COMMENTS: S9451 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. 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.

This digital servo cannot be used with the following * AM * transmitters as the servo neutral signal is: 1310us). CONQUEST AM, FG Series (T4FG, T5FGK,T6FG, T6FGK, T7FGK), New Terratop, T3EGX, T3PGE, T2NL, T2LGX, T2FR, T2PK series.

For full performance of digital servos, please use them only with FM, PCM, and HRS systems. Do not use digital servos with AM systems.
