Well I had mine for three weeks and it is a blast mini to drive ..
this 4wd mini is stupid fast with standard tires and I am killing the 21.5 TC ..no one couldn't believe how fast this mini is and drive like the 1/10 scale TC
Full Tamiya mini hop up M08 or any of them , it is cheaper to buy Serpent mini for less
think about it three wheel base setting .three motor mount position ,three drive train set ( Fwd.Rwd.4wd)
Kinda surprised it allowed in 21.5TC
I’d like to race my Xpress even just once
