get a ubec, or pull straight batt power for the steering servo if you are running 7.4v. The high torque servo is propably pulling more amps than the sidewinder internal bec can provide. A good way to know if this is the problem is to hook a voltmeter to the red/black wires going to the steering servo and watch the voltage when the problem happens. The voltage should not get below 5v. You can use a pair of paper clips to "back probe" (stick in the connector while it's plugged in), just be real careful not to short the paper clips togeather :)
