I have 6 of these X mods I got these when I was looking for a cheap RC car I could modify.So When Radioshack here in Canada became The Source CC the cars price were cut in half and so were all the mods for them I have a black R34 a Yellow R34 that's now GunMetal a White supra The 65 Mustang NSX and RSXthe Gunmetal R34 has a stage 2 motor metal bearings suspension upgrade AWD and Drift tires but the thing drifts better when I use Soft slicks in front and Hard slicks in the rear (on a hardwood floor).Since owning these little racers I bought two Tamiya TT-01's.They are perfect for running around thae house and having fun on those rainy snowy days that prevent me using my TT-01's.
