Operating principle and design
KST X20-2208 V8.0 is a digital HV servo drive based on advanced brushless motor technology. Unlike traditional motors, the brushless design offers significantly faster response speed, efficiency and durability . The high-precision digital controller processes the signal at a frequency of 333 Hz (1520 µs), ensuring exceptional accuracy and smooth movement without jerking.
The rugged CNC-machined aircraft-grade aluminum body not only adds rigidity to the structure, but also transforms the body into an efficient heatsink that removes heat from the engine and electronics . The HLS (High Life Span) hardened steel gearbox with six ball bearings ensures durability and resistance to the shock loads inevitable during hard drone landings .
