Query: DON'T BUY - NO NO NO

POS - I haven't seen a toy manufactured this badly in a long time!!! I never had control of them. They crashed within 10 seconds every time. I know it wasn't defective, because I bought one of each color for my sons (who are now extremely dissapointed!!!) CHEAP CHEAP CHEAP - DON'T DO IT
