KST X10 Mini V8.0 Digital Metal Gear Servo 7.5kg 0.1sec
The KST X10 Mini V8.0 Digital Metal Gear Servo is the smaller X10-series wing servo for sailplane and glider installations where a compact body and lower weight are preferred. The verified specification lists up to 7.5Kgf.cm torque at 8.4V and 0.10sec/60° speed at 8.4V.
Compared with the standard X10 V8.0, the X10 Mini V8.0 uses a shorter 30 x 10 x 29.6mm case and approximately 23g weight while retaining hardened steel gears, coreless DC motor, aluminum alloy case, 2BB support, and 1520μs / 333Hz working frequency.
The title may appear as 6.8kg in some listings because the specification gives 6.8Kgf.cm at 7.4V; the same technical sheet lists 7.5Kgf.cm at 8.4V. This description separates the voltage-specific torque ratings so builders can configure power safely.
