I tried two freshly charged batteries, and had no throttle. Just a blinking red LED on the ESC at first. I checked all my tx settings, checked throttle signal, checked wiring, checked ESC settings..all good. Eventually, the blinking went away and I just had a solid red LED on the ESC. After that, I found that the motor would run, seemingly fine, until I let off the throttle and let it stop. At this point, there would be no LED lit on the ESC. Then when I pulled the trigger, it would not run the motor again and the solid red LED came back on. I was able to 'push start' the car, then it would run fine again.

This was pretty repeatable. Push start, run fine, stop, no throttle response. Push start, and repeat. This was all with a Tacon 2000kv 1/8 motor by the way, in an RC8.2e with stock spur and 18t pinion. After the first run, the motor and ESC temps were reasonable...I forgot my temp gun at home but I could easily hold my fingers on either indefinitely. When I got home, I tried a Castle motor to see if the problem would persist, and it did. So the problem is definitely with the ESC I think.

Any ideas? If it's bad, what's the best way to get it replaced?
