It's a 1:24 scale R/C drift car, This is 4WD (not 2WD) before it was 4.8 volts, I tuned up to 8.4 volts, added 3 more AA 1.2v rechargeable battery.
And speed is nearly 35 kph, But acceleration is really fast with rabber tire, And plastic tire is for drifting (even it's much much faster than Sonic R/C car)
I think this is incomplete tune up! Because i don't have Brushless motor.
