COMMENTS: S9155 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: 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 life of the motor and      
         A note on Coreless motors: conventional servo motors have a steel     
           core armature wrapped with wire that spins inside the magnets. In   
           a Coreless design, the armature uses a thin wire mesh that forms a  
           cup that spins around the outside of the magnet eliminating the     
           heavy steel core. This design results in smoother operation and     
           faster response time.                                               
         This digital servo cannot be used with any AM transmitters including  
           the following Futaba models as the servo neutral signal is: 1310us.
