    Forward is backwards

    I hadn't used my car for a couple of months. When I turned it on, the motor and wheels ran at full speed in my hand for about 10 seconds without touching the throttle. When it calmed down, and tried to run it, when I throttle forward, it goes backwards, and vice versa. Anyone know the likely problem and fix? I haven't done much tinkering for several years and am a bit rusty, and can't find the necessary instructions.

    Swap any 2 of the 3 wires between ESC & motor. That should fix the forward/reverse problem.

    Thanks. I'm puzzled why it worked fine for several runs over several weeks, then suddenly it's all backwards. I need to look up the ESC guide I think. I lost it somehow.

    I seem to remember that you switched to the 70/30 setting also?

    If it worked before and now it doesn't and nothing was touched I'd try re-calibrating and/or resetting the radio/esc.
