Spektrum SX108 Micro Metal Gear Servo, SPMSSX108
A steering servo for small models — and a neat way to drive a two-speed transmission or a dig unit. It weighs 10 grams and puts out 41.8 oz-in (about 3.0 kg·cm) at 6 V, which is a lot for this size given the full metal gear train and dual bearing output support.
Torque 41.8 oz-in at 6 V (34.9 oz-in at 4.8 V) | Speed 0.08 s / 60° at 6 V | Size 23 × 12 × 22 mm, 10 g |

- Coreless motor, smooth and free of stepping
- 20T spline output
- Built for steering micro and mini models, and equally at home on a two-speed transmission or a dig unit

Compatibility and notes
The manufacturer quotes torque and speed at 4.8 V and 6 V — that is the range the servo is specified for. Running it outside that range is left to your own judgement.
Horns use the standard 20T spline — check that your horn matches that size.
Who it is for
