S9351 Digital Servo Precautions, -It is best to avoid long leads and Y-harnesses especially with standard grade wires. If problems are encountered, consider using heavy duty wire such as Futaba's Heavy Duty Series or Hobbico's Pro Series, minimizing lead lengths, and/or removing Y-harnesses. -Current Drain: Futaba S9350 Servo is Specially Designed for High- Torque and High-Speed, Therefore Very High Current Drain Is Normal At Startup. For Ultimate Performance When Using This Servo Please Review The Following Points.
(1) When Using Systems With the Battery Fail Safe Function it Has a Higher Cut-Off Voltage Setting Which Will Cause Shorter Operation Time.
(2) When Installing the Servo Please Check Pushrod Linkage To Make Sure There Is No Binding in Order To Prevent Excessive Power Consumption and Decrease the Life of the Motor and Battery.
