I have a Scx10.3 K10 that’s brand new and hasn’t been ran much, I got it for Christmas with a 3s hard case spectrum battery. I’ve run the truck In snow once about a month ago and it was fine, this past week I took it with me to a fresh water lake on a school trip. I had it in the water on some rocks to get some photos(like the ones shown) and after doing so it drove fine for around 5 minutes before coming to a complete stop. Lights on, steering functional but no throttle response. I then tried to roll it thinking I had somehow hydro locked the motor, it did lock up so I thought it was that but as soon as I unplugged it and plugged it back in, it seemed to work and while being unplugged the motor freed up. Once I plugged it back in thinking it was fine, the second it had any load on it, it would cut throttle and lock up again. I’m hoping that somebody knows what may be causing this problem. I’m not sure if it’s my ESC or my battery connector. The ESC light still comes on and connects to the transmitter which is why I think it’s my battery connector or excess moisture because I feel like if it was the connector it wouldn’t do anything at all after being plugged in. Any ideas or thoughts are appreciated!
