I'll need to have another look tonight, the cable to the receiver and the plug look ok, I'm unsure if I want to cut and rejoin the wire to the receive incase it doesn't make any difference, but I guess I might need to if everything else fails. Just don't know why all of a sudden changing motors has disturbed the wire to the receiver ?
When I refitted the vortex motor, it powered up fine and worked with the car held off the ground, then I turned it off, and back on again about 5 mins later to start my race, and thats when I have no lights and no throttle.
