    Angry Help!

    So I bought and built the trx4 kit i ran it like maybe 2 times and the esc smoked and melted apart. So I bought a new one and hooked it all up it worked for the first like hour I used it. Then it just shut off. I put it away and the next day plugged in a fresh battery and my transmitter lit turned on immediately which has never happened and my steering servo was buzzing like it had power to it so I go to turn on the esc and it flashed green and then red like 3 times and them shut off. That's all I can get out of it? Does anyone know what i should do or look into. I wanted to go brushless but I didnt want to buy a whole new set up and then have it burn out because something esle is wrong with the car?

    The brushless or brushed that I know of dependes on how you use your rig. I stayed with brushed. Also call traxxas they replaced my esc and servo and now I them for back ups. Traxxas really takes care of their customers.

    First test is to eliminate a bad servo.
    Unplug the servos.
    test if it start normal... yes plug one servo in at a time until the issue happens again that's the bad servo.
    Did you recalibrate the tx to the esc
    Throttle reverse neutral? After changing esc.

    Something is not right.
    Same issue if you unplug motor?
    Next thing in the chain would be a rx issue.

    Does the tx go solid green or is it flashing?

    So I have an erevo 2.0 with the same radio/transmitter and I unplugged everything from the transmitter and plugged the trx4 esc into it and it came on green like normal. So does that mean I just need a new transmitter/reciever?

    Sounds like rx is bad.email traxxas
    See if they can help you out.
    When the esc went it may have damaged the rx.
