hey hey… I happen to have both of these two, they are bothlight up cars(headlight, taillight… HG refers to the high-grade leds i think maybe?), the difference you arenoy mentioningis either lights or fornt wheels turning left or right. (this does NOT effect steering in the slightest, as the front wheels are plastic, not rubber, andthere are two motors in these things, one in each rear wheel, and it steers like a tank ie. to turn left, the left wheel will spin slower than the right…) I dont mind these little cars, bought em both from Japan a while ago. They are slow to charge (about 20 mins), runtime is approx 15 mins (???), and my main gripe, if the IR unit on the controller is not pointing straight at the car, it aint gonna go so good. Add to this the fact that they don’t work in direct sunlight (so no outdoors at all), theycannot be hopped up,and they are hard to turn at times (at speed; i’ll get to that!!). Upsides; they havee two speeds (fast and holy s**t!!!), detail is incredible for something thats less than the length of a Bit Char-G, but the ‘super deformed’ styling might put some off. Quality of unit, car and even packaging is A1, but you will need an english version of the instructions, unless you know someone (or you yourself are) fluent in Japanese! All up, enjoy. These things are great,I just need to find someone who’ll do a battery swap in mine, I cant bring myslf to open them up!
