I have an almost year old short course combo and now I've ran into problems after I changed my receiver and radio into Kyosho KT-201 even I think it's unrelated. Receiver and radio IMO works correctly as there are no problems with another car.

The car needed a nudge to start moving. So I checked every possible connection of the wires and started fiddling with the ESC settings. No luck. Then I changed the sensor cable and things started to look bit better. But the best I've now got out from the system is that motor starts about 3/10 times without any help and breaking works but no reverse. Any ideas?

Another question about the leds default behaviour: When I turn ESC on, both red and yellow leds are on, and when on throttle or break/reverse, both leds are off. Is this normal?
