The Digital Heli Rudder High Speed Servo produced by Futaba, is classified in R/C Models - System - Servo - Standard Servos
Here is the Futaba S9254 Digital Coreless High Torque,
tall Speed Helicopter Gyro Servo with J Connector.
This servo can create high-current draw from your batteries.
If using NiMH or Li-Po batteries, make sure they are capable
of delivering adequate Amps.
QUALITIES: Coreless motor for paid off weight and high-speed response
Digitally enhanced microprocessors cut in half the reaction time
from transmitter input to servo reaction
Dust and water resistant-not water proof
Black synthetic case
One year warranty

COMMENTS: S9254 Digital Servo Precautions,
-It is most beneficial in order to avoid long leads and Y-harnesses specially with
standard grade wires. If dilemmas are encountered, consider using
heavy duty wire like Futaba's high quality Series or Hobbico's
Pro Series,minimizing lead lengths, and/or removing Y-harnesses.
-Current Drain: This electronic servo is specifically created for high-
torque or high-speed, therefore high present drain is normal
at startup. For ultimate performance when working with this servo please
review the following points.
1. Broadcast systems aided by the Battery Fail secure function have a
higher cut-off voltage environment which will cause shorter
operation time.
2. When setting up the servo, please check always pushrod linkage to
make sure there isn't any binding to prevent excessive
power usage and decrease the life of motor and
battery.
A note on coreless motors. A regular servo motor has a steel
core armature wrapped with wire that spins in the magnets. In
a coreless design, the armature utilizes a thin wire mesh that forms a
cup that spins round the outside of the magnet eliminating the
heavy metal core. This design results in smoother operation and
faster response time.
This servo is ranked as high-torque for helicopter gyro applications,
the rating wouldn't be considered high-torque for airplane control
surface or monster truck steering applications.
This digital servo cannot be used with these * AM *
transmitters because the servo neutral signal is: 1310us.
CONQUEST AM, FG Series (T4FG, T5FGK,T6FG, T6FGK, T7FGK), Brand New Terra-
top, T3EGX, T3PGE, T2NL, T2LGX, T2FR, T2PK show.
***** Otherwise they are going to work fine with present AM systems *****
No other arms will work on this servo, because of the unique
spline size.
***** kit set with this servo is FUTM3445 (gear set S9253)*****
