Product presentation
This is the Futaba S9254 Digital Coreless High Torque, High Speed Helicopter Gyro Servo with J Connector.
This servo can produce high-current draw from your batteries. If using NiMH or LiPo batteries, make sure they are
capable of delivering sufficient amps.

Comments
S9254 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-oF 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.
A note on Coreless motors. A conventional servo motor has 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 servo is rated as high-torque for helicopter gyro applications; the rating would not be considered high-torque for
airplane control surface or monster truck steering applications.
This digital servo cannot be used with the following * AM * transmitters as the servo neutral signal is : 1310us.
