I’m getting started again with the hobby so only have a few cars, all less than 6 weeks old. My ‘best’ car is a BMW C3782 great speed, stability - hard to crash. I put digital chips in all 4 of my cars. 3 of these cars work well. The BMW (my best car on my analog set up) shot forward, caused a short, slight burning smell and then stopped. Chip fried, tested in the other cars. Braids replaced just in case. I can see nothing visibly wrong when I look in the body (but of course I don’t really know what I’m looking for!). So hoping it was a faulty chip, tried another chip. Same issue. I think I got it off the track in time but don’t want to even try it again just in case. I don’t want to lose this car as it will make a fab Pace Car. Any help/guidance appreciated.
