This is the third weekend that this has happened: I run an X-ray t2r car with an LRP x-12 17.5. After a couple of runs with the motor coming off the track at 170-180 degrees, the R/S will not turn over the motor when the rotor is in a certain position. If you are familiar with Lrp motors they have strong magnet that keeps the motor from free Wheeling like a Duo. There are five settings or "notches" if you will that the rotor rests on. In two of the five positions When the throttle is pulled on the transmitter the speedo lights up like normal but the motor will not turn without a push.I have tried this speedo with a different LRP motor and a Duo 2 motor no difference, I have tried six different sensor wires and two different receivers.
