Hello Everyone, I believe ELK has called us already and is sending the system in. If not, you can and we'll get it taken care of. I'm not sure how that could have happened. We run all the motors 3 different times on 3 different testers before they are packaged. I'm stumped.
As for the braking issue. I will take that up with engineering to see what they say. I'm pretty sure the voltage spike from the brakes is damaging the ESC. I've watched these motor run on a "Scope" and they brakes offer a HUGE spike compared to other R/C applications or equipment configuration. Your recommendation for only using brakes on the track is probably a good idea.
You can email me at anytime for Novak or any R/C related question. We're glad to help and give you the correct answers, or at least try to find them.
