The KST A06/A06H/A06N V6.0 Micro Coreless Digital Dual Bearing Servo series is built for ultra-light RC glider installations where compact size, low weight, and precise control matter. The series supports DC 3.5V-4.2V operation and reaches up to 1.4Kgf.cm torque at 4.2V with 0.11sec/60° speed at 4.2V. The three Shopify variants share the same verified core specification, including a coreless DC motor, hardened steel gears, aluminum alloy case, 2BB dual ball bearings, and 1520μs / 333Hz control signal. The difference is the mounting style: A06 standard tabs, A06H horizontal tabs, and A06N lugless mounting. With a compact 20.5 x 7 x 18.8mm body and approximately 7g weight, the A06 V6.0 series is suitable for F3K and other small glider builds where servo fit, linkage geometry, and weight balance are critical. Product Images Features Three mounting styles - Choose A06 standard tabs, A06H horizontal tabs, or A06N lugless mounting for different glider layouts. 1.4Kgf.cm peak torque - Listed output reaches 1.4Kgf.cm at 4.2V. 0.11sec fast response - Listed speed reaches 0.11sec/60° at 4.2V. LV micro-servo voltage range - Supports DC 3.5V-4.2V operation. Coreless DC motor - Helps provide smooth control response in lightweight builds. Hardened steel gears - Improves durability for repeated control-surface movement. Aluminum alloy case - Keeps the servo body rigid while staying compact. Dual ball bearings - Uses 2BB construction for smoother output-shaft support. 7mm slim body - Fits narrow fuselage and wing installations where space is limited. F3K-focused design - Practical for small glider builds requiring low weight and precise response.
