Yesterday I made a comparison between the Tamiya TRF421, the Associated TC8 and the TT-02 SRX.
The SRX was extremly close to the high end cars, but the lap times with these were a tenth faster and a little
more consistent.
Not bad looking at the price difference...

By the way, all three were equipped with the same body (BD Eptron), motors, tires, batteries...
