Overview
The XQ-S2210D is the ultra-slim one: 10 mm through the case, 26 g, and 11 kg·cm at 8.4 V. That combination exists for airframes and frames where the servo has to disappear into the structure — a 10 mm case enters a thin foam or composite section that a 20 mm standard case simply cannot.
The thin case is not paid for in durability: the geartrain is stainless steel on twin ball bearings, and the 25T output spline is the same as the rest of the range, so horns and arms interchange.

| 6.0 V | 0.15 s/60° (400 °/s) | 8.2 kg·cm (0.80 N·m / 114 oz·in) | 170 mA | 2 A |
| 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 |

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 2 kg surface with its centre of pressure 30 mm from the spline centre needs 2 × 9.81 × 0.030 × 1.5 ≈ 0.88 N·m. The S2210D delivers 1.08 N·m at 8.4 V — about 23% headroom. Note that the 10 mm case usually forces a short horn, which works in your favour: every 5 mm removed from the horn length removes roughly 0.15 N·m of requirement.
FAQ
Can I run it directly from a 2S LiPo?
Yes. 8.4 V at full charge is the top rail in the inspection sheet and the rail the 11 kg·cm figure is measured at. Do not exceed it.
Why are there three different torque figures?
Torque, speed and current all scale with supply voltage. The sheet lists all three rails — 8.2 kg·cm at 6.0 V, 9.5 at 7.4 V, 11 at 8.4 V — so you can size the servo against the rail your BEC actually holds, not the marketing number.
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.
Is it waterproof?
Splash water resistance, customizable. No IP rating is published, so do not treat it as submersible.
How much is 11 kg·cm in oz·in?
About 153 oz·in, or 1.08 N·m.
