Savage Brushless Conversion Dilemma

I think i just going to go with the flux setup. I'm just going to get all the stuff thzero said above other than the bulletproof diffs because I am only going to be running 4s. I am going to start ordering the parts asap and get this project going. Here is a list of everything I am going to probably get:

GCM Motor Mount

TCS Flux Chassis or TSC Flux XL Chassis

Flux Battery Boxes

HD Drive Gear

Flux Tranny

Motor Plate

Motor Brace

Battery Box Mounts

I don't feel like totaling it up because I am too lazy
