By the time you have brought all the Tamiya Hop-ups you may as well get a top end kit, I have used the TC4 (spent hundreds on wishbones!!) xray T2 great car and easy to set up with the click rebound adjustment on the shocks and my latest the HB cyclone , which I am sticking with, never broke anything on it and its a good neutral handling car!
Belt is better than shaft but you have to keep them clean!
I have a T2 roller for sale if you fancy it???
and its mint used n carpet only!
