The stock speed controller TBLE-02S in my TT-02 seems to be working, but it would sometimes seems to be having issue. When I punch the throttle hard, the car would accelerate for a second then stop as if the battery is completely drained. Then after another second or two it would resume power. I've made sure the battery is fully charged, and this still happens sometimes. When I don't punch the throttle like this, it usually doesn't have a problem. This happens with the stock brushed motor. I've ran another brushed motor and still same issue, so I don't think it's my motor. I did set up the ESC per the instruction ... Anyone else ever experienced this? It's a really annoying glitch whenever it happens.
