Hi guys so far two of my throttle servos have stopped working in my reciever box (duratrax rx301f) i don't know why, i tried putting the steering servo into the plug and it didn't work, so do i need a reciever or is a battery issue altough the batteries were now charged. Any help is appreciated thanks

yes, id try charging the battery to capacity & make sure the voltage is good.

I've had a receiver drop a channel. If the battery is good, it's safe to say the Rx has gone south.

well i tried switching the steering servo into the throttle plug and it worked this time, of course you know when i press throttle the steering would respond so i know the throttle servo has to be gone, but what can cause that, this is the second servo that did that in the throttle plug bad battery voltage, a glitch in the reciever or what.

The likely reason could be that you have not set the end points on your throttle servo correctly using your transmitter this could lead to the servo trying to open/shut the carb more than the carb can actually move, which burns out the servo. I have gone through the same problem.
