microbump.
it appears i have cracked the front diff case.. i was hearing squeeking and started to clean the truck up, and i just noticed this:

posing :)





batteries are soldered, and everything's ready to go.. i'm leaving the cracked diff case, for now, because i don't have a spare. hopefully it'll run ok.
