I just picked up a new z-car (bit clone) and most of the time when I drive it around the house, it is just fine. But sometimes it starts to "stutter". As in, it will keep keep turning on and off in rapid succession.
The z-cars have an LED In them, and when I am driving, it with keep flickin on and off. (It only turns on when the forward or revers buttons are pressed) and the car "stutters" and stops. If I get closer to it, or turn my controller slightly, it will start to move just fine again.
What is the most likely problem? Interference? I make sure all the parts within the car are secure. And help is much appreciated.
