S3155 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,minimizing lead lengths, and/or removing Y-harnesses.
Current Drain: This Digital Servo is specially designed for high- torque or high-speed, therefore very high current drain is normal at startup.
For ultimate performance when using this servo please review the following points.
1. Radio systems with the Battery Fail Safe function have 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 motor and battery life.
