Futaba S9102 Aileron Servo — Compact Low-Profile Unit  [S9102]

Designed for in-wing aileron installations

The Futaba S9102 is an aileron servo intended for mounting inside RC model aircraft wings, combining a coreless motor with a reduced-thickness case to suit confined spaces. The package specifies a J-type connector and references a single-ball-bearing arrangement in the original notes, while the feature list below preserves the stated details.

Confirm your battery and regulator arrangement can handle the servo's peak current draw to avoid voltage sag during demanding aileron inputs, and use solid mounting points and secure linkages to keep travel and centering stable during trimming and flight tuning.

Deploy the S9102 when a narrow in-wing-compatible aileron servo is needed and plan electrical supply and linkage layout at build time to ensure reliable surface control and predictable tuning.
