use?
7. Is there anything else that I am forgetting?
