The KST A08 LV V6.0 Micro Coreless Digital Servo is a low-voltage micro servo optimized for unpowered gliders, compact RC models, and 1S LiPo-style setups. It delivers up to 2.0kgf.cm torque at 4.2V and 0.15sec/60° speed at 4.2V.
The A08 LV is built around a coreless DC motor, hardened steel gears, 2BB support, and an aluminum alloy case. Its DC 3.5V-4.2V range makes it a focused choice for low-voltage RC systems where weight and servo bay space are limited.
