Here is the Futaba S9253 Digital High Speed Rudder F3C Servo for Gyro
with High-Current Wire Lead and "J" Connector Pre-Installed.
This servo can create high-current draw from your batteries.
If utilizing NiMH or Li-Po batteries, get them to capable
of delivering sufficient Amps.
FEATURES: Digitally enhanced microprocessors cut about 1/2 the response time
from transmitter input to servo reaction.
Dual ball bearings on production shaft
Coreless motor with Plastic/nylon gear train
High speed
High current, high capacity cable lead with low resistance
Gold plated connectors
Case is made of black plastic
Dust and water-resistant (perhaps not waterproof)
Designed exclusively as a tail rotor servo for F3C, 30, 46 and 60
sized helicopters, particularly with SMM gyros like GY401,
GY502. (Will Not assist the GY601 gyro.)

OPINIONS: S9253 Digital Servo Precautions,
-It is better to avoid long leads and Y-harnesses specially with
standard grade wires. If dilemmas are encountered, consider using
heavy responsibility wire such as for instance Futaba's high quality Series or Hobbico's
Pro Series ,minimizing lead lengths, and/or the removal of Y-harnesses.
-Current Drain: Futaba S9253 Servo is specially created for high-
torque and high-speed, for that reason very high present drain is
normal at startup. For ultimate performance when utilizing this servo,
please review these points.
(1) Always utilize a 4.8V NiCd w/gyro. Dry cells are ranked at 1.5V
each making the general voltage 6.0V that will damage the gyro.
(2) When utilizing systems because of the battery fail safe function it has
a higher cut-off voltage environment that may cause shorter
operation time.
(3) Whenever installing the servo please always check pushrod linkage to make
sure there is absolutely no binding in order to avoid extortionate power
consumption and reduce the life of motor and battery.
When Combined with GY501 Gyro:
Switch the GY501 servo frame price function (Frm) from "NOR" to
"tall" to produce the performance of this 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 display "High".
This electronic servo cannot be used in combination with the next * AM *
transmitters while the servo neutral sign is: 1310us).
