OK so few more upgrades:
Quick Charger:
This is kind of disappointing, it doesn't come with an outlet plug so you either have to buy / make one or charge it in your car....
1400MAh Battery Upgrade
I haven't run this in a fully built car yet but I did test plug them in and turn it on, on my desk to test my rear diff and they ripped the car plus a whole heap of stuff straight off so they seem pretty potent.
Now for a whole bunch of photos focusing on the rear diff, the RC18T dog bones and the Super MIPs.
This is stock vs. Super MIP:
Super MIP is the bottom one.
RC18T Dog Bones with stock rear diff.
Missing front gears...
Super MIPs with RC18T dog bones.... it can be done.....
