Eventually I would like to use 1/8 diffs but $$ is the enemy right now. As you see it I have about $1400 tied up. Looks like soon to be $2k. lol I am going to get a battery tray kit and a piece of CF to make a new upper chassis deck. I thought about using 1/8 buggy style braces but dont have access to a CNC or mill. So CF is what will be used. I have had NO problems yet with the f/r diffs. THey are the new Emaxx sealed diffs I dont know what model they come from. THe problem with getting bulks that arent for traxxas is the rig will be down even longer due to more $$ being spent. I like to play. I have other rigs but honestly they get quite boring after playing with this thing
