Phantom Model Sports Next, we ran the car at full speed into the wall of the shop. Smack!, and not a scratch, reversed the car and repeated it many times. Apart from paint falling off, I am impressed! We rolled the car, made jumps and ran it down a flight of stairs. Results - not a bruise. The car was taken to the bitumen and concrete carpark next door. On concrete, the standard tyres did not have much traction due to the amount of dust on the floor. At times, we had to brush and clean the mechanical speed controller to keep the car going. On bitumen, excellent grip, however, the tyres were getting chopped up pretty badly, deep scratches also started to appear under the chassis. This is due to the low ground clearance of this car.
