Still curious about high voltage to a S3004. I operate them at 6.6v ok but 7.4.....
Great point!!! The servos have to be high voltage rated if you are going over 6 volts (6.x). So, I would look there first. If the OP is running 7.4V and all his radio is set up for high voltage except the throttle servo, that is where it will fail. The Rx can handle the higher voltage, but the servos are the limiting factor.
