Well at this point I've patched the buggy togeather so that I could run it just to test the electronics. I found that the Savox ultra speed servo pulled way to much current from the MMM BEC circuit resulting in shut downs. So I grabbed my CC BEC and wired it in (still need to shrink wrap it again) to power just the servo. Works like a charm, this servo is really impressive on 6 volts with enough amperage to feed the beast.
I'm still planning on flipping the motor around and locating the CD at the back of the buggy but untill the RCM universal diff/motor mounts are back in stock it'll be in this layout. I think the steering servo can remain in it's location from here on out.
I hope the lipos will show up tomarrow (day #7 of USPS 1-3 day priority mail) so that I can start mounting the trays and experience this rig on 4S. I did my testing with a 2S maxcrapp that was salvaged from a 3S pack (4 months old and they wouldn't warantee it because I cut it open to isolate the bad cell and save the rest of the pack...)
So far I like the layout with all the stuff centered in the chassis, the motor is high above the chassis plate but I think it's a good compromise to be able to run a pair of large lipo's for power and run time. Can't wait to get the lipo's installed and running.
Here's a pic of what it should look like with the trays installed.
