Overview
The S2210F is the 11 kg·cm member of XQ-POWER’s slim-wing family: 26 g, a 10 mm case, and 0.11 s/60° at 8.4 V. It shares its electrical and mechanical specification with the S2210D — what changes is the mounting, because the tabs on the F build are rotated 90° so the same servo sits in a bay where the rail runs the other way.
A 10 mm case carrying 11 kg·cm is the whole point. A standard 20 mm servo of the same torque will not enter a thin wing section at all, and the stainless geartrain means the thin case was not bought at the cost of gear life.

| 7.4 V | 0.13 s/60° (462 °/s) | 9.5 kg·cm (0.93 N·m / 132 oz·in) | 240 mA | 2.5 A |
| 8.4 V | 0.11 s/60° (545 °/s) | 11 kg·cm (1.08 N·m / 153 oz·in) | 300 mA | 3 A |

What’s in the box
- 1 × XQ-S2210F servo
- 1 × POM horn set
- 1 × mounting screw pack
Optional: metal horn, sold separately.
How to size it
Torque budget = load at the horn × horn length from spline centre × 1.5 safety factor.
Worked example: a 1.8 kg surface whose centre of pressure sits 28 mm from the spline centre needs 1.8 × 9.81 × 0.028 × 1.5 ≈ 0.74 N·m. The S2210F delivers 1.08 N·m at 8.4 V — about 1.45× headroom. On a wing surface the load is rarely static: if the surface can flutter, treat 1.5 as a floor and check the hinge for slop before blaming the servo.
FAQ
Can I run it directly from a 2S LiPo?
Yes. 8.4 V at full charge is the top rail in the sheet and the rail the 11 kg·cm figure is measured at. Do not exceed it.
Why are there three torque figures?
Torque, speed and current all scale with supply voltage. The sheet lists 8.2 kg·cm at 6.0 V, 9.5 at 7.4 V and 11 at 8.4 V so you can size against the voltage your BEC actually holds.
What is different about the F version?
The mounting tabs are rotated 90° relative to the S2210D. Electrical and mechanical specification is otherwise identical — same 26 g, same 10 mm case, same 25T spline.
Does it rotate continuously?
Travel is 360° when commanded over 1000–2000 µs, as a factory customization. Standard units work across the 800–2200 µs window.
How much is 11 kg·cm in oz·in?
About 153 oz·in, or 1.08 N·m.
