Overview
The XQ-S2007D is the fast one in this range. 0.06 s/60° at 8.4 V is a full 60° of travel in 60 milliseconds — 1000 °/s — which is quick enough that the servo stops being the limiting factor in a fast control-surface linkage. It does that on 20 g and a 12 × 23 × 27.1 mm case.
Two details matter for integration. The geartrain is stainless steel, so the small case is not paid for in durability. And the output is a 25T spline — the same as the larger models in the range — so horns are interchangeable rather than model-specific.

How to size it
Torque budget = load at the horn × horn length from spline centre × 1.5 safety factor.
Worked example: a 1.5 kg surface with its centre of pressure 25 mm from the spline centre needs 1.5 × 9.81 × 0.025 × 1.5 ≈ 0.55 N·m. The S2007D delivers 0.69 N·m at 8.4 V — about 25% headroom, which is the right place to be for a surface that sees airflow rather than static load. If the linkage is shock-loaded, raise the factor to 2.5 and re-run before stepping up.
FAQ
Can I run it directly from a 2S LiPo?
Yes. A 2S pack is 8.4 V at full charge, which is the top rail in the inspection sheet and the one the 7 kg·cm figure is measured at. There is no headroom above it.
Why are there three different torque figures?
Because torque, speed and current all scale with supply voltage, and the sheet publishes all three rails rather than only the best: 5 kg·cm at 6.0 V, 6.2 at 7.4 V, 7.0 at 8.4 V. Compare servos at the same rail.
Does it rotate continuously?
Travel is 360° when commanded over 1000–2000 µs, as a factory customization. The standard unit works across the 800–2200 µs window. Continuous rotation is set at build time.
Is it waterproof?
Splash water resistance, customizable, per the inspection sheet. No IP rating is published, so do not treat it as submersible.
How much is 7 kg·cm in oz·in?
About 97 oz·in, or 0.69 N·m.
