This is the S9250 Digital Servo w/Two Ball Bearings for
Helicopter and Aircraft usage and Comes with "J" Connector Pre-Installed.
This servo can produce high-current draw from your own batteries.
If using NiMH or Li-Po batteries, cause them to become capable
of delivering enough 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 consists of Ebony Plastic
Dust and waterproof (perhaps not Waterproof)
Great for Helicopters or Airplanes in which Higher Torque and Speed are
Needed.
One year guarantee.

COMMENTS: S9250 Digital Servo Precautions,
-It is better to avoid long leads and Y-harnesses especially with
standard grade wires. If issues are experienced, consider using
heavy duty cable such as for instance Futaba's high quality Series or Hobbico's
Pro Series ,minimizing lead lengths, and/or getting rid of Y-harnesses.
-Current Drain: Futaba S9250 Servo is particularly created for High-
Torque and High-Speed, Therefore quite high active Drain Is
Normal At Startup. For Ultimate Efficiency When Working With This Servo
Please Review The Next Points.
(1) Always use a 4.8V NiCd w/gyro. Dry cells are ranked at 1.5V each
making the entire voltage 6.0V that may harm the gyro.
__---------------------------------------------------------------------------
The reasons why this servo is advised for 4.8V batteries, is that batteries
will cost above their stated votlage degree. A 6V 5-cell battery power will
charge above the 6 Volt degree. A voltage degree of more than 6 Volts may
damage interior circuitry. For this reason we don't recommend 5-cell battery
packs.If you utilize a 6 volt regulator to power this servo, the servo will
operate ordinarily without circuit damage.
---------------------------------------------------------------------------
(2) when utilizing Systems With the Battery Fail secure Function it Has
a Higher Cut-Off Voltage Setting Which Will Cause Shorter
Operation Time.
(3) Whenever setting up the Servo Please always check Pushrod Linkage To Make
Sure There isn't any Binding so that you can avoid Excessive Power
Consumption and reduce steadily the Life associated with the engine and Battery.
When Used in combination with GY501 Gyro:
Switch the GY501 Servo Frame Rate Function (Frm) from "NOR" to
"tall" to produce the Performance of this Gyro towards the Fullest.
Setting Method:
(1) Press the GY501 FUNC+ or - key to phone the Servo Frame Rate
Setup Screen.
(2) Press the DATA+ or - key to display "High".
This digital servo cannot be combined with the following * have always been *
transmitters while 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'll work fine with current AM systems *****
