    Angry Throttle stops working after pull start

    Hi everybody,
    so I just fixed my truck up (fs racing victory truck nitro) after I hit a pole and it lost control and smashed into the gutter. I broke the battery box and engine mount. Ounce fixed I went to test it out. So... Everything seems fine with the servo full throttle full brack, until I turn the motor on. After I pull start and the car is running the throttle twitches and doesn't hold open it hold full brake fine but when I hold open throttle it only opens and closes slightly I have checked everything and can't think of anything. Any help or ideas. I have an identical truck which I have swapped esc and wires with but can't find an answer

    Have you tried replacing the throttle servo? That it will hold brakes while running but not open the throttle makes me think the servo is messed up. That's where I'd look first.

    Sounds like something is loose causing radio interference. Check engine mount to engine, engine mount to chassis, and anything else that has metal to metal contact that May have been damaged.
    If you are a cyber spacecadet, stop wasting bandwidth and unplug the modem.

    So with the engine not running it all works perfectly... Full throttle and full brake via the remote?

    Does this sound about right
    so if u turn on the radio and car, The servo works as it should, when u pull or push the trigger on the remote the servo moves all the way to full throttle and full brake. then if u start the engine it looses most of its range of motion and only moves a little bit....does it work again if u stop the motor?

    If u have an identical truck that works. U could use that to test the servo and receiver.
    what type of radio are u using?
