This is the S9250 Digital Servo w/Two Ball Bearings for
Helicopter and Aircraft use and Comes with "J" Connector Pre-Installed.
This servo can produce high-current draw from your batteries.
If using NiMH or Li-Po batteries, make sure they are capable
of delivering sufficient Amps.
FEATURES: Digitally Enhanced Microprocessors Cut About 1/2 the Response Time
From Transmitter Input To Servo Reaction.
Coreless Motor
Dual Ball Bearing Output Shaft
Metal Gears
High Speed
Case is Made of Black Plastic
Dust and Water Resistant (Not Waterproof)
Great for Helicopters or Airplanes Where Higher Torque and Speed are
Needed.
One year warranty.

COMMENTS: 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 6.0V 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 6 Volt level. A voltage level of higher than 6 Volts may
damage internal circuitry. This is why we do not recommend 5-cell battery
packs.If you use a 6 volt 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 Rate
Setup 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 Terra-
top, T3EGX, T3PGE, T2NL, T2LGX, T2FR, T2PK series.
**** Otherwise they will work fine with current AM systems *****
