This is the Futaba S9154 Digital Low Profile High Speed Aileron Servo|
with J Connector.
Designed for aileron applications on model aircraft.
This servo can produce high-current draw from your batteries.
If using NiMH or LiPo batteries, make sure they are capable
of delivering sufficient amps.
Digitally enhanced microprocessors cut in half the response time
from transmitter input to servo reaction
Dust and water resistant-not water proof
Low profile aero design is specially suited for wing installations
with thin airfoils
Black plastic case
One year warranty

S9154 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: This digital servo is specially designed for high-
torque or high-speed, therefore very high current drain is normal
at startup. For ultimate performance when using this servo please
review the following points.
1. Radio systems with the Battery Fail Safe function have a
higher cut-off voltage setting which will cause shorter
2. 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
A note on Coreless motors: conventional servo motors have a steel
core armature wrapped with wire that spins inside the magnets. In
a Coreless design, the armature uses a thin wire mesh that forms a
cup that spins around the outside of the magnet eliminating the
heavy steel core. This design results in smoother operation and
faster response time.
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 Terratop,
T3EGX, T3PGE, T2NL, T2LGX, T2FR, T2PK series.
***** Otherwise they will work fine with current AM systems *****
No other arms will work on this servo, because of the unique
