S9153 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: Futaba S9153 Servo is Specially Designed for High-
Torque and High-Speed, Therefore Very High Current Drain Is
Normal At Startup. For Ultimate Performance When Using This Servo
Please Review The Following Points.
(1) When Using Systems With the Battery Fail Safe Function it Has
a Higher Cut-Off Voltage Setting Which Will Cause Shorter
Operation Time.
(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 Battery.
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 Terra-
top, T3EGX, T3PGE, T2NL, T2LGX, T2FR, T2PK series.

**** Otherwise they will work fine with current AM systems *****


Servo Accessory Package (FUTM2042) includes the two large horns and
all mounting hardware mentioned above.
A note on Coreless motors: conventional servo motors have a steel
core armature wrapped with 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 is much lighter resulting in smoother
operation and faster response time.
