This is the Futaba S3155 Digital High Speed Wing Servo.|
Ideal for wing-mounted applications requiring high speed such as gliders.
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.
Dust and water resistant-not waterproof
Compact design is especially suited for easy installation inside
the wing of smaller gliders, jets and electric planes

S3155 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 motor and battery life.
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 it will work fine with current AM systems *****
