Tons of spares and upgrades for the TT S2 available, and will probably continue as the S2 is still the RTR kit from TT....
Its a good car and runs well, the motor is powerful, probably not quite as good as a Hyper7 but still a worthy buggy...
Whichever RTR you buy if you want to race it be prepared to rebuild the shocks and diffs with better (read correct) oils
