Maxx Help needed

[Dafni]

I have the RD-Racing ones on my revo, they are the real deal.
Maybe I should try to get them for this guys maxx... I use sliders on my revo, wonder how the 8mm axle thing work with the cvds this guy is running ATM.... need to get the axles and hex-hubs as well I guess. Or is there another solution for axles to use with the RD knucks?? Or just use 6mm bearings and his existing MIP cvds?? What wud you do?
