Hi, I bought a used Tekin RX8 and Tekin motor R8 1900. . Ran it 2 laps on the track and it stopped running.. When I pull the throttle all the leds lite up across and if I hold the throttle all the leds start flashing. I tried calibrating speed controller to radio but won`t work . Their`s no chimes either . Tried to do factory reset and no luck . I have a new airtronics receiver in the car and servo works fine. Motor wont run but leds ramp up like it sould work. HELP. tHANKS PETE. PS worked good for 2 laps
