KST FZ320 is a fast HV servo with metal gears, suitable for RC gliders and jet models (“jets”). The gears are precise and backlash-free. Low electromagnetic emission (“low EMF”) technology reduces the risk of interference with other electronics in the model.
It is powered by a coreless motor. The hardened steel gears are supported by two ball bearings. The machined (CNC) aluminium alloy case is strong and lightweight. The servo weighs 20g. It operates from 6-8.4V, making it suitable for 2S LiPo power. At 7.4V, it delivers 5.5kg-cm of torque and a speed of 0.09s/60°. Resolution is better than 2uS.
With a standard 1000-2000uS signal, it has a travel of 100° (±50°), while in the extended 500-2500uS range it reaches up to 200° (±100°). The connection cable has a 26AWG cross-section.
