In-Wing Aileron Servo S9102 by Futaba — Compact Low Profile  [S9102]

Compact aileron servo tailored for wing installations

The Futaba S9102 is intended for in-wing installation in RC model aircraft and is built around a coreless motor and slim casing for space-constrained assemblies. The unit carries a J-type connector and a single-ball-bearing arrangement as noted in source materials, and the feature list below preserves the original specification details.

Before installation, confirm your battery system can cope with the servo's peak current requirements, especially when using NiMH or LiPo packs, to reduce the risk of voltage sag during heavy aileron demands. Follow customary in-wing mounting procedures and lock down linkages so trim and travel remain repeatable.

The S9102 suits models needing a thin in-wing aileron servo; verify power delivery and linkage geometry during the build to maintain consistent control feel and tuning.
