The Servo Digital Heli produced by Futaba, is classified in R/C Models - System - Servo - Standard Servos
This is the S9250 Digital Servo w/Two Ball Bearings for
Helicopter and Aircraft use and is sold 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.
QUALITIES: Digitally Improved Microprocessors Cut About 1/2 the Response Time
From Transmitter Input To Servo Reaction.
Coreless Motor
Dual Ball Bearing production Shaft
Metal Gears
High Speed
Case consists of Black Plastic
Dust and water-resistant (maybe not Waterproof)
Great for Helicopters or Airplanes Where Higher Torque and Speed are
required.
One year warranty.

REVIEWS: S9250 Digital Servo Precautions,
-It is better in order to avoid long leads and Y-harnesses specially with
standard grade cables. If issues are experienced, consider using
heavy duty cable such as for example Futaba's Heavy Duty Series or Hobbico's
Pro Series ,minimizing lead lengths, and/or the removal of Y-harnesses.
-Current Drain: Futaba S9250 Servo is especially created for High-
Torque and High-Speed, consequently high Current Drain Is
Normal At Startup. For Ultimate Efficiency When Using This Servo
Please Review The Following Points.
(1) Always utilize a 4.8V NiCd w/gyro. Dry cells are rated at 1.5V each
making the overall voltage 6.0V that may harm the gyro.
__---------------------------------------------------------------------------
The good reason why this servo is recommended for 4.8V batteries, usually batteries
will cost above their stated votlage degree. A 6V 5-cell battery pack will
charge above the 6 Volt degree. A voltage amount of greater than 6 Volts may
damage interior circuitry. This is the reason we don't recommend 5-cell battery
packs.If you use a 6 volt regulator to energy this servo, the servo will
operate normally without circuit damage.
---------------------------------------------------------------------------
(2) when working with Systems with all the Battery Fail Safe Function it Has
a Higher Cut-Off Voltage Setting Which Will Cause Shorter
Operation Time.
(3) When setting up the Servo Please check always Pushrod Linkage To Make
Sure there's absolutely no Binding to be able to avoid Excessive Power
Consumption and Decrease the Life of this engine and Battery.
When Used in combination with GY501 Gyro:
Switch the GY501 Servo Frame Rate Function (Frm) from "NOR" to
"High" to produce the Efficiency of Gyro towards 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 show "High".
This electronic servo can not be used in combination with the following * have always been *
transmitters since the servo basic signal is: 1310us).
CONQUEST have always been, FG Series (T4FG, T5FGK,T6FG, T6FGK, T7FGK), New Terra-
top, T3EGX, T3PGE, T2NL, T2LGX, T2FR, T2PK series.
**** Otherwise they will work fine with present AM systems *****
