Low profile aileron solution featuring Futaba S9154

The Futaba S9154 Digital High Speed Aileron Servo combines compact packing with precise control for model aircraft. It is especially suited to wings with shallow rib depth where a slim servo body is required.

High-response coreless drive and digital processing

The S9154 uses a coreless motor and advanced digital processing to cut response delay between transmitter commands and control surface movement. Pilots will notice smoother transitions and quicker corrections during flight.

Specifications

  • Speed: 0.14 sec/60° at 4.8V
  • Torque: 64 oz/in (5.8 kg/cm) at 4.8V
  • Dimensions: 1.9" x 1.1" x 1.0" (48mm x 28mm x 25mm)
  • Weight: 1.9 oz (53g)
  • Power Supply: 4.8V (not recommended for 6V use)

Practical installation advice

Confirm your battery and regulator can supply short, high current bursts. Avoid long thin servo leads and parallel splits that can drop voltage. Keep linkages free of play but do not overtighten, as binding will increase current draw and reduce efficiency.

Will the S9154 fit inside narrow wing bays?

Yes, its low-profile case is made to fit shallow bays, but you should measure internal clearance and allowance for connectors before final mounting.

Should I use a separate BEC for power-hungry setups?

If you run multiple digital servos or heavy loads, a regulated supply or separate battery eliminator circuit can help prevent voltage sag and protect the receiver.

How often should I check the servo linkages?

Inspect linkages before each flying session for free movement and secure connectors. Catching binding or worn parts early avoids servo overheating and premature wear.
