This is the latest on my build. I took it out for some speed runs and made some modifications. I put in some thicker center diff fluid and I still am not happy (frontend "diffs out" no matter what I do), so I am going to install the solid center shaft with a 51T spur. You were right Brian...I actually ordered the parts today. When I switch the diff out, I will also clean up the steering servo bracket as suggested!
I installed my HPI D-Box drift assist and it really seemed to help keep it steady on the high speed straight aways.
I also installed one of Mike's new battery trays...it just lined up better and provided more "opportunities" to bolt it down more securely--particularly towards the center of the chassis. Everything seems more solid now and there is less chassis flex.
Lastly...I put my amateur paint skills to work and painted the stock shell. Eventually, I'd still like to have a better/thicker shell painted by somebody who actually specializes in that sort of thing. After painting this monster, I have truly grown to appreciate the amount of work and effort that goes into the whole masking, painting, cutting, and sanding process.
