- Power Supply: 4.8V (Futaba does not recommend using 6V)
- Length: 1.6 x 0.8 x 1.5 (41 x 20 x 38mm)
- S9250 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 S9250 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) Always use a 4.8V NiCd w/gyro. Dry cells are rated at 1.5V each making the overall voltage 6V which will damage the gyro. The reason why this servo is recommended for 4.8V batteries, is that batteries will charge above their stated votlage level. A 6V 5-cell battery pack will charge above the 6V level. A voltage level of higher than 6V may damage internal circuitry. This is why we do not recommend 5-cell battery packs. If you use a 6V regulator to power this servo, the servo will operate normally without circuit damage.
- (2) When Using Systems With the Battery Fail Safe Function it Has a Higher Cut-Off Voltage Setting Which Will Cause Shorter Operation Time.
- (3) 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.
- When Used With GY501 Gyro: Switch the GY501 Servo Frame Rate Function (Frm) from NOR to High to Display the Performance of the Gyro to the Fullest. Setting Method:
- (1) Press the GY501 FUNC+ or - key to call the Servo Frame RateSetup Screen.
- (2) Press the DATA+ or - key to display High.
- 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. Otherwise they will work fine with current AM systems
