so i bought a second hand brushless e-revo (the 1/10th one). I think its an older model (it has the TQ remote not the TQi). Apologies if I'm asking something obvious below but I've been reading around for a few hours and no joy.
Anyway, here's the problem. When driving it today, it stopped responding to the remote. I thought it might be the batteries being flat but new batteries made no difference. I've done some troubleshooting and it seems to me like something between the throttle servo and the receiver.
If I turn on the car (without turning on the remote) then the startup beeps play. The light on the ESC is yellow (with a slow flash on the green) and the light on the receiver (link) is red or flashing red.
If I turn on the remote and then the car, I get a bunch of different results. Most of the time I get no startup tone and often I get a red-light on the receiver. Sometimes a flashing a red light on the receiver and sometimes a red and green flashing light on the receiver. Sometimes I can get the wheels to turn in response to the steering on the remote but generally not the throttle. When the throttle does work it seems to only work intermittently and then it stops working. Also sometimes the throttle the flicks on for a split second even through no action is taken on the remote, similarly sometimes the steering moves even though no action on the remote. I can often get the steering to work.
However, if i unplug the throttle servo from the receiver then when I turn the car on I get the startup beeps. Further to that, if i separate the three wires in the throttle servo (orange, red, brown) and plug in any 1 of them on its own then the startup beeps play on startup. If I plug in the orange and brown wires the startup beeps play on startup. If I plug the red wire and either of the other wires with it then no startup beeps. (unless of course the remote is off and then any or all throttle servo wires being plugged in results in the startup beeps playing).
I'm at a loss as to what to try next. Any help would be gratefully received :-)
