I`ve been using a Lehner 4200Basic motor/7018warrior esc in my touring car for a while. The motor isn`t that fast(compared to 12T), and the controller is a bit unstable(losing brakes/reverse). Other than that it works well

Black-knight: Miniman is right rumrunner is your best bet here in the U.S.
Miniman: I have a 5300 Lehner with the same ESC. Do you experience cogging (jerky movement) from a dead stop? I have to run a separate battery receiver or else it would even hardly move from a stand still. I spoke with rumrunner and they instructed me to use the batt. receiver. This car has a lot of power and top speed and I already tried gearing highs and lows. As long as it is at a rolling state, it's fine. Sometimes, when I start decelerating it will unexpectedly brake by itself quickly, it feels like a glitch.
A friend of mine also has a lehner 5300 and a Schultz ESC and it's smooth as hickory.
Any comments is appreciated.
