I hope they hold up, they are the msr8's. The lhs rrecommend them. I said I want something a little beefier than the traxxas big bores. Looks like I'm way low on the diff fluid! I'll probably run it next weekend then open it up and drain it. All of my parts will be here by then hopefully so I can assemble it. Is there any way to post pics without links? Also what do you guys recommend for gearing? I'm gunna get the rr slipper because I liked it on my revo. Probably 60t spur. Are the flm hybrid diffs the same ratio as stock?
