Compact Futaba S136G servo for reliable gear locking

The Futaba S136G Compact Retract Servo was developed for modellers who require a neat, reliable actuator for mechanical landing gear. Its reduced footprint fits wing bays cleanly while offering the 180 degree movement needed for positive lock at both extremes.

Notable Attributes of the Futaba S136G

  • Compact Design: Designed to fit into tight installation spots in wings and bays.
  • Metal Gear Set: Provides greater resistance to wear compared with plastic gearing.
  • Two Ball Bearings: Keeps travel smooth and reduces play.
  • 3-Pole Motor: Good efficiency for repeatable operation.
  • 180-Degree Travel: Full range motion for secure gear positions.

Specifications

  • Length: 46mm
  • Width: 23mm
  • Height: 25mm
  • Torque: 92 oz/in @ 4.8V (6.6 kg/cm @ 4.8V)
  • Speed: .58 seconds/60 degrees @ 4.8V
  • Weight: 42g

A practical choice for mechanical retract setups, the Futaba S136G balances compact sizing with sturdy construction for dependable gear control.

Use firm mounting points and preload as recommended to prevent slop; space permitting, fit vibration-damping washers to protect the servo and its linkages.
The published specs are at 4.8V; consult Futaba guidelines before increasing voltage as it can affect torque and longevity.
Manually cycle the gear several times on the bench and inspect linkages for tightness; ensure the servo reaches both stops without binding.
