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. Product Images Features 7.5Kgf.cm peak torque - Listed maximum torque is 7.5Kgf.cm at 8.4V. 0.10sec fast response - Reaches 0.10sec/60° at 8.4V. Smaller X10 format - Shorter and lighter than the standard X10 V8.0 servo. HV voltage range - Supports DC 4.8V-8.4V operation. Coreless DC motor - Supports smooth and responsive control movement. Hardened steel gears - Improves strength in a compact wing-servo body. Aluminum alloy case - Helps rigidity and heat dissipation. Dual ball bearings - Uses 2BB support for smoother output operation. Programmable support - Technical data lists soft start and programmability. 23g lightweight build - Helps reduce weight in compact sailplane installations.
