S0009M / S0017M Digital Metal-Gear RC Servo, Two Size Options
Replace a small steering or control servo after matching the mounting space and receiver setup. The S0009M and S0017M are separate metal-geared digital servo options for compatible RC models. They are for hobby builders selecting one actuator, not a complete radio-control system.
- ✅ Match the servo to the available space — Two body sizes let you compare the mounting bay before ordering.
- ✅ Connect to a compatible receiver setup — The attached three-wire lead carries the servo's control and supply connections.
- ✅ Choose a linkage attachment — The selected servo comes with an accessory set of horns and fixings.
- ✅ Plan the installation without a built-in battery — Power comes from a suitable external receiver/BEC arrangement within the stated voltage range.
Choose by dimensions and control requirements, not scale alone
The 9g servo selector corresponds to S0009M and the 17g servo selector to S0017M. These labels identify size classes rather than the specified assembled weights: the text states approximately 13.5 g and 21 g respectively. The larger model has a larger body and a higher stated torque range, so they are not interchangeable simply because both use metal gears.
Check mounting-ear spacing, spline, connector polarity, control signal and supply capacity against the model before fitting. The stated supply range is 4.8–6 V DC and the control specification is 1520 μs/333 Hz. Model scale alone does not confirm drop-in fit to a particular car, boat, helicopter or aircraft.
One selected servo and its own horn/fixing accessory set are included. A receiver, ESC/BEC, battery, charger and vehicle are not included. Speed figures conflict between the text and gallery, so no specific transit time is asserted. No water-protection rating or guaranteed impact resistance is confirmed for these two options.
The S0009M is the smaller metal-geared option; the supplied horn selection differs from S0017M.
The S0017M uses a larger body and its own accessory set.
Compare the S0009M mounting centres and body with the model's servo bay.
The smaller body is approximately 23 × 12 × 27.3 mm.
The S0017M body is approximately 28 × 13.2 × 29.6 mm with wider mounting centres.
The attached lead connects to a compatible receiver/BEC arrangement.
Metal gears are illustrated inside the smaller servo; no waterproof rating is established.
The larger servo is a separate choice, not included alongside the smaller option.
Check the mounting-ear spacing, output spline and connector before choosing the larger servo.
