Just built up a brand new kit.... the diffs and drivelines are buttery smooth but you have to shim correctly. Unfortunately manuals don't contain many words anymore, just exploded diagrams. I just have to shake my head on this one... it's not rocket science, but a few words to go along with the diagrams would save so much time! I still have the manual to my Associated RC10GT I built back in 1994 and it's perfect! I never thought I'd ever say it, but man, they don't make 'em like they used to...
Anyway, on my front/rear diffs, I used shims next to the black metal spacer ring over the pinion carrier and this allowed both bearings to fully seat in the diff cases and there was absolutely no binding; they rotated extremely smooth with no play front to back. And no, my manual wasn't updated to reflect the absence of shims inside the diff housing, nor were the 2.5mm button screws provided - they give us phillips wood screws instead - cool. There was a one page addendum sheet but it didn't illustrate the absence of the smallest shims in the case. But the good news is that I did receive the wrong size bearings for the center diff.... so much for getting past step 1! Getting the diffs built right were a phenomenal PITA because of the lack of updated documentation and explanation on shim placement and requirement.
Beyond that, there really weren't any significant issues. I purchased all steel locknuts instead of using the plastic ones included and I got an aluminum servo arm. This thing is pretty nice overall once you get the nuances figured out. They include a mix of industrial bearings and basic sealed bearings - I see a full Acer Ceramic upgrade in the near future. I can't wait to install the electronics and try it out. I know it's gonna be solid here on out.

I am installing a RX8 to my Serpent BE. Three questions.... Does anyone attach the ESC to the radio tray via screws? If so, what size are the screws? What does everyone use to put under the ESC to mount it and protect it? I have velcro, but I think there is a better solution somewhere....

Thanks for the pics, sure does make the car look better. Those big battery doors are functional, but bulky looking. Did you use anything to take up the gap between the batteries and straps? Some batteries are a little thinner and need some gap filling to keep the batteries from moving up and down. Easy fix though.

Jkoiva (or others),
Do you have the current limiter set on your RX8? I just built up an 811be 2.0 and installed an RX8 and T8 2050Kv. I have my limiter set at 90% but was curious as to if I could run with it off. I've only just finished and run it up and down the street a few times. I haven't even discharged the packs yet.

. I'd drop it down to 75 or so to start off with and go up or down as needed.
