Futaba S9102 Servo Aileron — Low-profile aileron servo for in-wing RC models  [S9102]

Low-profile aileron servo for in-wing installation

The Futaba S9102 is an aileron servo intended for in-wing installation in RC model aircraft. Its thin profile and coreless motor design are targeted at builds where limited space and reliable aileron response are priorities. 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 high-current aileron events. Use standard RC mounting practices for in-wing servos and secure linkages to keep travel and centering 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.
