    ESC Failure???

    Hello everybody

    Yesterday I ran my mini summit and It worked great. I use a venom 2s battery that is made for 1/16th cars. It is 35c and I had no issues with it. However when i went to run the car, it started to drive and then just randomly shut off. I tried to restart it, I unplugged the battery, shut off the controller and turned it back on, but nothing would work. I really do not know what is causing this. THe esc is the vxl-3m. the car is running a larger pinion and it did get fairly warm, but I could still keep my hand on it for a while. I don't understand what causes this. At first, the green light on the esc turns on and then fades to red and turns completely off kinda like its not getting enough voltage. I don't understand why this has been happening, this is the only rc I have functioning right now and for once I would like to enjoy the hobby without having anything go wrong....


    Thanks, and have a great rest of your day!

    The wires on the inside of the ESC might have a loose solder connection. Do you hard bash your mini summit?

    I would try to disconnect the servo wire from the receiver and then see if it will startup. Broken servos can cause weird ESC behaviour.

    No its just a fried esc. I accidentally left a battery plugged in for a few minutes with the esc turned off. I realized it was plugged in so I un plugged it. I then noticed the esc was extremely hot, even hotter than when I was running it at full throttle. Luckily there are warranties for a reason so I will call traxxas and get a new one

    If it is only plugged in for a few minutes, it should not get to that temperature. Especially when it is off.

    I hope Traxxas will replace it under warranty, but I agree with GreenSpider25 that it should never get hot when you leave a Lipo connected. Not recommended, but it should even be possible to leave it connected for a longer time. Of course both situations with the ESC switched off.

    Esc has arrived, I will put it in today! Hopefully it was just a fluke that won't happen again
