Futaba S9102 Low-Profile Aileron Servo for In-Wing RC Models  [S9102]

Slim aileron servo for in-wing mount

The Futaba S9102 is an aileron servo designed for in-wing installation in RC model aircraft. Its slim profile and coreless motor target builds where space is limited and precise aileron response is needed. The unit includes a J-type connector and a single-ball-bearing arrangement described in the original documentation, with features listed below retained from the source information.

When planning installation, confirm your battery and power system can supply the servo's peak current demand, particularly when using NiMH or LiPo packs, to avoid voltage sag during heavy aileron use. Use standard RC mounting practices for in-wing servos and secure linkages so travel and centering remain predictable during setup and trimming.

Use the S9102 where a slim, in-wing-compatible aileron servo is required and plan the power system and linkage geometry during build and trimming to achieve consistent control surface response and reliable flight tuning.
