Overview
The KST SV7012-12 is an SHV 4-pole brushless servo motor designed for large scale RC planes, industrial UAVs, and robotics. It supports a rated voltage of DC12.0V (fits 3S LiPo battery) and provides up to 75Kgf.cm torque @13.0V with 0.10sec/60deg no-load speed @13.0V. The default travel is +/-100deg (200deg total) and is programmable.
Key Features

Details
Built for large-scale RC planes, industrial UAVs, and robotics, the SV7012-12 combines high torque with fast response on SHV power.
High-torque output supports demanding control surfaces on big airframes and high-load robotic mechanisms.
DC 12V rated voltage makes it a natural fit for 3S LiPo setups commonly used in UAV and robotics builds.
A CNC aluminum alloy housing improves rigidity and helps shed heat during sustained high-load operation.
Programmable travel and signal range make it easier to tune end points for custom linkages and control geometry.
Included hardware and multiple horn styles help match the servo to different mounting patterns and control arms.
