I needed this cause I got a little confused thank you from America🇺🇸

For me the 4 switched on in the beginnind and motors were working. But it was not moving forward. I picked it up to check what is wrong, now only the bottom 2 leds are worrking. Remaining lights and motors are not working. Wheels are not turning. What should i do?

mine works but the track on the back of the paper is too small, try putting electrical tape on a counter or larger surface with larger diameter curves

I think my ic might be damaged, because my leds just stay on solid and car goes in a straight line without stopping. Bummer.
