If the truck is that heavy, I would say lock it into 2nd, but keep the mechanical brakes. That way you can use the motor for reversing and soft braking, but when you need to stop in a hurry use the mechanical brakes to take the load off of the esc.

Depending on your budget I would say BL was infinately better than brushed, plus you already have all the neccessary upgrades to run BL pretty much.

Good Nimh batteries are perfectly fine, you want some IB4200 matched packs or something similar.

Dont whatever you do buy an E-savage; junk.

The converiosn its is fairly straight forward, you just need a mount for the motor and batteries, and find somewhere to mount the esc, radio and rx pack- Some photos would be great to that end. How much does this thing weigh, that will help determine the motor/ esc choice.
