So i have a 510R in both of my buggies, the one in my 2wd car acts very strange sometimes. When i hit the power button it powers up immediately but I won’t have throttle, at all. Sometimes for a minute or even more, and then it will start working, and it WON’T stop working correctly after a heavy crash or anything, it keeps on truckin like usual once it decides to give me throttle. Then when i go to turn the power off sometimes nothing happens no matter how many times i try, i will have to literally disconnect the battery for it to shut down, anybody ever have any strange issues like this?

What, if any, color lights are blinking on the speed control when it is doing this?

That happens to any esc if the neutral trim isn't exactly how it was when the esc was calibrated. Set the throttle/brake trim to 0 your EPAs to 100/100% and recalibrate the ESC. That'll probably solve it.

thanks, this one was used. I figured i would do a reset on it and see what happens
