The operating concept is well suited to children, robust enough to even minor accidents to survive the elements without any problems. The tires are not very successful, because they especially on slippery surfaces. While reversing drive in curves have no grip. Say drive works only partially, because you never know how the tires behave precisely. In addition, the vehicle is thus a bit noisy. Nett is one more way the idle position between the worm and donkeys to align so that the 'idle' works reliably. So the smaller kids could also between time with the hands play on the car. Surely this is not the main goal of a remote-controlled cars, hence no deduction for it.
